Application Summary AI generated

This standard specifies the test method for evaluating the tracking resistance of insulating materials used in electric cables and wires. It is applied in quality control and type testing for cable insulation, particularly in environments where surface contamination and moisture can lead to electrical tracking and failure. The test is critical for cables used in power distribution, industrial equipment, and outdoor installations to ensure long-term reliability under wet or polluted conditions.
