--- Part 7. rated voltage 6/10kV and below shielded rubber-sheathed cables;

--- Part 8. Rated voltage 0.3/0.5kV drill cables;

--- Part 9. Rated voltage 0.3/0.5kV light mine mobile rubber soft cable;

--- Part 10. Miner 's cap lamp cords. This section GB/T Part of 1,012,972. This Part replaces GB 12972.10-1991 "mining rubber-sheathed cables - Part 10. Miner cap lamp cords." This section compared with GB 12972.10-1991, the main changes are as follows:

--- Remove the cable jacket does not burn resistant properties of UM model (1991 edition Table 2);

--- Deleted Appendix A (1991 edition of Appendix A);

--- Cable burning test by the GB/T 18380.1 "burning wire and cable test method" to replace the original GB 12666.2 "single wire or cable Vertical burning test method "(1991 edition Table 3; Table 3 edition). This part is proposed by the China Electrical Equipment Industrial Association. This part of the National Standardization Technical Committee Wire and Cable (SAC/TC213) centralized. This part of the unit responsible for drafting. Shanghai Electric Cable Research Institute. Participated in the drafting of this section. Coal Research Institute Shanghai Branch, Shanghai Mine Cable Factory, Shanghai Nanyang Cable Co., Ltd., Baosheng Science and Technology Innovation Co., Ltd., Jiangsu on the cable Group Co., Ltd. The main drafters of this section. Zeng Ji Gang, Qu Bo, Wang Xi, Chen Tianrong, Tan Jinfeng, Li Xingjiang, Yuan Jie. This part of the standard replaces the previous editions are.

1 Scope

GB/T 12972.10-2008 is the Chinese national standard on flexible rubber-sheathed cables for mining purposes - part 10: miner's cap lamp cords, in the field of electrical engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 30 June 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 April 2009. Classification: ICS 29.060.20, CCS K13. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This section GB/T 12972 specifies the amount of miner's cap lamp wire product variety, technical requirements, test methods and inspection rules. This section applies to mineral insulated rubber sheathed cable with copper core rubber cap lamp. This section should be GB/T 12972.1-2008 common use.
