|
Water resistance |
Under normal temperature, immerse the electronic detonator in water with a pressure of (0.3±0.002) MPa for 4hrs. After being taken out, initiation performance does not change |
|
Anti- temperature |
In 85℃ for 4 hrs, no explosion.After taking out, detonate normally. In -40℃ for 4 hrs, After taking out, detonate normally. |
|
Anti- temperature and impact resistance |
The electronic detonator in -40℃for 3hrs and then in 85℃for 3hrs ,the temperature conversion time is 20s-30s , and the electronic detonator should not explode after three cycles .After taking it out , at room temperature for 1h , and the electronic detonator can detonate normally. |
|
Tensile |
19 .6N , the wires and plugs connectors should not be damaged or moved visually , and the electronic detonator be able to detonate normally. |
|
Anti static |
Leg-wire to leg-wire , leg-wire to shell(25KV/500PF/500Ω ) , discharge no ignition Leg-wire to leg-wire , leg-wire to shell(8KV/2000PF/0Ω ) , discharge no ignition |
|
Anti-stray current |
100mA stray current is introduced into the bus, and the detonator and initiator communicate normally. Single detonator applied stray current of 250mA for 5min, without accidental detonation. |
|
Resistance to RF |
RF energy with a power of 10w into the electronic detonator , and the electronic detonator should not explode in two modes:leg-wire to leg-wire and leg-wire to shell . |
|
Anti-impact |
Under the condition that the weight is (2.0 ±0.002) kg and the height is (0.8±0.01) n, the electronic detonator should not explode when it hits the head fuse and the charging part of the primary explosive respectively. |
|
Flexibility |
Under 50N, 90 ° angle gravity, no fracture or damage to the shell |
|
Anti- drop |
No explosion under 5 m of free drop and led drop |
|
Jolt test |
150mn high, 60Hz frequency, 10min vibration, no explosion and structural damage of detonator. |
|
Network test |
Test and verify in two-way communication, make sure no problem , and blast successfully |
|
Network capacity |
Single blasting machine connects no more than 400pcs detonators; When over 6000pcs, use the synchronized blasting machine |
