Table 2 - Average thickness of classes of gold coating

Defines the following criteria for cutlery which is gold plated: Performance criteria for table cutlery such as knives, forks, spoons, ladles, carving sets, and other pieces; composition limits for base metals; tests for resistance to deformation, blade hardness, handle attachment firmness, corrosion resistance and adhesion and thickness of gold coating; three minimum thicknesses of gold plating- first, second and third class.
