These test methods cover the evaluation of the relative tracking and erosion resistance of insulating solids using the liquid-contaminant, inclined-plane test.
Formerly under the jurisdiction of Committee D09 on Electrical and Electronic Insulating Materials, this practice was withdrawn in January 2013 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
1.1 These test methods cover the evaluation of the relative tracking and erosion resistance of insulating solids using the liquid-contaminant, inclined-plane test. The following test methods also can be used to evaluate the tracking resistance of materials: D 2132 (contaminants: dust and fog) and D 3638 (contaminant: conductive liquid drops).
1.2 Two tracking and one erosion test procedure are described:
1.2.1 A "variable voltage method" to evaluate resistance to tracking.
1.2.2 A "time-to-track method" to evaluate resistance to tracking.
1.2.3 A method for quantitative determination of erosion ().
1.3 While a particular contaminant solution is specified, other concentrations of the same contaminant, or different contaminants may be used to simulate different environmental or service conditions.
1.4 The values stated in inch-pound units are to be regarded as the standard.
1.5 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. Specific precautionary statements are given in Section 8.
