Audited Supplier Leakage marking test (electric marking index test) is to apply a voltage between platinum electrodes of specified size (2mm×5mm)on the surface of a solid insulating material and drop a specified volume of conductive liquid (0.1%NH 4CL) at a fixed height(35mm) at a fixed time (30s). It is used to evaluate the leakage resistance of solid insulating materials under the combined action of electric field and wet or polluted media, and to measure the relative electric staining index (CT1) and electric staining index (PT1).
CTI is to determine the insulation material compared to the electrical tracing index, which meets the DIN EN60112 standard. CTI simulates tracking the current between the insulation material through the dripping between the two electrodes. Commonly used insulation materials may be exposed to damp or dusty environments, which, if conducted, may cause heavy pressure or fire hazards.
This part complies with DIN EN 60112 / IEC 60112 / or VDE0303 Part 1. The test satisfies both the KA method (number of
drops/crawler channel depth) and the KA method (voltage up to the 50th drop). CTI and PTI values will be able to be determined.
The combination allows fine-tuning of test voltage, test current, switching time, drop size, and drop number.
Leakage marking tester is suitable for lighting equipment, low-voltage electrical appliances, household appliances, machine tools, electrical tools, electronic instruments, electrical instruments, information technology equipment research, production and quality inspection departments, but also suitable for insulation materials, engineering plastics, electrical connectors, accessories industry.
Industry knowledge
Compared with leakage marking, UL is divided into a total of 6 levels 0-5 corresponding to the test voltage range
0: The value is greater than or equal to 600V
1: less than 600V greater than or equal to 400V
2: less than 400V greater than 250V
3: The value is less than 250V and greater than 175V
4: less than 175V greater than or equal to 100V
5: The value is less than 100V and greater than 0V
