Watch-cases and accessories. Gold alloy coverings - Determination of fineness, thickness, corrosion resistance and adhesion Ingestion-build-54484What is ISO 3160 2 Gold alloy coverings of watch cases about? Alloys are impurities or mixture of two or more metal compounds. ISO 3160 2 aims to specify coating characterization methods to qualify their corrosion resistance and their adhesion to the substrate concerning esthetical and technical aspects, and to specify methods to determine thickness and gold fineness of these coatings to check that they satisfy the requirements of ISO 3160 1. ISO 3160
