Scope of testing requirements (see Table 1, Table 1 of the.2008 edition);
---Increase the index requirements and test methods for oxidation induction time at.200°C (see Table 1, 4.11);
--- Added environmental performance requirements and test methods (see 3.3, 4.18);
---The requirements for standard samples have been added (see Table 3);
---Modified the test method of water content (see 4.6,.2008 edition 4.6);
---Added requirements for sample preparation in bending performance test and load deformation temperature test (see 4.9, 4.16);
---Modified the melting point test method (see 4.10,.2008 edition 4.10);
---Modified the requirements of sample preparation in the cantilever beam impact test (see Table 3, 4.13,.2008 edition 4.12);
---Modified the inspection rules (see Chapter 5);
--- Modified marking, packaging, transportation and storage (see Chapter 6, Chapter 6 of the.2008 edition);
--- Deleted the technical requirements and test methods of MPP loose casing (see Appendix A of the.2008 edition);
---Added Appendix A (Test Method for Water Content of Secondary Coating Materials) (see Appendix A);
---Appendix B (test method for compatibility of secondary coating material and filling compound) has been added (see Appendix B).
