2、3 NYLON/POLYPHENYLENE OXIDE ALLOY, PAINTABLE ESB-M4D545-A 1. SCOPE The material defined by this specification is an amorphous polyphenylene oxide polymer reinforcement of a crystalline polyamide (nylon). 2. APPLICATION This specification was released originally for material used for painted mirror h
3、ousings and plastic fender applications. 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. Information on this material with respec
4、t 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 For Production Materials (WSS-M99P1111-A). 3.3 CONDI
5、TIONING AND TEST CONDITIONS All test values indicated herein are based on material and specimens with moisture content not exceeding 0.2% (test according to ISO R 960, Method B/ASTM D 789). All test materials immediately after processing have to be sealed in containers that are impermeable to water
6、vapor. If the moisture content exceeds 0.2%, condition the material for a minimum of 16 h at 40 - 50 C at a reduced pressure below 133 kPa. 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 i
7、mmediately before testing. 3.4 MOLDED TEST SPECIMEN 3.4.1 Preparation of Test Specimens All test specimens shall be injection molded in accordance with ISO 294/ASTM D 1897. The values of this specification are based on injection molded specimens unless otherwise specified. 3.4.2 Density 1.05 - 1.15
