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
