High Voltage Arc Tracking Rate Tester (UL 746A)

High voltage arc tracking rate tester is denoted as the rate, in millimeters per
minute, that a tracking path can be produced on the surface of the material
under standardized test conditions.

A note is made if ignition on the material
takes place. The results of testing the nominal 3 millimeter thickness are
considered representative of the material's performance in any thickness.
