ASTM C536-83(2018)

This test method is designed to detect existing discontinuities in the glass coating of glassed steel equipment while maintaining a voltage low enough as to be unlikely to cause breakdown of the coating. The test is adaptable for manufacturing inspection in the processing of equipment and for field use to find existing defects which can be ?plugged? or repaired before serious damage is done to the equipment. As a means of positive detection, it is applicable to process studies, quality control, or specification.
