10、 Ford Motor process (SREA). 3.1.5 Dry as molded: All test values indicated herein are based on material and specimens with moisture content not exceeding 0.2% except where noted (Moisture Conditioned, see paragraph 3.1.5) (test according to ISO 15512 Method B/ASTM D 6869). All test materials have to
11、 be sealed in moisture-proof containers and stored at 23 +/- 2 C for at least 24 h immediately after processing. If the moisture content exceeds 0.2%, conditioning 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
12、C and 50 +/- 5% relative humidity. Individual specimens shall not be removed from closed containers until immediately before testing. 3.1.6 Moisture Conditioned: The specimens shall be conditioned to a moisture content of 1.0 to 2.0 wt% moisture then place the specimens in standard atmosphere of 23
13、+/- 2 C and 50 +/- 5% relative humidity for at least 1 h before testing (according to ISO 1110). Moisture content shall be reported to verify the moisture level. . 3.1.7 Performance Criteria: Parts using these specifications must comply with all the requirements of WSS-M15P50-B/Latest and fulfill ap
