APPLICATION This specification was released for material used for accessory floor mats applications on 2003 Ford vehicles. 3. REQUIREMENTS In addition to the requirements listed herein, the end-item carpet

4、assembly (molded or otherwise fabricated) shall meet all requirements of the WSS-M15P44-A performance specification for accessory floor mat applications. 3.1 QUALITY SYSTEM REQUIREMENTS Material suppliers and part producers must conform to Quality System Requirements, QS-9000. Material specification

5、 requirements are to be used for initial qualification of materials. A Control Plan for ongoing production verification is required. This plan must be reviewed and approved by the relevant Ford Materials activity and/or Ford Supplier Technical Assistance (STA) prior to production parts submission. A

6、ppropriate statistical tools must be used to analyze process/product data and assure consistent processing of the materials. Material specification requirements are to be used for initial qualification of materials. 3.1 QUALITY SYSTEM REQUIREMENTS Material suppliers and part producers must conform t

7、o the Companys Quality System Requirements. ENGINEERING MATERIAL SPECIFICATION WSS-M3H128-A2 Page 2 of 5 Copyright 2008, Ford Global Technologies, Inc. 3.2 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS IR spectra and thermograms established for initial approval shall constitute the reference st

8、andard and shall be kept on file at the designated material laboratory. All samples shall produce IR spectra and thermograms that correspond to the reference standard when tested under the same conditions. 3.3 CONDITIONING AND TEST CONDITIONS All test values indicated herein are based on material co

9、nditioned in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5 % relative humidity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified. 3.4 SAMPLE SELECTION All evaluations shall be conducted on test specimens taken from finished roll goods prior

10、to any subsequent operations, such as reheating or molding. 3.5 APPEARANCE (FLTM BI 109-01) The color, pattern, and finish shall match the approved Design Center master sample, or shall be specified on the engineering drawing. 3.6 COMPOSITION (ASTM D 276) Pile Yarn Nylon 66 Primary Foundation Materi
