scope:

This test method provides a procedure to evaluate raw ABS moldings for surface stress, rubber dispersion in the surface, and internal stress. This is not a quantitative test and should be used only for identifying and correcting serious stress or rubber distribution problems in raw ABS moldings. It is based on American S ociety of Electroplated Plastics Test Procedure 203.

Restricted Chemical Substances

All product supplied to the requirements of this specification must comply with the requirements of the MPAPS B-50 specification.

APPLICATION

This method is for qualitatively evaluating the stress state of test panels or production parts, before being plated to ensure durability of material after plating. It applies to ABS-based molded plastic parts that are to be decorative electroplated with chromium for both interior and exterior use Per MPAPS G- 7051. Example parts are exterior grilles, light bezels, nameplates, interior ornaments, knobs, and the like.
