prEN 13042-3:2024 (E)
Introduction
This document is a type-C standard as stated in EN ISO 12100:2010.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e. g. trade unions, organizations for people with special needs);
— service providers, e. g., for maintenance (small, medium and large enterprises);
— consumers (in the case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the Scope of this document.
When requirements of this type-C standard are different from those which are stated in type-A or type-B
standards, the requirements of this type-C standard take precedence over the requirements of the other
standards for machines that have been designed and built according to the requirements of this type-C
standard.
An IS machine is a single purpose machine, reasonably foreseeable misuse is not possible. IS glass
container manufacturing machines within the meaning of this European Standard are machines with
several individual manufacturing sections (Individual Sections = IS) in which the distribution of gobs, the
forming process and the removal of the formed glass container take place automatically. Each
manufacturing section is controlled individually, synchronously with the feeding of the glass gob, by an
electrical linkage. Each section can be isolated individually from the gob distributor and shut down.
The types of processes performed on the IS machine – see also 3.5 –, the operation names of each part of
the process and the names of specific parts of a section are shown in Annex B (informative), Figures B.1
and B.2. For readers’ convenience, a glossary (dictionary) is provided in Annex A (informative).
When compiling this European Standard, it was assumed that due to the heat of the processed material
and the need for the use of auxiliary aids, such as tongs, during work in the danger zone of the closing
mould, there is typically no significant risk from the closing movement of the mould parts during the
normal shaping process of hot glass.
prEN 13042-3:2024 (E)
1 Scope
This document specifies the appropriate technical measures to eliminate or reduce risks arising from
significant hazards during setting, operation, troubleshooting, and maintenance of an IS machine as a
glass forming machine.
This document deals with all significant hazards, hazardous situations, or hazardous events, except for
commissioning, installation, dismantling, and disposal, when it is used as intended and under conditions
of misuse which are reasonably foreseeable by the manufacturer.
It applies to the design and construction of IS machines, including the gob distributor and machine
conveyor.
This document does not deal with gob feeders (see EN 13042-1:2007+A1:2009) and handling machines
for feeding (see EN 13042-2:2004+A1:2009) which are self-standing machines used for the delivery of
portions of melted glass to hollow glass forming machines like glass presses (see
EN 13042-5:2003+A1:2009).
This document is not applicable to the machinery or machinery components manufactured before the
date of its publication.

4 Safety requirements and/or protective/risk reduction measures
4.1 General
Machinery shall comply with the safety requirements and/or protective/risk reduction measures of this
clause. In addition, the machine shall be designed according to the principles of EN ISO 12100:2010 for
relevant but not significant hazards which are not dealt with by this document.
For applications of a B level standard such as EN ISO 14120:2015, EN ISO 4414:2010,
EN ISO 14118:2018, EN ISO 13849-1:2023 and EN 60204-1:2018 and EN ISO 13850:2015, the
manufacturer shall carry out an adequate risk assessment for the requirements thereof where choice is
necessary. This specific risk assessment is part of the general risk assessment relating to the hazards not
covered by this document.
Where the means of reducing the risk is by the arrangement of the installed machine or by a safe system
of work, the manufacturer shall include in the information for use a reference to the reduction means to
be provided, including training, and to any limiting value of the requirement and if appropriate to the
means of verification.
4.2 Mechanical hazards
4.2.1 Guards and indicators
4.2.1.1 Guards for moving transmission parts
The access to moving transmission parts shall be prevented in accordance with EN ISO 14120:2015 and
EN ISO 13857:2019, Table 2.
4.2.1.2 Safety measures for moving parts in the container conveying
Moving parts involved in the container conveying, e.g. conveyor belts, shall be safeguarded in accordance
with EN ISO 14120:2015, Clause 5 and subclauses and EN ISO 14119:2013 when relevant.
4.2.1.3 Safety measures for moving parts involved in the production process
On IS machines in the production process, it is not possible to meet the objectives set by essential health
and safety requirements.
The elements of the equipment shall, as far as possible, be designed and constructed with the purpose of
approaching these objectives.
Guards preventing access to moving parts involved in the forming process shall be designed and
constructed in accordance with EN ISO 14120:2015, Clause 5 and subclauses, if applicable.
Interlocking devices associated with guards shall comply with EN ISO 14119:2013.
4.2.2 Gob distributor and interceptor
4.2.2.1 General
The gob distributor shall be equipped with a gob interceptor that, when actuated, deflects gobs and
prevents gobs from loading into the distributor.
4.2.2.2 Gob distributor and interceptor operation
Controls shall be provided which automatically prevent gob loading into the sections if the gob
distributor fails, e.g. by:
— retraction of the gob distributor from under the glass flow, or
prEN 13042-3:2024 (E)
— insertion of a chute.
To prevent unintended gob loading into the sections a redundant system shall be provided. The
combination of interceptor and gob distributor meet this requirement if the following conditions are
fulfilled:
— unaffected by external energy, e.g. spring-loaded interceptor, diverts the gob into the gob chute;
— gob distributor is in a non-section loading position.
The safety related part of the control system of gob distributor and interceptor shall be at least
performance level c in accordance with EN ISO 13849-1:2023. The boundaries of the control system are
described in EN ISO 12100:2010, Annex A, Figure A.1.
4.2.3 Blank side
At the blank side of each section measures shall be considered to avoid unintended access or to stop
dangerous movements before the parts are reached. An override function is required to perform special
tasks, such as gob loading adjustment, temperature measurement.
If a movable barrier is used, the following requirements apply:
a) In the close position (up position), the section can be operated, and the operator is not allowed to
access.
b) The open position (down position) is only allowed for override functions, activated maintenance
stop, or swabbing cycle.
c) The energy-less position shall be down.
d) The height of the barrier shall be adapted to the type of machine and standard working areas, e.g.
1,4 m based on blank side operator floor level. The width of the barrier shall cover the section with
a maximum gap between the sections of 25 mm.
e) The forming area shall be visible by the operator. If the barrier is meshed, the mesh dimension shall
not exceed 8 mm in diameter or slot width.
f) The force of the movement of the barrier at least to close position (up position) shall be limited to
maximum 150 N or an energy of 10 J. The function of the blank side moveable barrier shall fulfil the
same requirements as the other mechanisms of the section. A special safety performance level for
the control system in accordance with EN ISO 13849-1:2023 is not necessary. By activating
emergency stop or section maintenance stop the blank side barrier moves to the open position (down
position).
NOTE It is assumed that the machine operator uses PPE in the form of gloves.
4.2.4 Blow side
Blow side is adequately secured by the combination of width of conveyor belt and heat-shield together
with the heat radiation, additional safeguarding is not necessary.
4.2.5 Platforms, standing and walking surfaces
Walking surfaces, which are part of IS machines, shall be designed to be anti-slip and minimize the risk
of falling tools, as per EN ISO 14122-2:2016.
prEN 13042-3:2024 (E)
Access to the section on the blow side shall be ensured. This can be achieved by a moveable device, e.g. a
ladder with flat steps and a minimum depth of 75 mm. The ladder shall be equipped with at least one
handrail. The handrail should be changeable between the sides of the ladder.
4.3 Energy supply hazards
4.3.1 Electrical hazards
All electrical equipment shall conform to the requirements of EN 60204-1:2018 in particular with regard
to the protection against electrical shock (see EN 60204-1:2018, Clause 6), e.g. fuses or circuit breakers
and protection against electrical variation, e.g. batteries.
4.3.2 Pneumatical hazards
All pneumatical equipment shall conform to the requirements of EN ISO 4414:2010 in particular with
regard to the protection against pressure variation (see EN ISO 4414:2010, 5.2.2), e.g. isolation valves
and provisions for dissipation of pressure.
4.4 Thermal hazards
4.4.1 General
As far as technically possible the manufacturer shall include measures for reducing the hazards due to
contact with hot surfaces in design and, as because of the nature of the machines these measures will in
general not be sufficient, define working methods, such as use of tongs, warnings and/or necessary
personal protective equipment for protection against the residual risk (see also 6.2, 6.3, 6.4).
4.4.2 Heat-protective equipment against contact and thermal radiation
The IS machine shall be designed to or shall have devices to:
— protect the operator on the blank side from unintended glass drop;
— protect the operator on the blank side from dripping shear spray, water and oil, e.g. by a receiving
hopper for liquids;
— protect the operator at the blow side against contact with hot articles and their thermal radiation
when working over the machine conveyor, e.g. by moveable shields, moveable tunnel-shaped covers.
If the heat protective equipment is not in use it shall be prevented from heat exposure to avoid heating
up.
Control elements shall not be exposed to heat radiation. If this is not possible, control elements shall be
designed taken into consideration that they can be manipulated with PPE.
NOTE Guidance about acceptable contact temperatures can be found in EN ISO 13732-1:2008.
4.4.3 Prevention of fire and fire spread
IS machine shall be designed to avoid accumulation of substances that favors the fire, e.g. cooling liquids,
oils, grease, graphite, etc. and shall be cleaned according to the usage of the machine (see 4.7.1).
The control system of the IS machine shall have an interface to process an external signal coming from
the user in case of fire to stop the machine and auxiliary equipment in a fire safe procedure (see Annex E
“Fire stop procedure”, Figure E.1).
Description of interface signals and behaviour of IS machine shall be documented in the user handbook
and drawings.
prEN 13042-3:2024 (E)
In case of a power failure, necessary movements to stop glass feedings, divert all processed glass from
the IS machine and empty the IS machine shall be possible, e.g. using accumulators for compressed air
and uninterruptible power supply.
4.5 Noise hazards
4.5.1 General principles for noise reduction at source by design
When designing machinery, the information and technical measures to control noise at the source given
in EN ISO 11688-1:2009 shall be considered.
Silencers shall be fitted to either single exhaust points from individual valves or to a common manifold
system.
4.5.2 A-weighted emission sound pressure level determination
Machines shall be designed and constructed so that risks resulting from the emission of airborne noise
are reduced to the lowest level, considering technical progress and the availability of means of reducing
noise, in particular at source. When designing a machine, the available information and technical
measures to control noise at source at the design stage shall be taken into account, see for example
EN ISO 11688-1:2009.
Noise reduction shall be achieved by selecting low noise machine components, e.g. silencers on
inlets/outlets if pneumatic systems are used.
The A-weighted emission sound power level at the workstation in accordance with ISO 11201:2010 or
EN ISO 3744:2010, EN ISO 3746:2010, EN ISO 3747:2010, at least using a method with grade 2 of
accuracy shall be determined. If there are no fixed workstation at the machine, the A-weighted emission
sound pressure level at the noisiest point:
a) in a distance of 1 m from the plunger centre line at the blank side; and
b) in a distance of 1 m from the conveyor centre line at the blow side;
c) and for both measurements in the middle of the machine and in 1,6 m height above top of the
machine bed.
During the measurement, the machine shall be operated without cooling, forming and blowing air,
without glass, without mould and tool equipment and with nominal operating pressures and a cavity rate
of 10 cycles/section/minute at a 12 sections machine.
Operators shall be absent during the measurement.
4.5.3 Information on noise emission
Information on noise emission shall be given by the manufacturer in the instruction handbook, see 6.4.8.
4.6 Ergonomic hazards
4.6.1 General
IS machine shall be designed considering the operator’s characteristics and the activities to be performed
in accordance with EN 614-1:2006+A1:2009, 4.3, EN 614-2:2000+A1:2008 (e.g. A.2.9) and
EN ISO 14122-1:2016.
In particular, the design of IS machine shall consider:
— operator’s body dimensions, posture, movements;
prEN 13042-3:2024 (E)
— provision of appropriate mechanical aids (e.g. hoist), where the physical force to be applied cannot
be kept to a safe level, to avoid musculoskeletal overloads;
— reduction of repetitive activities through mechanization and automation when possible;
— exposure to heat radiation and conduction;
— The controls shall be designed in accordance with ISO 6385:2016, 3.6.6 (e.g. buttons shall be
designed to push them with PPE or manual override).
— If the intensity of the normal lighting of the environment is not sufficient the machine shall be
equipped with a lighting system to provide sufficient illumination of the working areas, according to
EN 1837:2020, and EN 12464-1:2021.
4.6.2 Means of access to the mould equipment
Blank and blow sides of the IS machine shall be equipped with suitable means of access to reach the
internal parts of the section, in accordance with EN ISO 14122-1:2016, EN ISO 14122-2:2016,
EN ISO 14122-3:2016.
4.6.3 Hoist
4.6.3.1 General
The design of the IS machine shall allow the use of hoist, at least for handle load heavier than 15 kg.
To prevent musculoskeletal disorder by handling of parts with a mass higher than 15 kg, measures shall
be considered. This can be:
— installation of a power-driven handling system, or
— installation of lifting points to connect a lifting equipment.
If the use of a hoist is not possible, e.g. for changing delivery system parts, the handling of the parts by at
least two people shall be possible.
4.6.3.2 Handling of delivery system
The design of the delivery system parts requires handling by two people.
To prevent musculoskeletal disorder by handling of parts with a mass higher than 15 kg, measures shall
be considered. This can be:
— installation of a power-driven handling system, or
— installation of lifting points to connect a lifting equipment.
If this is not possible, it is at least necessary to provide enough space to handle the parts.
A secure position is necessary to exchange delivery system parts.
4.6.4 Mould swabbing procedures
Each section shall be designed with a function to allow mould swabbing in a controlled manner. The ready
to swab status shall be indicated to the operator.
prEN 13042-3:2024 (E)
4.7 Hazards associated with the material used
4.7.1 Cleaning of the machines
IS machines shall be designed to allow easy and safe cleaning from any contaminant, e.g. by mechanical
cleaning or vacuum cleaning.
4.8 Cyber security
4.8.1 Protection against corruption
Will be added in the near future.
4.9 Combination of hazards/Interferential risk
4.9.1 Setting operation for any mechanisms
To prevent interferential risk between several operators, any movements based on actions from other
operators shall be avoided, e.g. by separate valve blocks or interlocked/visible mechanical blockings.
4.10 Starting equipment, unexpected start-up and stopping equipment
4.10.1 Starting equipment
Starting equipment shall be provided for each individual section. The manual controls (actuators) shall
be fitted at the respective section.
Starting equipment for the automatic working cycle of an individual section shall be fitted and configured
or arranged in each section. The starting equipment of the forming section shall be placed at least on the
blank side. Appropriate control devices with two push buttons to be pressed at the same time shall be
used and shall initiate intermitted green lights visible on both sides of the section until the section starts.
After the section has started, the lights are permanently illuminated. The minimum distance between the
two push buttons shall be at least 260 mm.
The gob distributor and machine conveyor start switches and height adjustment controls for machine
conveyor shall be positioned so that the operator has a complete overview of the respective area.
Ancillary devices potentially causing a risk of hazard shall follow the same principle.
Indicator devices shall be used to identify the main switching states, e.g. “ready to be started”, “start
phase”, “individual operation/automatic operation”, “disconnection from the electronic control” (see e.g.
EN 60204-1:2018, 10.3).
4.10.2 Prevention of an unexpected start-up (maintenance stop)
Each individual section shall be equipped on blank and blow sides with a maintenance stop device in
accordance with EN ISO 14118:2018.
The maintenance stop shall override every function of the section.
The maintenance stop shall prevent unintentional start of any hazardous situation (e.g. movements,
cooling air) of the respective section side and the delivery of gobs into this section. Manual activation of
pneumatic valves at the section is not affected.
The gob distributor, the conveyor, and the additional equipment shall also be equipped with maintenance
stop devices.
The safety-related parts of the control system for the maintenance stop function shall be at least in
accordance with EN ISO 13849-1:2023 performance level c (see also 6.4.5 to 6.4.11).
Unlocking the device shall not cause the section to start up.
prEN 13042-3:2024 (E)
4.10.3 Stopping equipment
4.10.3.1 General
On all places where starting equipment is installed also stopping equipment is necessary. The stopping
function has the priority on all operating functions.
The normal stop function of the machine can be achieved by operational stops from all single control
panels in sequence with maintenance stops.
Stopping functions (normal stop, maintenance stop, and emergency stop) shall be of category 0 or
category 1 in accordance with EN 60204-1:2018, and in accordance with EN ISO 14118:2018 and
EN ISO 13850:2015. Operational stop shall be of category 2.
4.10.3.2 Emergency stop equipment
