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

  • Model:

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.

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.
