2、-M8P18-C2 1. SCOPE These specifications define the performance requirements for interior seating trim fabrics. 2. APPLICATION These specifications were released for materials used as interior seating trim fabrics for the areas of automotive seat cushions, bolsters and inserts, and backs. WSS-M8P18-C
3、1 is defined as a bi-laminate composite with fabric/foam, which could include PE (polyethylene) film added to foam backing for the manufacturing process of sewing and seat builds. WSS-M8P18-C2 is defined as a tri-laminate composite with fabric/foam/backing, which includes backing examples of scrims
4、such as warp or circular knits, or non-woven materials. 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 to testing in a
5、 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 CONSTRUCTION In addition to the requirements listed herein, the face fabric shall meet all requirements of the applicable material sp
6、ecification. The material specification shall take precedence over the performance specification, for any requirement that differs from the performance specification. 3.3.1 Face Fabric, Back Coating, and Scrim construction must be documented in the Material specification. 3.3.2 Fabrics approved unde
7、r C1/C2 and used in other interior applications may need to meet the Applicable Performance specifications such as: Assembly Performance, Instrument Panel and Soft Interior WSS-M15P45-C/latest ENGINEERING MATERIAL SPECIFICATION WSS-M8P18-C1/C2 Copyright 2017, Ford Global Technologies, LLC Page 2 of

18、 manufacture, then bagged in a zipper- or slide-sealed polyethylene (PE) bag, PE-coated aluminum bag or wrapped in aluminum foil prior to bagging. Test specimens shall be cut, then stored in a clean, open environment for 14-28 days. After 14-28 days of air exposure, the specimens shall be tested imm
19、ediately or re-bagged until testing can be performed. Bagged materials or parts must be labelled on the outside of the bag with the following information, and included in the test report: supplier, contact information, product code/trade name or part number, manufacturing location, date of manufactu
20、re, shipping date, start and end dates of conditioning period and test date. Sample shall be tested as part of a production assembly composite if it is 100% bonded. If not 100% bonded, test each component separately. Parts for testing must be labelled with supplier and date of manufacture. 3.10 ODOR
