Product Description
Standard Test Method for Comparative Tracking Index of Electrical Insulating Materials
PolyK has in-house test system to perform ASTM D3638 test in State College, PA, USA, with platinum electrode.
Relevant Test standards:
IEC 60664-1:2020 (Creepage Distances to Avoid Failure Due to Tracking)
UL 840, Table 9.1 (Minimum Acceptable Creepage Distances)
Our typical lead time is two-weeks.
Scope provided by ASTM:
"1.1 This test 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.
1.2 The values stated in metric (SI) units are to be regarded as standard. The inch-pound equivalents of the metric units are approximate.
1.3 This test method is technically equivalent to the version of IEC Publication 112 cited in 2.2. However, the 2007 version of IEC 60112 Fourth Edition yields numerical CTI values that are very likely to differ significantly from this test method."
