Electrical leakage and scratch test (electrical trace index test) : the simulation test items stipulated in IEC60112, UL 746A, GB/T4207, GB4706.1, ASTM D 3638-92, etc. The test is in solid insulation material on the surface, in the specified size (2 mm x 5 mm) between the platinum electrode, applying a voltage and timing (30 s) high (35 mm) drop the conductive liquid droplet volume 0.1% (NH 4 CL), to evaluate solid insulation material surface under combined electric field and damp or pollution medium leakage resistance, compared to measure its electrical mark melt index (CT1) and electric mark the index (PT1). It is applicable to the research, production and quality inspection departments of lighting equipment, low-voltage electrical appliances, household electrical appliances, machine tools, electrical machinery, electric tools, electronic instruments, electrical instruments, information technology equipment, as well as the industry of insulation materials, engineering plastics, electrical connectors and accessories.
