41、very possible combination of the properties exists or can be obtained.4.3.3 An example of this classification system for a 33 % glass-reinforced polyphthalamide material, usingASTM test methods(Table A) is as follows:PPA0121G33A56577PPA0121 = Semicrystalline, low-temperature molding grade polyphthal

Properties in Tables A and B supersede properties in Table PPAwhen reinforced or filled materials are specified.7. General Requirements7.1 The
48、material compositions shall be uniform and shall conform to the requirements specified herein.8. Detail Requirements8.1 Test specimens for the various materials shall conform to the requirements prescribed in Tables PPA and A or B, and thesuffix requirements as they apply.8.2 For the purpose of dete

Conformance or nonconformance with this specification is based on this comparison.9. Sampling9.1 Sampling shall be statistically adequate to satisfy the requirements of 13.4.
