SCOPE The materials defined by these specifications are fine denier, bulked continuous filament (BCF) nylon, cut pile carpets, tufted
4、 into a synthetic primary foundation. WSS-M3H115-A is coated with a polyethylene backcoating and a secondary backing. WSS-M3H115-A2 is coated with a latex backcoating. WSS-M3H115-A3 is precoated. The precoated carpet is then laminated to a barrier material for improved fit and acoustical properties.
5、 WSS-M3H115-A4 is coated with a polyethylene backcoating. 2. APPLICATION WSS-M3H115-A was released originally for material used as a floor covering for the 1997 Escort. WSS-M3H115-A2 was released originally for material used on accessory mats. WSS-M3H115-A3 was released originally for material used
6、as a floor covering for the 1999 Mustang. WSS-M3H115-A3 was released originally for material used as a floor covering and for trim parts. 3. REQUIREMENTS In addition to the requirements listed herein, the end-item carpet or mat assembly (molded or otherwise fabricated), shall meet all applicable per
7、formance specifications and/or requirements specified on the engineering drawing. 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A).
