2、ologies, LLC Page 1 of 10 PERFORMANCE, ROOF SYSTEMS FABRIC, INTERIOR WSS-M8P27-B1 1. SCOPE The material defined by this specification 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 applicati

3、ons such as headliner, pillar, sun visor, roller shade, and moon/sun roof. 2. APPLICATION This specification was released 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 includ

4、es knits, woven or non-woven construction. This includes any combination of composites with foam, scrim or fabric that is applicable to the part assembly. Testing must be conducted according to Table 1 for each approval phase with the appropriate backing for the application. 3. REQUIREMENTS 3.1 APPR

5、OVED SOURCES This specification is performance based and does not have approved sources 3.2 PERFORMANCE SPECIFICATION For lamination requirements refer to Performance Lamination for Seating and Interior Trim Specification WSS-M8P30-A1.
