This document specifies general methods for measuring the ductility of metallic coatings with a thickness of less than 200 m applied by electrodeposition, autocatalytic deposition or other methods. It is applicable to the following two procedures:
——Tests on free films (lifted off the substrate);
——Tests of coatings on substrates. It does not apply to international standards that contain special test procedures for individual coatings. In these cases, the established procedures previously agreed between the supplier and the purchaser are preferred to the procedures set out in this document.
