Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following
URL: www.iso.org/iso/foreword.html.
This document was prepared by the European Committee for Standardization (CEN) Technical
Committee CEN/TC 262, Metallic and other inorganic coatings, in collaboration with ISO Technical
Committee TC 107, Metallic and other inorganic coatings, Subcommittee SC 3, Electrodeposited coatings
and related finishes, in accordance with the agreement on technical cooperation between ISO and CEN
(Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 27830:2008), which has been technically
revised.

1 Scope
This document specifies the technical requirements of metallic and other inorganic coatings in order to
develop consistent technical standards and establishes a standard format for designating the coatings.
It applies to International Standards for electrodeposited, autocatalytic and vapour-deposited coatings.
Detailed technical requirements for individual coatings are not given in this document, but can be
found in the International Standards listed in the Bibliography.
This document does not apply to thermally sprayed and porcelain enamel coatings.

The essential information shall include the following items with cross-references, in parentheses, to the
clauses and sub-clauses that provide further details about the requirements and test methods:
a) the number of the International Standard and the designation as specified in this document (see
Clause 5);
b) the significant surface indicated by drawings or by suitably marked specimens;
c) the nature, condition and finish of the basis material, if they affect serviceability and/or the
appearance of the coating;
d) the tensile strength of the component to enable possible de-embrittlement requirements to be
taken into account;
e) the requirements for heat treatment before and/or after coating, if the requirements are not in
accordance with ISO 9587 or ISO 9588.
4.2 Additional information
Additional information, not included in 4.1, that may be required for a specific coating, product or
application, may include, for example,
a) the appearance required, for example, bright, dull, colour, preferably with samples of the required
finish (if not specified in an applicable ISO Standard);
b) the accepted position(s) on the surface for unavoidable defects, such as jigs, contact marks or areas
in which it is permitted for the coating to be absent;
c) the standards for determining that thickness, corrosion resistance, adhesion, porosity or other
requirements have been met;
d) sampling methods, acceptance levels and inspection requirements for quality control purposes;
e) extra information, for example, packaging or handling instructions or a delivery address shall be
included where relevant.
