Material approved to this specifi- cation shall meet the standard requirements in GM1002M. 3.1 COMPOUND CERTIFICATION. Material suppliers
4、 must certify molding compound properties to the specific GM Test Sampling Plan approved for their material. 3.2 COMPOUND PROPERTIES (NATURAL AND BLACK). See Table 1. 4 TEST PROCEDURES. 4.1 Test specimens shall be injection molded per IS0 294/l, as described in SAE 51639 unless otherwise specified.
5、4.2 All test values indicated herein are based 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 f 2C for at least 24 h. All tests shall be performed on unannealed speci- m
6、ens immediately after their removal from the containers in a controlled atmosphere of 23 k 2C and 50 f 5% RH unless otherwise specified. 4.3 COLORFASTNESS EVALUATION PROCEDURE. The color of each test specimen shall be measured per SAE J1545, CIELAB color space, 10” observer, illuminant D65, specular
7、 included, sphere geometry, before and after exposure. 4.4 A shear modulus plotted curve, as defined in SAB J1639, shall be provided with each GMP certification package. The temperature range, at 5C intervals, is -50 to +21OC. 5 GENERAL INFORMATION. This standard was origi- nated by the Plastics Com
