APPLICATION This specification was released originally for material used for full floor applications on 2003 Ford vehicles. 3. REQUIREMENTS In addition to the requirements listed herein, the end-item carpet assembly (molded or o

4、therwise fabricated), shall meet all requirements of the WSS-M8P16-A performance specification for full floor applications. Material specification requirements are to be used for initial qualification of materials. 3.1 QUALITY SYSTEM REQUIREMENTS Material suppliers and part producers must conform to

5、 the Companys Quality System Requirements. 3.2 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS IR spectra and thermograms established for initial approval shall constitute the reference standard and shall be kept on file at the designated material laboratory. All samples shall produce IR spectra

6、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 conditioned in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5 % relative humidity for not less than 24 h pr

7、ior to testing and tested under the same conditions unless otherwise specified. ENGINEERING MATERIAL SPECIFICATION WSS-M3H128-A Page 2 of 4 Copyright 2008, Ford Global Technologies, Inc. 3.4 SAMPLE SELECTION All evaluations shall be conducted on test specimens taken from finished roll goods prior to

8、 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 Material
