| Abstract: |
| The work aims to study the detection rate of bottom events associated with initiating explosive devices in the fault of duds through the fire test of samples according to the reliability evaluation methods of GJB 376A-2019 and GJB 8185-2015, and propose more reasonable and scientific application methods and improvement suggestions. The Monte Carlo simulation method was used to study the detection efficiency of the reliability evaluation method specified in the two standards when the standard deviation estimation of the lifting method was unbiased. The method specified in GJB 376A-2019 was much more efficient for the detection of duds than the method specified in GJB 8185-2015. GJB 376A-2019 is more convenient for engineering applications. GJB 8185-2015 has limitations in the detection efficiency of duds. It is recommended to add restrictions on the non-igniting samples in the lifting test procedure carried out in the standard. |
