This current must be measured under steady-state conditions that is neither a charging current nor a space-charge, build-up polarization current.<\/p>\n<p>1.2 This test method is intended for the determination of sensitivities less than 10 [omega][dot]cm in the temperature range from 25\u00b0C to the annealing point of the glass.<\/p>\n<p>1.3 This standard does not purport to address all of the safety problems, 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.
