BS EN IEC 60950 Flammability Testing Equipment / High Current Arcing Igintion Tester

BS EN IEC 60950 Flammability Testing Equipment , High Current Arcing Ignition Tester


Product information:


The high current arcing igintion tester is used to measure and assess the arc resistance performance of insulator under the prescribed voltage. It is applicable for arcing resistance test of electric and electronic products, household appliances and its materials.


The test machine is designed and manufactured according to the requirement of IEC 60950-1,BS EN 60950-1,BS 7002, UL746A,IEC60947.1, IEC730.1.


The working principle is to simulate the electric leakage on the insulator which may cause among different polar of live parts or between live parts and grounded (earthed) metal parts.


Technical parameters:


Working voltage220V/50Hz,1KVA
Arc strike current33A±5%A
Arc strike speed40 times/min.
Electrode separation velocity254±25㎜/S
Arc strike times0-9999 can be preset
Electrode material

Static electrode—copper,dia.Ф3.5,top bevel angle 30°

Moving electrode—stainless steel,dia.Ф3.0, top cone angle60°

Electrode included angleForm 45°with level,electrode head radius of curvature 0.1mm
Dropping liquid interval30±5S,adjustable
Dropping liquid height35±5mm
Dropping liquid delay0.2S(magnetic valve opening time)
Dropping liquid size45~50 drops/cm3
The heavy current arc ignition tester adopts dual electrodes. It has specific current (33A) and power factor (COSφ0.5), according to a certain arc strike speed (254mm/s) and repetition frequency (40 times/min), repeatedly arc strike to 200 times on the surface of specimen. The large current arc ignition performance (HAI) can be assessed according to whether the sample can be ignited. The smaller of the grade number, the more difficult for burning material.
