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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of 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 www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 107, Metallic and other inorganic coatings,
Subcommittee SC 3, Electrodeposited coatings and related finishes.
This fifth edition cancels and replaces the fourth edition (ISO 1456:2009), which has been technically
revised.
The main changes are as follows:
— new section 5.4 to introduce and explain tables 1 through 4 better including a technical correction to
tables 1 and 2 (remove the possibility to plate Cu10a from a cyanide electrolyte);
— make Table 5 and Annex E consistent;
— updating the requirements for Crmp (minimum and maximum local thickness), introducing requirements
on the number of microdiscontinuities in Crmp, and updating Annex A with an actual overview of
methods to determine microdiscontinuities in Crmp in accordance with DIN 53100 and DIN 53099;
— refer to ISO 16866 for the STEP test and shorten Annex E accordingly;
— make ISO 9227 a normative reference;
— add further explanations to the x-ray spectrometry method in B.3.3 for coating thickness measurement.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.
