This document specifies the method of test for the determination of the proof and comparative tracking indices of solid insulating materials on pieces taken from parts of equipment and on plaques of material using alternating voltage. The document provides a procedure for the determination of erosion when required. This test method evaluates the composition of the material as well as the surface of the material being evaluated. Both the composition and surface condition directly influence the results of the evaluation and are considered when using the results in material selection process. Test results are not directly suitable for the evaluation of safe creepage distances when designing electrical apparatus.
