Resistance

Galvanized steel core leg wire ≤6.3Ω, Range ≤2.0Ω

Safety current

Charging with 0.2A    constant direct current for 5min, no explosion.

Minimum firing current

≤0.45A

Firing impulse

2.0～7.9A2·ms

Series firing current

Connect 20 pieces of electric detonators    into series and charge with 1.2A    constant direct current, all detonators explode.

Initiating Power

Have a 5mm    lead plate test, and the hole diameter will not be smaller than the detonator    outer diameter.

Tensile

Charged with 19.6N static tension for 1min, no damage and removal to    the sealing and leg wire.

Anti-jolt property

No explosion, structure damage,    short circuit, open circuit and unstable performance after vibrating for    10mins.

Anti static

Leg wire to shell discharge with 8kV voltage, 2000pF capcitance and    0Ω series resistor, no firing.

Combustible gas safety degree

When initiating a permissible electric    detonator in the combustible gas of 9% thickness, the combustible gas should    not be initiated.
