Item | Performance | |
Jolt test | No explosion, structural loose or damage after vibrating for 10min in the vibration machine | |
Initiating power | Use detonator No.4 to fire through 3mm thick lead plate, or No.8 to fire through 5mm thick lead plate, and the diameter of the hole is bigger than the out-diameter of the shell | |
Oil resistance | Immersed in 0＃diesel at 75℃ under 0.3Mpa for 24hrs, put out and initiate, no misfire or incomplete explosion | |
Tensile | Surface detonator | Pull with 19.6N static forces for 1min, shock tube can not be pulled out |
Inhole detonator | Pull with 78.4 N static forces for 1min, shock tube can not be pulled out | |
Water resistance | Surface detonator | Put under 1m deep water for 8hrs, performance doesn’t change |
Inhole detonator | Put under 30m deep water for 20hrs, performance doesn’t change | |
