This document specifies general methods for measuring the ductility of metallic coatings of thickness below 200 μm prepared by electroplating, autocatalytic deposition or other processes. It is applicable to the following methods: — tests on unsupported foils (separated from the substrate); — tests of coatings on substrates. It does not apply to International Standards that include specific methods of testing for individual coatings. In these cases, the methods specified are used in preference to the methods described in this document and are agreed upon beforehand by the supplier and the purchaser.nd edition 2017-02 Metallic coatings — Review of methods of measurement of ductility Revêtements métalliques — Vue d’ensemble sur les méthodes de mesurage de la ductilité Reference number ISO 8401:2017(E) ？ ISO 2017 ISO 8401:2017(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO 2017, Published in Switzerland All rights reserved.
