Metallic coatings - Review of methods of measurement of ductility

ISO 8401:2017 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.
