Tracking Resistance Tester for Insulation Material CTI and PTI Evaluation
Insulation materials may form conductive paths on the surface when exposed to moisture, contamination and electrical stress. Tracking resistance testing helps evaluate material performance for appliances, connectors, low-voltage electrical products and engineering plastics.
Important test elements
- Electrode material, spacing and pressure;
- Droplet height, interval and liquid volume;
- Test voltage, current limit and safety protection;
- Observation, ventilation and lighting;
- Test time and failure condition recording.
Laboratory use
Tracking resistance testers are often used together with glow wire testers, needle flame testers, horizontal and vertical burning testers and ball pressure test apparatus to build a complete material safety test laboratory.
LSKFT provides tracking resistance testers and related flammability test systems with customized fixtures and laboratory integration support.
