Bibliography

Describes 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.

This part of ISO3160 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. The tests apply only to significant surfaces. This part of ISO3160 applies to all gold alloy coverings specified in ISO3160‑1 .
