ISO 8401:1986, Metallic coatings - Review of methods of measurement of ductility

Applies to coatings of thickness below 200 /um prepared by electroplating, autocatalytic deposition or other processes. The methods of mearuring the ductility can be divided into test on unsupported foils (the foils may consist of one or more metallic layers) and tests of coatings on substrates (with determining the exact point of crack initation of the top layers).
