This part of ISO 3160<\/span> <\/span> specifies methods to determine fineness, thickness, corrosion resistance and adhesion for gold alloy coverings on watch-cases and accessories, including bracelets when they are permanently attached to the case.<\/p>\n

The tests apply only to significant surfaces.<\/p>\n

This part of ISO 3160<\/span> <\/span> applies to all gold alloy coverings specified in ISO 3160\u20111<\/span> <\/span>.<\/p>\n
