SCOPE The material defined by WSD-M3H64-C is a polyamide cut pile, velour, tufted carpet with polyethylene resin backcoating and a protection pad on the drivers side. 2. APPLICATION This specification was released originally for material used as a passenger compa
3、rtment floor covering. 3. REQUIREMENTS Unless otherwise specified herein, this material must meet the requirements of WSD-M8P16-A. 3.1 STATISTICAL PROCESS Suppliers must conform to the requirements of Ford Quality System Standard Q-101. A mutually acceptable Control Plan as described therein is requ
4、ired for material/source approval. Appropriate statistical tools must be used to analyze process/product data so that variation in the final product is continuously reduced. 3.2 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS Ford Motor Company, at its option, may conduct infrared and/or thermal
5、analysis of material/parts supplied to this specification. The 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 and thermograms that correspond to
6、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 prior to testing and tested under the
7、 same conditions unless otherwise specified ENGINEERING MATERIAL SPECIFICATION WSD-M3H64-C 3.4 SAMPLE SELECTION All evaluations shall be conducted on test specimens taken from finished components. 3.5 APPEARANCE (FLTM BI 109-01) The color, pattern, and finish shall match the approved Design Center m

11、lent in all characteristics to the material upon which approval was originally granted. ENGINEERING MATERIAL SPECIFICATION WSD-M3H64-C Prior to making any change in the properties, composition, construction, color, processing or labeling of the material originally approved under this specification,
12、whether or not such changes affect the materials ability to meet the specification requirements, the Supplier shall notify Purchasing, Toxicology and the affected Materials Engineering activity of the proposed changes and obtain the written approval of the Materials Engineering activity. Test data,
13、test samples and a new code identification are to be submitted with the request. Substance restrictions imposed by law, regulations or Ford, apply to the materials addressed by this document. The restrictions are defined in Engineering Material Specification WSS-M99P9999-A1. 4. APPROVAL OF MATERIALS
14、 Materials defined by this specification must have prior approval by the responsible Materials Engineering activity. Suppliers desiring approval of their materials shall first obtain an expression of interest from the affected Purchasing, Design and Materials Engineering activity. Upon request, the
15、Supplier shall submit to the affected Materials Engineering activity a completed copy of their laboratory test reports, signed by a qualified and authorized representative of the test facility, demonstrating full compliance with all the requirements of this specification (test results, not nominal v
16、alues), the material designation and code number, and test specimens for Ford evaluation. Fords engineering approval of a material will be based on its performance to this specification and on an assessment of suitability for intended processes and/or applications. Upon approval, the material will b
