REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS 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 conduc

5、t following heat stabilizer additive test on material/parts supplied to this specification. The stabilizer must be present. Test Method: Ash 1 g sample in a covered porcelain crucible (size 17 H is suitable) using a muffle furnace at a temperature of 500 520 C. Be certain temperature does not exceed

6、 530 C. Overheating will volatilize the stabilizer. Allow the crucible to cool to room temperature and then add 1 - 2 Ml of 5 molar hydrochloric acid, swishing to wash sides of crucible with acid. Evaporate to dryness, preferably on a steam bath or by very gentle heating with a low flame. Do not ove

7、rheat. Dissolve the stabilizer by warming in 3 - 4 drops of distilled water. Note: Greenish yellow color may occur at this point, which indicates the presence of a heat stabilizer. If the color does not occur, proceed as follows. Withdraw by means of a capillary tube and place on a piece of #40 What

A faint greenish yellow color indicates the presence of a heat stabilizer. It is imperative to use con
