Flammability Test Apparatus , Tracking Index Tester
Tracking Index Tester For Evaluating Leakage Resistance
Product introduction
This Tracking Index Apparatus is strictly designed and manufactured in accordance with IEC60112,IEC60335-1, IEC60598-1 and GB4207
Measure the relative resistance to traceability of the surface of the solid electrical insulating material when exposed to impurities containing water at a voltage of up to 600 V.
When the voltage is applied between the electrode means provided on the surface of the material and the electrolyte is dropped between the two electrodes at a predetermined time interval, it is possible to generate an electrical mark in this test case. The number of droplets necessary to cause material damage increases as the applied voltage decreases, and at less than a certain limit, no traceability occurs.
When the material in the highest test voltage is not electric marks, can have different degrees of corrosion, and corrosion depth can be measured. Some materials can burn during the test.
