Abstract

IEC 60335-2-72:2021 deals with the safety of powered ride-on and powered walk-behind machines intended for commercial indoor or outdoor use for the following applications:
- sweeping,
- scrubbing,
- wet or dry pick-up,
- polishing,
- application of wax, sealing products and powder-based detergents,
- shampooing
of floors.
These machines have a cleaning motion which is more linear than lateral or periodic. This standard applies to machines for commercial use. The following list, although not comprehensive, gives an indication of locations that are included in the scope:
- public use areas such as hotels, schools, hospitals;
- industrial locations, for example factories and manufacturing shops;
- retail outlets, for example shops and supermarkets;
- business premises, for example offices and banks;
- all uses other than normal housekeeping purposes.
These machines may be equipped with a traction drive system. The following power systems are covered:
- internal combustion engines,
- mains powered motors up to a rated voltage of 250 V for single-phase appliances and 480 V for other appliances,
- battery-operated machines.
Battery-operated machines may be equipped with a built-in battery charger.
This standard does not apply to
- floor treatment appliances for household use (IEC 60335-2-10);
- floor treatment machines for commercial use (IEC 60335-2-67);
- spray extraction machines for commercial use (IEC 60335-2-68);
- wet and dry vacuum cleaners, including power brush, for commercial use (IEC 60335-2-69);
- road sweepers;
- machines designed for use on slopes with a gradient exceeding 20 %;
- machines equipped with a power take-off (PTO);
- machines designed for use in corrosive or explosive environments (dust, vapour or gas);
- machines designed for picking up hazardous dusts (as defined in IEC 60335-2-69), inflammable substances, or glowing particles;
- machines designed for use in vehicles or on board of ships or aircraft.
Attention is drawn to the fact that
- in many countries additional requirements on the safe use of the equipment covered can be specified by the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities;
- ride-on machines designed for transport over public roads can be subject to additional requirements (e.g. lighting, license plate etc.).
Requirements for fuel-cells are under consideration. This fifth edition cancels and replaces the fourth edition published in 2016. It constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition (minor changes are not listed):
- editorial and technical alignment with IEC 60335-1:2020;
- rearrangement of subclauses to consistent numbering 22.101 to 22.113.
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments. It was established on the basis of the sixth edition (2020) of that standard.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
IEC 60335-2-72 has been prepared by subcommittee 61J: Electrical motor-operated cleaning
appliances for commercial use, of IEC technical committee 61: Safety of household and
similar electrical appliances. It is an International Standard.
This fifth edition cancels and replaces the fourth edition published in 2016. It constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous
edition (minor changes are not listed):
– editorial and technical alignment with IEC 60335-1:2020;
– rearrangement of subclauses to consistent numbering 22.101 to 22.113.

The text of this International Standard is based on the following documents:
CDV Report on voting
61J/738/CDV 61J/744A/RVC
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement,
available at www.iec.ch/members_experts/refdocs. The main document types developed by
IEC are described in greater detail at www.iec.ch/standardsdev/publications.
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its
amendments. It was established on the basis of the sixth edition (2020) of that standard.
NOTE 1 When “Part 1” is mentioned in this standard, it refers to IEC 60335-1.
This part 2 supplements or modifies the corresponding clauses in IEC 60335-1, so as to
convert that publication into the IEC standard: Particular requirements for floor treatment
machines with or without traction drive, for commercial use.
When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies
as far as is reasonable. When this standard states “addition”, “modification” or “replacement”,
the relevant text in Part 1 is to be adapted accordingly.
NOTE 2 The following numbering system is used:
– subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1;
– unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including
those in a replaced clause or subclause;
– additional annexes are lettered AA, BB, etc.
NOTE 3 The following print types are used:
– requirements: in roman type;
– test specifications: in italic type;
– notes: in small roman type.
NOTE 4 The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations may need a transitional period following publication of a new, amended or revised IEC publication in
which to make products in accordance with the new requirements and to equip themselves for conducting new or
revised tests.
It is the recommendation of the committee that the content of this publication be adopted for implementation
nationally not earlier than 12 months or later than 36 months from the date of publication.
The following differences exist in the countries indicated below.
– Annex AA: The CO-emission of LPG driven machines, intended to be used indoors, has to comply with the
value specified in Annex BB. The result shall be documented (Germany).
– Annex BB: For machines intended to be used indoors, except single cylinder engines, the exhaust gas shall
not contain more than 0,1 % volume of carbon monoxide (CO). If adjustments are necessary, the adjusting
means shall be easily accessible. The measurement shall be carried out with a warm engine, idling, using
98 % propane. The revolution speed of the engine shall be documented (Germany).
Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective and the
associated noun are also in bold.
A list of all parts of the IEC 60335 series, under the general title: Household and similar
electrical appliances – Safety, can be found on the IEC website.

contents. Users should therefore print this document using a colour printer.

INTRODUCTION
It has been assumed in the drafting of this International Standard that the execution of its
provisions is entrusted to appropriately qualified and experienced persons.
This standard recognizes the internationally accepted level of protection against hazards such
as electrical, mechanical, thermal, fire and radiation of appliances when operated as in
normal use taking into account the manufacturer's instructions. It also covers abnormal
situations that can be expected in practice and takes into account the way in which
electromagnetic phenomena can affect the safe operation of appliances.
This standard takes into account the requirements of IEC 60364 as far as possible so that
there is compatibility with the wiring rules when the appliance is connected to the supply
mains. However, national wiring rules may differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
When a part 2 standard does not include additional requirements to cover hazards dealt with
in Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into
consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features that impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of
the requirements and, if found to be substantially equivalent, may be considered to comply
with the standard.

This part of IEC 60335 deals with the safety of powered ride-on and powered walk-behind
machines intended for commercial indoor or outdoor use for the following applications:
– sweeping,
– scrubbing,
– wet or dry pick-up,
– polishing,
– application of wax, sealing products and powder-based detergents,
– shampooing
of floors.
These machines have a cleaning motion which is more linear than lateral or periodic.
NOTE 101 By contrast, the cleaning motion of machines covered by IEC 60335-2-67 is more lateral or periodic
than linear.
NOTE 102 This standard applies to machines for commercial use. The following list, although not
comprehensive, gives an indication of locations that are included in the scope:
– public use areas such as hotels, schools, hospitals;
– industrial locations, for example factories and manufacturing shops;
– retail outlets, for example shops and supermarkets;
– business premises, for example offices and banks;
– all uses other than normal housekeeping purposes.
These machines may be equipped with a traction drive system. The following power systems
are covered:
– internal combustion engines,
– mains powered motors up to a rated voltage of 250 V for single-phase appliances and
480 V for other appliances,
– battery-operated machines.
Battery-operated machines may be equipped with a built-in battery charger.
This standard does not apply to
– floor treatment appliances for household use (IEC 60335-2-10);
– floor treatment machines for commercial use (IEC 60335-2-67);
– spray extraction machines for commercial use (IEC 60335-2-68);
– wet and dry vacuum cleaners, including power brush, for commercial use
(IEC 60335-2-69);
NOTE 103 IEC 60335-2-67, IEC 60335-2-68 and IEC 60335-2-69 cover only machines without traction drive.
– road sweepers;
NOTE 104 In Europe, EN 13019 covers road sweepers.
– machines designed for use on slopes with a gradient exceeding 20 %;
– machines equipped with a power take-off (PTO);
– machines designed for use in corrosive or explosive environments (dust, vapour or gas);
– machines designed for picking up hazardous dusts (as defined in IEC 60335-2-69),
inflammable substances, or glowing particles;
– machines designed for use in vehicles or on board of ships or aircraft.
NOTE 105 Attention is drawn to the fact that
– in many countries additional requirements on the safe use of the equipment covered can be specified by the
national health authorities, the national authorities responsible for the protection of labour, the national water
supply authorities and similar authorities;
– ride-on machines designed for transport over public roads can be subject to additional requirements (e.g.
lighting, license plate etc.).
NOTE 106 Requirements for fuel-cells are under consideration.

normal operation
conditions under which the machine is operated in normal use, as intended by the
manufacturer
It denotes the load corresponding to the rated power input or the highest obtainable load of
all particular loads of the various functions that can be operated at the same time in
accordance with the manufacturer’s instructions. For machines provided with a seat or an
operator platform, a mass of 75 kg secured in position at the appropriate height is used to
simulate the operator in the most unfavourable position. Internal combustion engine driven
machines are operated with the fuel specified by the manufacturer except where otherwise
stated in this standard.
Operational functions include all treatment and driving functions.
Operation of the machine under following conditions:
– the battery is charged, the battery being initially discharged to such an extent that the
appliance cannot operate;
– if possible, the appliance is supplied from the supply mains through its standalone battery
charger, the battery being initially discharged to such an extent that the appliance cannot
operate. The appliance is operated as specified in the main part of this standard;
– if possible, built-in battery chargers are connected to the circuit of Figure 107. The
variable resistor is adjusted so that the current in the circuit is the rated DC output
current when the battery charger is supplied at rated voltage. When the charging current
is controlled by the state of charge of the battery, the variable resistor and the capacitor
are replaced by a discharged battery of the type and having the largest capacity specified
in the instructions.
– if the appliance incorporates inductive coupling between two parts that are detachable
from each other, the appliance is supplied from the supply mains with the detachable part
removed.

Part 2-72: Particular requirements for floor treatment machines
with or without traction drive, for commercial use

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
This redline version of the official IEC Standard allows the user to identify the changes made to
the previous edition IEC 60335-2-72:2016. A vertical bar appears in the margin wherever a
change has been made. Additions are in green text, deletions are in strikethrough red text.

IEC 60335-2-72 has been prepared by subcommittee 61J: Electrical motor-operated cleaning
appliances for commercial use, of IEC technical committee 61: Safety of household and
similar electrical appliances. It is an International Standard.
This fifth edition cancels and replaces the fourth edition published in 2016. It constitutes a
technical revision.

INTRODUCTION
It has been assumed in the drafting of this International Standard that the execution of its
provisions is entrusted to appropriately qualified and experienced persons.
This standard recognizes the internationally accepted level of protection against hazards such
as electrical, mechanical, thermal, fire and radiation of appliances when operated as in
normal use taking into account the manufacturer's instructions. It also covers abnormal
situations that can be expected in practice and takes into account the way in which
electromagnetic phenomena can affect the safe operation of appliances.
This standard takes into account the requirements of IEC 60364 as far as possible so that
there is compatibility with the wiring rules when the appliance is connected to the supply
mains. However, national wiring rules may differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
When a part 2 standard does not include additional requirements to cover hazards dealt with
in Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into
consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features that impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of
the requirements and, if found to be substantially equivalent, may be considered to comply
with the standard.

– business premises, for example offices and banks;
– all uses other than normal housekeeping purposes.
These machines may be equipped with a traction drive system. The following power systems
are covered:
– internal combustion engines,
– mains powered motors up to a rated voltage of 250 V for single-phase appliances and
480 V for other appliances,
– battery powered motors.
– battery-operated machines.
Battery powered machines Battery-operated machines may be equipped with a built-in
battery charger.
This standard does not apply to
– floor treatment appliances for household use (IEC 60335-2-10);
– floor treatment machines for commercial use (IEC 60335-2-67);
– spray extraction machines for commercial use (IEC 60335-2-68);

– wet and dry vacuum cleaners, including power brush, for commercial use
(IEC 60335-2-69);
NOTE 103 IEC 60335-2-67, IEC 60335-2-68 and IEC 60335-2-69 cover only machines without traction drive.
– road sweepers;
NOTE 103104 In Europe, EN 13019 covers road sweepers.
– machines designed for use on slopes with a gradient exceeding 20 %;
– machines equipped with a power take-off (PTO);
– machines designed for use in corrosive or explosive environments (dust, vapour or gas);
– machines designed for picking up hazardous dusts (as defined in IEC 60335-2-69),
inflammable substances, or glowing particles;
– machines designed for use in vehicles or on board of ships or aircraft.
NOTE 104105 Attention is drawn to the fact that
– in many countries additional requirements on the safe use of the equipment covered can be specified by the
national health authorities, the national authorities responsible for the protection of labour, the national water
supply authorities and similar authorities;
– ride-on machines designed for transport over public roads can be subject to additional requirements (e.g.
lighting, license plate etc.).

AVANT-PROPOS
1) La Commission Électrotechnique Internationale (IEC) est une organisation mondiale de normalisation
composée de l'ensemble des comités électrotechniques nationaux (Comités nationaux de l'IEC). L'IEC a pour
objet de favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines
de l'électricité et de l'électronique. À cet effet, l'IEC – entre autres activités – publie des Normes
internationales, des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au
public (PAS) et des Guides (ci-après dénommés "Publication(s) de l'IEC"). Leur élaboration est confiée à des
comités d'études, aux travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les
organisations internationales, gouvernementales et non gouvernementales, en liaison avec l'IEC, participent
également aux travaux. L'IEC collabore étroitement avec l'Organisation Internationale de Normalisation (ISO),
selon des conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de l'IEC concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de l'IEC
intéressés sont représentés dans chaque comité d'études.
3) Les Publications de l'IEC se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de l'IEC. Tous les efforts raisonnables sont entrepris afin que l'IEC
s'assure de l'exactitude du contenu technique de ses publications; l'IEC ne peut pas être tenue responsable de
l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d'encourager l'uniformité internationale, les Comités nationaux de l'IEC s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de l'IEC dans leurs publications nationales
et régionales. Toutes divergences entre toutes Publications de l'IEC et toutes publications nationales ou
régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) L'IEC elle-même ne fournit aucune attestation de conformité. Des organismes de certification indépendants
fournissent des services d'évaluation de conformité et, dans certains secteurs, accèdent aux marques de
conformité de l'IEC. L'IEC n'est responsable d'aucun des services effectués par les organismes de certification
indépendants.
6) Tous les utilisateurs doivent s'assurer qu'ils sont en possession de la dernière édition de cette publication.
7) Aucune responsabilité ne doit être imputée à l'IEC, à ses administrateurs, employés, auxiliaires ou
mandataires, y compris ses experts particuliers et les membres de ses comités d'études et des Comités
nationaux de l'IEC, pour tout préjudice causé en cas de dommages corporels et matériels, ou de tout autre
dommage de quelque nature que ce soit, directe ou indirecte, ou pour supporter les coûts (y compris les frais
de justice) et les dépenses découlant de la publication ou de l'utilisation de cette Publication de l'IEC ou de
toute autre Publication de l'IEC, ou au crédit qui lui est accordé.
8) L'attention est attirée sur les références normatives citées dans cette publication. L'utilisation de publications
référencées est obligatoire pour une application correcte de la présente publication.
9) L'attention est attirée sur le fait que certains des éléments de la présente Publication de l'IEC peuvent faire
l'objet de droits de brevet. L'IEC ne saurait être tenue pour responsable de ne pas avoir identifié de tels droits
de brevets.

INTRODUCTION
Il a été considéré en établissant la présente Norme internationale que l'exécution de ses
dispositions était confiée à des personnes expérimentées et ayant une qualification
appropriée.
La présente norme reconnaît le niveau de protection internationalement accepté contre les
dangers électriques, mécaniques, thermiques, liés au feu et au rayonnement des appareils
lorsqu'ils fonctionnent comme en usage normal en tenant compte des instructions du
fabricant. Elle couvre également les situations anormales pouvant être attendues dans la
pratique et prend en considération la manière dont les phénomènes électromagnétiques
peuvent affecter la sécurité de fonctionnement des appareils.
Cette norme tient compte autant que possible des exigences de l'IEC 60364, de façon à
garantir la compatibilité avec les règles d'installation quand l'appareil est raccordé au réseau
d'alimentation. Cependant, des règles nationales d'installation peuvent être différentes.
Si un appareil compris dans le domaine d'application de la présente norme comporte
également des fonctions qui sont couvertes par une autre partie 2 de l'IEC 60335, la partie 2
correspondante est appliquée à chaque fonction séparément, pour autant qu'il est
raisonnable. Si cela est applicable, on tient compte de l'influence d'une fonction sur les autres
fonctions.
Lorsqu'une partie 2 ne comporte pas d'exigences complémentaires pour couvrir les risques
traités dans la Partie 1, la Partie 1 s'applique.
NOTE 1 Cela signifie que les comités d'études responsables pour les parties 2 ont déterminé que des exigences
particulières ne devaient pas être spécifiées pour l'appareil en question en plus des exigences générales.
Cette norme est une norme de famille de produits traitant de la sécurité d'appareils et a
préséance sur les normes horizontales et génériques couvrant le même sujet.
NOTE 2 Les normes horizontales et génériques couvrant un danger ne sont pas applicables puisqu'elles ont été
prises en considération lors du développement des exigences générales et particulières pour la série de normes
IEC 60335. Par exemple, dans le cas des exigences de température de surface pour de nombreux appareils, des
normes génériques, comme l'ISO 13732-1 pour les surfaces chaudes, ne sont pas applicables en plus de la
Partie 1 ou des parties 2.
Un appareil conforme au texte de la présente norme ne sera pas nécessairement jugé comme
satisfaisant aux principes de sécurité de la norme si, lorsqu'il est examiné et soumis aux
essais, il apparaît qu'il présente d'autres caractéristiques qui compromettent le niveau de
sécurité visé par ces exigences.
Un appareil utilisant des matériaux ou présentant des modes de construction différents de
ceux décrits dans les exigences de cette norme peut être examiné et essayé en fonction de
l'objectif poursuivi par ces exigences et, s'il est jugé pratiquement équivalent, il peut être
estimé conforme aux principes de sécurité de la norme.

L'article de la Partie 1 est applicable avec les exceptions suivantes.
3.1.9 Remplacement:
fonctionnement normal
conditions dans lesquelles la machine fonctionne en utilisation normale, telles qu'elles sont
prévues par le fabricant
Elles indiquent la charge correspondant à la puissance assignée ou la charge la plus élevée
susceptible de se présenter parmi toutes les charges particulières résultant des différentes
fonctions qui peuvent être appliquées simultanément, conformément aux instructions du
fabricant. Pour les machines munies d'un siège ou d'une plateforme pour l'opérateur,
l'opérateur est simulé par une masse de 75 kg, solidement maintenue en place à la hauteur
appropriée, dans la position la plus défavorable. Les machines à moteur à combustion interne
sont utilisées avec le combustible spécifié par le fabricant, sauf spécification contraire dans la
présente norme.
Les fonctions opérationnelles comprennent toutes les fonctions de traitement et de conduite.
Fonctionnement de la machine dans les conditions suivantes:
– la batterie est chargée, la batterie étant initialement déchargée de telle sorte que
l'appareil ne puisse pas fonctionner;
– si possible, l'appareil est alimenté par le réseau d'alimentation par le biais d'un chargeur
de batterie autonome, la batterie étant initialement déchargée de telle sorte que l'appareil
ne puisse pas fonctionner. L'appareil est utilisé comme spécifié dans la partie principale
de la présente norme;
– si possible, les chargeurs de batterie intégrés sont connectés au circuit de la
Figure 107. La résistance variable est réglée de telle façon que le courant traversant le
circuit soit égal au courant de sortie continu assigné lorsque le chargeur de batterie est
alimenté à la tension assignée. Lorsque le courant de charge est contrôlé par l'état de
charge de la batterie, la résistance variable et le condensateur sont remplacés par une
batterie déchargée du même type et ayant la capacité maximale spécifiée par les
instructions;
– si l'appareil comprend un couplage inductif entre deux parties qui sont détachables l'une
de l'autre, l'appareil est alimenté par le réseau d'alimentation avec la partie amovible
retirée.
Les conditions de fonctionnement normal relatives aux fonctions opérationnelles sont
spécifiées en 3.1.9.101 à 3.1.9.103:
3.1.9.101 Les machines de brossage et de balayage sont disposées sur une surface de
dalles de pavage en béton précontraint hydrauliquement (voir l'Annexe AA normative) et
mises en fonctionnement par intermittence avec 30 min de marche au moins, suivies de 5 min
d'arrêt.
En guise d'alternative, une surface en béton lisse d'une consistance comparable à celle des
dalles de pavage en béton précontraint hydrauliquement est utilisable.
3.1.9.102 Les machines de polissage et de lustrage à sec sont mises en fonctionnement de
la façon suivante.
Les surfaces en PVC et les surfaces de revêtement de sol similaires sont considérées comme
étant appropriées pour établir les conditions de fonctionnement normal. La crête de
puissance absorbée au cours du processus de séchage du produit chimique utilisé pour
traiter la surface n'est pas considérée comme étant une condition de fonctionnement
normal, mais une moyenne est établie en prolongeant les mesures pendant au moins 10 min.
3.1.9.103 Les shampouineuses pour tapis sont mises en fonctionnement sur une surface
d'essai constituée d'un tapis, conformément à l'IEC TS 62885-1, ce tapis étant fixé au sol.
Avant l'essai, la brosse de la machine est conditionnée en étant mise en fonctionnement
pendant 15 min sur une surface en béton propre et sèche. Après avoir été passée sur la
surface en béton, la brosse est immergée dans une solution de shampoing pendant au moins
30 min.

4 Exigences générales
L'article de la Partie 1 est applicable avec les exceptions suivantes.
Remplacement du premier alinéa par le suivant:
Les machines doivent être construites de façon à fonctionner en toute sécurité et ne
présenter aucun danger pour les personnes ou leur environnement durant une utilisation
normale, même en cas de négligence, et pendant l'installation, le réglage, l'entretien, le
nettoyage, la réparation ou le transport.
Addition:
Pour les besoins de la présente norme, le terme "appareil", tel qu'il est utilisé dans la
Partie 1, doit être compris comme "machine".
5 Conditions générales d'essais
L'article de la Partie 1 est applicable avec les exceptions suivantes.
5.8.1 Addition:
Lorsqu'une tension est mesurée, la valeur de crête de toute ondulation superposée
supérieure à 10 % de la valeur moyenne doit être incluse. Les tensions transitoires sont
ignorées, par exemple une augmentation temporaire de la tension, après avoir débranché la
batterie du circuit de charge.
5.17 Modification:
Il n'est pas nécessaire de soumettre à nouveau à l'essai les chargeurs intégrés conformes à
l'IEC 60335-2-29, sauf pour ceux des Articles 6, 7, 11, 15, 19 et 22.
Il est nécessaire de réévaluer l'Article 29 si le degré de pollution du microenvironnement du
chargeur de batterie est 1 ou 2, à moins que l'isolation ne soit enfermée ou située de sorte
qu'elle ne soit pas susceptible d'être exposée à la pollution produite par la machine en
utilisation normale.
5.101 La solution d'essai doit être stockée dans une atmosphère fraîche et utilisée dans un
délai de sept jours suivant sa préparation.
5.102 Le GVW comprend, si applicable, les réservoirs d'eau propre pleins, les réservoirs
d'eau sale vides (à moitié pleins pour les systèmes de recyclage), les sacs à poussière vides,
la trémie chargée à sa capacité assignée, les plus grosses batteries recommandées, toutes
les options telles que cordons, tuyaux, lances, produits de nettoyage, balais et brosses.
Pour les machines à conducteur porté, est inclus dans le GVW un opérateur normalisé d'un
point de 75 kg.
5.103 Les réservoirs de liquide des shampouineuses et des machines à brosser les sols
mouillés sont remplis jusqu'au niveau le plus élevé indiqué par le fabricant.
5.104 Les machines qui sont conçues pour avoir un sulky sont soumises à essai avec le
sulky supportant le poids d'un opérateur normalisé (75 kg) ou sans le sulky, selon ce qui
correspond à la situation la plus défavorable.
