SCOPE The material defined by this specification is an impact modified, heat stabilized polyamide 6 (nyl

3、on 6) molding compound. 2. APPLICATION This specification was released originally for material used for parking brake cable seals. NOTICE: This material absorbs and retains moisture. Part design and tolerances must accommodate changes in part dimensions and physical properties due to moisture absorp

4、tion or loss in the service/assembly environment. Information on this material with respect to moisture should be obtained from the responsible PEO Materials Engineering Department. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform

5、to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 HEAT STABILIZER ADDITIVE Ford Motor Company, at its option, may conduct the following heat stabilizer additive test on material/parts supplied to this specification. The stabilizer must be present. Test Solution: To

6、 a 10 mL ground glass stoppered graduate add 0.5 mL glacial acetic acid, 1.5 mL of 3% hydrogen peroxide solution (fresh) and a 1 mL of carbon tetrachloride. Procedure: Place 20 g of polyamide pellets and 40 g of distilled water in a beaker. Allow the water to boil gently for 5 minutes. Decant off th

7、e water into another beaker. Add 7 mL of this decanted water to the test solution and shake the mixture vigorously for about 15 s. If the carbon tetrachloride which settles on the bottom is purple, the heat stabilizer system is present. 3.3 CONDITIONING AND TEST CONDITIONS All test values indicated

8、herein are based on material and specimens with moisture content not exceeding 0.3% (test according to ASTM D 789). All test materials immediately after processing have to be sealed in containers that are impermeable to water vapor. If the moisture content exceeds 0.3%, condition the material for a

9、minimum of 16 h at 40 - 50 C at a reduced pressure below 133 Pa. Conduct tests in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5% relative humidity. Individual specimens shall not be removed from closed containers until immediately before testing. ENGINEERING MATERIAL SPECIFICATIONESA-M4D430-A P
