This document describes 2 test methods of high voltage testing:
Test A is used to detect and locate defects in vitreous and porcelain enamels;
Test B is used to detect and locate defects and weak spots in vitreous and porcelain enamels.
The tests are performed using DC, pulsed DC, or AC high voltage.
The tests are applicable to dry surfaces of enamel coatings. In the case of moist surfaces, care should be
taken to ensure that the locating of any defects is correctly performed.
Since test voltages depend on the coating thickness, the test method, especially with test A, may not be
suitable for test specimens for which the coating thickness varies to a large extent.
NOTE This document extends the range of application of the test given in ISO 2746, which is restricted to coating
thicknesses of minimum 660 um.
