This standard specifies the measurement methods for the resistance and relative tracking index of solid insulation materials, which are applicable to equipment components and disc materials using alternating voltage. This standard specifies the measurement of erosion as required. Note 1:; The resistance to electric trace index serves as an acceptable judgment standard and method for quality control of materials and manufacturing parts. Compared to the electrical tracking index, it is mainly used for comparing the basic characteristics and performance of materials. The test results cannot be directly used to estimate the safe creepage distance during the design of electrical equipment. Note 2:; Through this experiment, it is possible to identify whether the raw materials used for electrical equipment working in humid environments have poor, average, or excellent resistance to electric tracing. To evaluate the performance of materials used outdoors, more rigorous long-term tests are required, using higher voltages and a large number of samples (see IEC 60587 inclined plate test). Other test methods such as the inclined plate method can arrange the materials in different order from the titration test provided in this standard
