2、1 of 15 ASSEMBLY PERFORMANCE, INSTRUMENT PANEL AND SOFT WSS-M15P45-C INTERIOR COMPONENTS, FLEXIBLE COVER SKIN MATERIAL 1. SCOPE The material defined by this specification is an instrument panel assembly, instrument panel component, floor console armrest, valence panel, steering wheel airbag cover, h

3、ush panel, door panel or wrapped pillar, which utilizes a flexible (soft) cover skin material over a hard substrate with or without foam or spacer fabric, and with or without a topcoat. 2. APPLICATION This specification was released originally for material used for all soft interior components, not

4、including seat trim covers, molded/foam-in-place armrests and headrests. This specification includes top-coated (added for gloss control, haptics and/or cleanability) and in-mold coated (IMC) skins. Instrument panels containing an integrated airbag system must also meet any additional specifications

5、 on the Engineering Document. All painted flexible cover skins (through a secondary process) shall meet the requirements of WSS-M2P188-B1/latest. All soft skins or fabrics for armrests and door panels must also meet the requirements of WSS-M8P3-E1/E2/E3/latest (flexible polymeric films), WSS-M99P43-

6、C/latest (leather) or WSS-M8P18-B1/B2/B3/B4/latest (fabrics). EXCLUDED The following applications are excluded from this specification. hard instrument panels, hard door panels, finish panels (WSS-M15P4-Glatest) package trays (WSS-M15P6-E/latest) steering wheels (WSS-M98P12-B/latest) headliners (WSS
