GB/T 9786-2015Industrial detonating cord (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard replaces GB 9786-1999 "ordinary detonating cord" and GB/T 12439-1990 "source detonating cord." This standard GB 9786-1999 based, integrated GB/T 12439-1990 "source detonating cord," the part with the original standards Ratio, the main technical changes as follows.

--- Increasing the definition of industrial detonating cord (see 3.1);

--- Modify the common source and detonating cord detonating cord classification of industrial detonating cord are classified (see 4.1, GB 9786-1999 of And 3.1 GB/T Cap 312439-1990's);

--- Increased industrial detonating cord code (see 4.2);

--- Modify the common source and detonating cord detonating Soso dry appearance requirements, increasing industrial detonating cord surface color requirements, warning signs Requires identification and registration requirements (see 5.1.1 ~ 5.1.3, GB 9786-1999 and 4.1 GB/T 12439-1990 4.2);

--- Remove the common source and detonating cord detonating cord outer diameter size requirements (see 4.2 GB 9786-1999 and GB 12439-1990 4.2);

--- Modify the common source and detonating cord detonating cord loading dose requirements, according to charge different amounts of industrial detonating cord were given doses public Deviation Requirements (see 5.3, GB 4.3 and GB/T 12439-1990 4.4 in 9786-1999);

--- Modify the common source and detonating cord detonating cord performance indicators (see 5.4, GB 9786-1999 and 4.4 GB/T 12439-1990 4.5);

--- Delete the content of ordinary detonating cord "initiating properties" and "flame flu" indicator (see 4.4.4 and GB 9786-1999 4.4.7);

--- Modify the common source and detonating cord detonating cord connecting the booster performance test methods (see Appendix A, GB 9786-1999 Figure 1 and GB/T 12439-1990 Fig. 2)

--- Remove the common source and detonating cord detonating cord booster performance and water resistance test method to use the content of fire detonator, Remove the water resistance test connection diagram (see Figure 2 5.5,5.6.1 and GB/T 12439-1990 and GB 9786-1999 in The 5.5, 5.6 and 3);

--- Increased industrial detonating cord and line detection methods lack the shortest cable length (see 6.1 and 6.2);

--- Modify the common inspection rules detonating cord and source of detonating cord, detonating cord of industrial inspection is divided into type inspection and factory inspection And provides a unified sampling program (see 7.1 ~ 7.4.4, GB 9786-1999 6.1 to 6.6 and GB/T 12439-1990 The 6.1 - 6.13);

--- Modify the source detonating cord shelf life (see 9.3, GB/T 12439-1990 in 7.4.2).
