SCOPE The material defined by this specification is a polypropylene 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 pa

3、ssenger compartment floor covering. 3. REQUIREMENTS In addition to the requirements quoted 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

4、described therein is required 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

5、 infrared and/or thermal 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 thermo

6、grams 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 prior to tes

7、ting and tested under the same conditions unless otherwise specified. ENGINEERING MATERIAL SPECIFICATION WSD-M3H99-A WP 3948-b Page 2 of 4 3.4 SAMPLE SELECTION All evaluations shall be conducted on test specimens taken from finished roll goods prior to any subsequent operations, such as reheating or

8、 molding. 3.5 APPEARANCE (FLTM BI 109-01) The color, pattern, and finish shall match the approved Design Centre master sample, or shall be as specified on the engineering drawing. 3.6 CONSTRUCTION (ASTM D 1244) Fibre 15 dtex polypropylene 3.7 COMPOSITION (ASTM D 276) 3.7.1 Pile 100 % polypropylene,

10、eels) After testing, the specimen must not show any greater signs of deterioration than the sample originally approved by the Materials Engineering Activity. 3.10 FLAMMABILITY (ISO 3795/SAE J369) Burn Rate, max 100 mm/minute 3.11 ADDITIONAL REQUIREMENTS Specific requirements for material and/or manu

11、factured parts shall be specified on the Engineering drawing, Engineering parts specification and/or performance specifications. All critical areas with respect to these properties shall be clearly designated on the engineering drawing. ENGINEERING MATERIAL SPECIFICATION WSD-M3H99-A WP 3948-b Page 3

12、 of 4 3.12 SUPPLIERS RESPONSIBILITY All materials supplied to this specification must be equivalent in all characteristics to the material upon which approval was originally granted. Prior to making any change in the properties, composition, construction, color, processing or labeling of the materia

13、l originally approved under this specification, 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

14、 the Materials Engineering activity. Test data, 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 Specifi

15、cation WSS-M99P9999-A1, unless a different suffix (e.g., A2 or A3) is specified on the engineering document for the application. 4. APPROVAL OF MATERIALS Materials defined by this specification must have prior approval by the responsible Materials Engineering activity. Suppliers desiring approval of

16、 their materials shall first obtain an expression of interest from the affected Purchasing, Design and Materials Engineering activity. Upon request, the Supplier shall submit to the affected Materials Engineering activity a completed copy of their laboratory test reports, signed by a qualified and a

17、uthorized representative of the test facility, demonstrating full compliance with all the requirements of this specification (test results, not nominal values), the material designation and code number, and test specimens for Ford evaluation. Fords engineering approval of a material will be based on

18、 its performance to this specification and on an assessment of suitability for intended processes and/or applications. Upon approval, the material will be added to the Engineering Material Approved Source List. ENGINEERING MATERIAL SPECIFICATION WSD-M3H99-A WP 3948-b Page 4 of 4 5. GENERAL INFORMATI
