2、, LLC Page 1 of 3 NYLON (TYPE 6), HEAT STABILIZED ESF-M4D101-A NOT TO BE USED FOR NEW DESIGN 1. SCOPE The material defined by this specification is a type 6 nylon molding compound, heat stabilized against degradation at elevated temperatures. 2. APPLICATION This specification was released originally

3、 for material used for light service load gears, bearings, grommets, spacers, and other similar parts where temperatures may be as high as 110 C continuously, or up to 149 C intermittently. NOTICE: This material absorbs and retains moisture. Part design and tolerances must accommodate changes in par

4、t dimensions and physical properties due to moisture absorption 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 MA

5、TERIALS Material suppliers and part producers must conform 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 speci

6、fication. The stabilizer must be present as determined by one of the following tests: Test Method A: To 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 d

7、istilled water in a beaker. Allow the water to boil gently for 5 min. Decant off the water into another 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,

8、 the heat stabilizer system is present. Test Method B: Place 20 g of nylon pellets and 50 g of distilled 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 st

9、irring 3 mL of nitric acid, two drops of 1 N potassium permanganate solution, and 7 mL of carbon tetrachloride. 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. ENGINEERING MATERIAL SPE
