See Table 1. 4 TEST PROCEDURES. 4.1 Test specimens shall be injection molded per IS0 29411, as described in SAE J1639, unless otherwise specified. 4.2 All test values indicated herein are base
6、d on material with moisture content of 0.2% maximum (IS0 960, Method A; ASTM D789). Immediately after molding, specimens shall be sealed in moisture-proof containers and stored 23 + 2C for at least 24 h. All tests shall be performed on unannealed speci- mens immediately after their removal from the
7、containers in a controlled atmosphere of 23 f 2C and 50 + 5% RH unless otherwise specified. 4.3 A shear modulus plotted curve, as defined in SAE 51639, shall be provided with each GMP certification package. The temperature range 5C intervals is -50 to +21OC. 5 GENERAL INFORMATION. This standard was
