| Explosion Shock Wave Resistance |
When detonating one standard electronic detonator underwater at a depth of one meter, it generates a shock wave. Ten adjacent detonators, evenly spaced 50 mm apart, should still function normally after exposure to this shock wave. |
| Anti-Static Performance |
The detonator does not explode when its leg wires are discharged at 25 kilovolts using a 500 picofarad capacitor and a 5,000 ohm series resistor. |
| Surge Current Resistance |
The system is equipped with a four-level protection circuit to prevent damage to the electronic ignition module from high-frequency, high-voltage transient currents, and low-frequency, low-voltage large currents. |
| Anti-Knock Property |
The detonator is subjected to a jolt tester with a cam speed of (60±1) r/min and a drop height of (150±2) mm for 15 minutes. During the test, the detonator could not explode, loosen, or suffer damage. After the test, the detonator could function normally. |
| Leg Wire Tensile Strength |
Under 40 kg (392N) static tension, the wire core and insulation layer should not break, damage, or short circuit. |
| Leg Wire Tensile Strength |
With a 2,700 g weight vertically applied to the insulation layer, and sandpaper in between, the insulation layer could not short-circuit after abrasion distance ≥300 mm. |
| Water Resistance |
The detonator could function normally after being submerged at 0.3 MPa water pressure for 72 hours. |
| Leg Wire Bending Resistance |
The leg wires could maintain normal conductivity without breaking or cracking after being bent 10 times in an environment ranging from -40°C (-40°F) to 85°C (185°F). |
| High and Low Temperature Resistance |
All performance metrics meet the standards, and the detonator functions normally in operating environments ranging from -40°C (-40°F) to 85°C (185°F). |
