SCOPE The material defined by this s

2、pecification is any flexible (soft) cover fabric, or laminate, to be bonded to an interior roof system substrate base or interior part above the belt line. This includes applications such as headliner, pillar, sun visor, roller shade, and moon/sun roof. 2. APPLICATION This specification was released

3、 originally for all materials (not including polymeric films) used for soft interior cover stock such as headliner, pillar, sun visor, roller shade and moon/sun roof, which includes knits, woven or non-woven construction. This includes any combination of composites with foam, scrim or fabric that is

4、 applicable to the part assembly. In addition, applicable system requirements that must be met are: Headlining Performance WSS-M15P27-F/latest Sun Visor Performance WSS-M98P3-B/latest Interior Wrapped Components- WSS-M15P45-B/latest Polyurethane Foam Performance WSS-M99P48-A1-A3/latest Testing must

5、be conducted according to Table 1 for each approval phase with the appropriate backing for the application. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS 3.1.1 Material suppliers and part producers must conform to the Companys Standard Requirements for Production Materials (WSS

6、M99P1111-A/latest). 3.1.2 Vehicle Interior Environment Quality Materials/Component Performance Requirements Materials used in interior applications must meet the requirements outlined in WSS-M99P2222-D1/latest. 3.2 CONSTRUCTION Face fabric shall be specified in the individual material specification.

7、 Backing materials to face fabric (scrim, foam or coatings) should be applied as required to meet application and process requirements and should be present for composite approval. 3.3 APPEARANCE The color, pattern, finish and hand shall match the approved Corporate Design master sample.
