ASTM D5288
1. Scope
1.1 This test method was developed using copper electrodes to evaluate the low-voltage (up to 600 V) tracking resistance of materials in the presence of aqueous contaminants.
Note 1At this time, only industrial laminates have been examined using this method which was developed at the National Manufacturers Electrical Association (NEMA) laboratory located at the University of Cincinnati. It was found that a closer end point (less scatter) was obtained than with platinum electrodes, and materials tested tended to be ranked by resin system.
1.1.1 Other electrode materials may be considered for use with this test method depending upon the application of the insulating material.
1.2 This test method is similar to Test Method D 3638, which determines the comparative tracking index of materials using platinum electrodes to produce the tracking on the specimen surface.
1.3 The values stated in metric (SI) units are the standard. The inch-pound equivalents of the metric units are approximate.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
