Blasting Scale  
Tensile Strength of Lead wire 196N for TPU wrapped copper wire.
Insulation of Lead wire Put the lead wire into water, both ends leaking out of the water and apply 5000V voltage on them maintaining 10s, the foot wire were not broken.
Abrasion Resistance of Lead Wire The min.wear time of the insulating layer is no less than10s under load 12.2N.
Electrostatic Discharge Resistance
 
A)Imposing an 25 000v charged 500pf capacitor with 5000 Ω in series, making the output ends of the devices to touch the 2 lead feet of product or foot - shell to discharge, the electronic detonator is not exploded or failure.
B)Using an 10 000v charged 2 000pf capacitor, making the output ends of the devices to touch the 2 lead feet of product or foot - shell to discharge, the electronic detonator is not exploded or failure.
Radio Frequency Resistance Imposing 10W radio frequency energy on electronic detonator under foot - foot and foot - shell modes, the electronic detonator is not exploded.
Free Drop Test Free fall unpacked product to a concrete floor from 5m height, no fire happens and the product still maintain functionality.
Impact resistance 2kg drop hammer impact test: Put the detonator into impact apparatus, drop 2kg hammer from 0.9m height to impact the primary and base charge parts of the detonator, no fire happens.  
Heat Stability Placed at 110 and maintained for 48h, the electronic detonator is not exploded.
