SCOPE The material defined by this specification is a heat stabilized 15% glass fiber and 25% mineral reinforced polyamide 66 molding compound. 2. APPLICATION This specification was released

3、originally for material used for engine cooling fan and fan shroud. 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 environment. 3. REQUIREMEN

4、T 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). 3.3 CONDITIONING AND TEST CONDITIONS All test values indicated herein are based on material and specimens with mois

5、ture content not exceeding 0.2% (test according to ISO 960, Method B/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 0.2%, condition the material for a minimum of 16 h at 40 - 50 C at a

6、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. 3.4 MOLDING COMPOUND 3.4.1 Glass Fiber/Mineral Content 36 - 42% (ISO 3451/4, test
