SCOPE The material defined by this specification is a heat stabilized flexible type 6 nylon, suitable for extrusion applications. 2. APPLICATION This specification

3、was released originally for material used as an outer jacket for transmission shift cables. NOTICE: This material absorbs and retains moisture. Part design and tolerances must accommodate changes in part dimensions and physical properties due to moisture absorption or loss in the service/assembly en

4、vironment. 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 to the Companys Standard Requirements F

5、or Production Materials (WSS-M99P1111-A). 3.2 HEAT STABILIZER ADDITIVE Ford Motor Company, at its option, may conduct following heat stabilizer additive test on material/parts supplied to this specification. The stabilizer must be present as determined by one of the following tests: Test Method A: T

6、o 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. Place 20 g of nylon pellets and 40 g of distilled water in a beaker. Allow the water to boil gently for 5 min. Decant off the water into anoth

7、er beaker. Add 7 mL of this decanted water to the previously prepared 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. Test Method B: Place 20 g of nylon pellets and 50 g of distil

8、led water in a beaker. Allow the water to gently boil for five minutes. Decant the water into another beaker. Add 40 mL of this decanted water to a 50 mL ground glass stoppered graduate. Add while stirring 3 mL of nitric acid, two drops of 1 N potassium permanganate solution, and 7 mL of carbon tetr

9、achloride. Shake the mixture vigorously for about 15 s. If the carbon tetrachloride, which settles to the bottom, is brown or purple, the heat stabilizer additive is present. 3.3 MOLDING COMPOUND 3.3.1 Melting Point 210 - 225 C (ASTM D 789) ENGINEERING MATERIAL SPECIFICATIONESA-M4D331-APrinted copie
