This specification supercedes all prior regional specifications for interior paint performance for the General Motors Corporation. This specification encompasses interior physical, environmental and chemical durability requirements for all interior coatings. These coating systems can be metallic or non-metallic colors in both hard and soft haptic technologies. Coatings covered by this specification can be applied to plastic substrates, flexible substrates, rigid substrates or integral skin foam systems.

The extended durability testing in this specification is required for corporate approval of all new interior paints. The requirements listed in this specification must be met by all paint systems used in GM vehicle interiors. This specification may be used to generically qualify red and blue colored paints for global paint technology approval or it may be used to qualify paints in production colors for use only on specific vehicle applications. Only when a paint system is generically approved on a specific plastic, will the paint system be approved to the appropriate interior paint specification and entered into MATSPC. Once MATSPC approval is granted to a new paint system on a given class of plastics, APOPS testing (validation testing of parts painted in vehicle colors), will be required to complete the approval on that part. The approved paint system will then be entered into the Approved Paint on Plastic Systems (GM APOPS) data base or documented through written approval from responsible GM Materials Engineering department. The test requirements for APOPS testing will be found in Appendix A

Note: In the case where parts are fabricated from pre-painted material, the paint film shall be capable of withstanding all the necessary fabrication processes, including forming stresses and temperatures, in addition to specified requirements as detailed in this specification.
