Metallic and other inorganic coatings — DC magnetron sputtered silver coatings for engineering purposes — Measurement of coating adhesion

This document specifies the test methods for coating adhesion of sputtered silver layer coating for electrical, electronic, optical and other engineering applications. Engineering applications are defined as those in which the coating essentially serves a non-decorative purpose. Although the appearance and serviceability of the sputtered silver coating depends on the condition of the basis material, this document does not specify the condition, finish or surface roughness of the basis material prior to the deposition. Therefore, it is the responsibility of the purchaser to specify the surface finish and roughness of the basis material in order to conform to the product requirements. This document specifies the test methods of coatings on sheets and the flat objects. However, it does not apply to coatings on screw threads, strip or wire in the non-fabricated form.

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).

Introduction
Silver coatings are often specified for their extremely good electrical conductivity for optical, electronic
and electrical engineering applications. Silver coatings for optical and electronic applications have the
minimal thickness of 0,1 µm to 1,0 µm depending on the applications type and demand from customers.
The adhesion test methods of the Ag coatings deposited by DC magnetron sputtering method, given in
this document, are considered to have an adequate accuracy when properly used with test specimens
suitable for the particular method.
The method chosen shall be one which is expected to yield the most reliable results considering the
coating thickness, shape and size of the coating material, the basis material and its roughness, etc.
