Safety frequency

No explosion charging with 10A current between 0～2KHz,    300KHz～∝ for 1min

Safety current

Under rated work    frequency, no explosion charging with 0.4A    effective current for 5min

Series firing current

20 pieces of    detonator connected into series circuit with 3.5A constant current, all explode

Static Sensitivity

2000pF,  15KV, magnetic ring to shell static    discharge, no explosion

Water Resistance

Put under 20m deep water for 20hrs, initiation    performance does not change

Jolt test

No explosion, structural damage, shortcut or disconnection    after vibrating for 10 minutes in the vibration machine

Initiating  Powder

Have a lead plate    test(5mm), after    initiation, the blowed diameter should not be smaller than the detonator OD
