5、ucers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.1.1 Many 4D resin specifications prior to 2011, identified certain requirements with the symbol (s), which indicated that the mean and +/- 3 sigma values were to be reported. The specification minim
6、um, maximum or range was established using 3 sigma values. For 2011 and beyond, refer to Table 1 for number of samples required for each test. 3.1.2 Dry as molded: All test values indicated herein are based on material and specimens with moisture content not exceeding 0.2% except where noted (Moistu
7、re Conditioned) (test according to ISO 15512 Method B/ASTM D6869). All test materials have to 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
8、 C at a reduced pressure below 133 kPa. Conduct tests in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5% relative humidity.
