Testing quality of electrically non-conducting protection on electrically conducting bases - involves applying AC test voltage and measuring current via test electrolyte on protective material

摘要

The method involves conductivity measurement with the conducting base (24) or object as one electrode and a neutral electrolyte carrier (23) on the protective material saturated with a test electrolyte matched to the partic. test requirements with a counter electrode. A potential-free a.c. test voltage is applied and a current measurement is performed after a number of time units or continuously or the current is recorded with a suitable recording device. The measurement values are displayed graphically to enable evaluation of the protective material (22). USE/ADVANTAGE - For testing protective material quality and characteristics wrt. chemical and physical factors with short testing times and limited equipment requirements.
