2、DING COMPOUND NOT TO BE USED FOR NEW DESIGN 1. SCOPE The material defined by this specification is an impact modified type 66 polyamide molding compound filled with 15 % PTFE powder and 30 % glass fiber. 2. APPLICATION This specification was released originally for material used for floater bracket.
3、 3. REQUIREMENTS 3.1 QUALITY SYSTEM REQUIREMENTS Material suppliers and part producers must conform to Quality System Requirements, QS-9000. Material specification requirements are to be used for initial qualification of materials. A Control Plan for ongoing production verification is required. This
4、 plan must be reviewed and approved by the relevant Ford Materials activity and/or Ford Supplier Technical Assistance (STA) prior to production parts submission. Appropriate statistical tools must be used to analyze process/product data and assure consistent processing of the materials. Part produce
5、rs using this material in their products, must use Ford approved materials and must conform to a process control plan which has been approved by STA and/or the relevant Materials Activity. 3.1.1 All requirements of this specification, identified by symbol (s), shall be met with data representing 3 s
6、igma values. 3.2 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS Ford Motor Company, at its option, may conduct 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 standar
7、d 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.
