HG/T 3330-2012 "Determination of the breakdown strength of insulating paint films" specifies a method for determining the breakdown strength of insulating paint films. This standard applies to the application of AC voltage to the breakdown of the paint film by means of continuous uniform pressure boosting under certain conditions. The breakdown strength E is expressed in kilovolts per millimeter (kV/mm) as the ratio of the breakdown voltage to the thickness of the paint film. The standard cites several specifications, such as methods for sampling raw materials for Paints and varnish, specifications and test methods for analytical laboratory water, and temperature Humidity requirements for conditioning and testing of Coating specimens. The test process requires the use of accuracy +/- 2 ℃ oven, and breakdown strength test equipment including high voltage transformer, overcurrent relay, voltage adjustment device and voltmeter.
