inactive
Buy Now
Organization: ASTM
Publication Date: 30 December 1977
Status: inactive
Page Count: 5
scope:

This method evaluates in a short period of time the low-voltage (up to 600 V) track resistance or comparative tracking index (CTI) of materials in the presence of aqueous contaminants.

NOTE 1 -The values stated in metric (SI) units are to be regarded as standard. The U.S. customary equivalents of the metric units may be approximate.
