This International Standard describes a method of test for comparing the performance of insulating materials, when they are exposed intermittently to a liquid contaminant and then to an a.c. electric stress along their surface. It should be realized that the test was developed to compare the resistance to tracking and erosion of materials belonging to one specific family, so that comparisons between results in different families may not be fully valid.
