Tracking Index Test Apparatus
Tracking index test apparatus is designed according to IEC60112, UL746A, GB.T4207, GB4706.1 and TMD3628. It is applied to evaluate the leakage resistance (CTI and PTI) of the surface of insulating material. Tracking index test apparatus is mainly used in the industries of lighting appliance, low voltage appliance, household appliance, motor, electronic appliance, instrument and etc. It is a good tool for research department, production department and QC department.
Proof Tracking Index (PTI): the voltage value of the material subjected to 50 drops of electrolyte without electrical tracking, the unit is volt.
Comparative Tracking Index (CTI): The highest voltage value at which the surface of the material can withstand 50 drops of electrolyte without forming electrical tracking, the unit is volt.
Test solutions: The preparation ratio is 1:1000, that is 0.1g of NH4CI with 100g (100ml) of distilled water
