Introduction:
Arc resistance, in accordance with ASTM-D495, is expressed as the number of seconds that a material resists the formation of a surface-conducting path when subjected to an intermittently occurring arc of high voltage, low current characteristics.
The results of testing the nominal 3 mm thickness are considered representative of the material's performance in any thickness.
