SCOPE The material defined by this specification is the minimum durability and performance requirements of all enclosed carpeted luggage or load compartment trim components where various materials
2、are combined to provide a trim assembly having decorative and/or functional features. This includes: rear seat back trim in enclosed luggage compartment applications, deck lid trim and spare tire covers (not for exposed load compartment applications). 2. APPLICATION This specification was released o
3、riginally for material used as enclosed luggage compartment trim parts. 3. REQUIREMENTS 3.1 APPROVED SOURCES This specification is performance based and does not have approved sources. 3.2 CONDITIONING AND TEST CONDITIONS All test values are based on material conditioned for not less than 24 h prior
4、 to testing in a controlled environment of 23 +/- 2 C and 50 +/- 5% relative humidity. Testing of the material should occur in the conditioning environment or soon after removal. 3.3 PERFORMANCE CRITERIA 3.3.1 In addition to the requirements listed herein, the individual carpet assembly components s
5、hall meet all the requirements of the applicable material specifications for the carpet, padding, adhesive, barrier, or trim application as well as any functional/SDS requirements as outlined by Engineering. Material specification requirements are to be used mainly for initial qualification of mater
6、ials. 3.3.2 Mold in Color plastic components shall meet the requirements of WSS-M15P4-G/latest. 3.3.3 Painted components shall meet the requirements of WSS-M2P188-B1/latest for paint over plastic or WSS-M2P190-A / latest if paint over metal. 3.3.4 Labels must meet the appropriate suffix of WSS-M99P4
