This specification covers the performance requirements of instrument panels, consoles, door trim, quarter trim panel, garnish moldings, armrests, headrests, assist handles, rear window trim panel and seat trims. This specification replaces, but does not supersede, GM2740M, GM2741M, GM2797M, GM7454M, and GM2739M.

Some interior components may be covered under other part performance specifications. For example, the overhead system panel is covered by GM2745M, floor carpeting systems by GM2715M and molded trunk systems by GM2750M. These specs were not incorporated into this specification due to the considerable amount of unique test parameters and material characteristics. Additionally, GM7451M should be used to specify the performance requirements for simple, molded-in-color or painted plastic components, which are not sourced as part of the complex system.

It is intended that this performance specification be used for interior parts with appearance attributes (color, grain and / or gloss designation) in conjunction with the appropriate GM raw material specification for UV stabilized materials. These can be in formats such as GMP.XXX.XXX or GMNXXXX for plastics, 998XXXX or GMNXXXX for paint, GMXXXXM or GMWXXXX for textiles and other general materials. Additionally, GM7001M/GM7400M callouts or other appropriate industry standard specifications may be used.
