Leakage Current Tracking Tester is designed to evaluate the tracking resistance of solid electrical insulating materials under humid conditions. By applying voltage across a specimen and dripping a conductive liquid, the tester simulates the electrical stress and evaluates the material's resistance to surface tracking. The equipment is widely used in electronics, plastics, electrical, and automotive industries for quality control and performance assessment of insulating materials and electrical components.

Standards

The tester complies with the following national, industry, and international standards:

GB/T 4207-2003: Determination of comparative and proof tracking indices of solid insulating materials under wet conditions

IEC 60112: Test methods for electric strength and tracking resistance of solid insulating materials

UL 746A: Plastic Materials – Short Term Property Evaluations

IEC 60216: Thermal aging tests for electrical insulating materials

ASTM D2344: Standard methods for insulation material aging tests

IEC 60529: Degrees of protection provided by enclosures for electrical equipment

GB/T 5169: Safety testing standards for electrical products
