(Specification)Standard Specification for Appearance of Electroplated Plastic Surfaces
Standard Specification for Appearance of Electroplated Plastic Surfaces
ABSTRACT
This specification limits the amounts and types of visual defects that can be tolerated on decoratively electroplated surfaces of plastic products. The appearance of surfaces will be separately evaluated depending on the prominence of the surface under conditions of ordinary use. The classifications are: surface A; surface B; and surface C. The part under test shall be evaluated in the same relative position as it will normally be viewed under usual conditions of use.
SCOPE
1.1 This specification limits the amounts and types of visual defects that can be tolerated on decoratively electroplated surfaces of plastic products. The quantity of defects permitted shall be specified by the purchaser.
