This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces TB/T 3138-2006 "Technical specification of flame retardant materials for railway locomotive and vehicle". Compared with TB/T 3138-2006, the main technical changes of this standard are as follows:
- MODIFY the division principle of structural material products used inside vehicles (see 3.2; 3.1 of the 2006 edition);
- ADD the sampling requirements for finished products of flame-retardant materials for railway locomotive and vehicle (see 3.1);
- ADD the flame retardant requirements of polymer materials (see 3.3.2); - ADD the flame retardant requirements of general rubber materials (see 3.6) - DELETE the physical and mechanical performance requirements of
materials (see Table 1 ~ Table 16 of the 2006 edition);
- MODIFY the number of samples and judgment conditions in Appendix A
(see Appendix A; Appendix A of the 2006 edition).
This standard was proposed by and shall be under the jurisdiction of the Institute of Standards and Metrology of China Academy of Railway Sciences Group Co., Ltd.
Drafting organizations of this standard: Institute of Metals and Chemistry of China Academy of Railway Sciences Group Co., Ltd., CRRC Qingdao Sifang
Rolling Stock Research Institute Co., Ltd., Standard Metrology Institute of China Railway Science Research Institute Group Co., Ltd., CRRC Tangshan Rolling Stock Co., Ltd. CRRC Nanjing Puzhen Vehicle Co., Ltd.
