Description
The porosity test is performed with a low-energy high DC voltage.The test voltage can be from 0 to 15 kV. The test voltage is determined exclusively by the thickness of the layer to be tested. Therefore the film thickness should be measured before testing in order to prevent high voltage damage. A reference table which is part of the delivery content helps to determine the best test voltage which depends on the layer thicknesses.
The test procedure is performed by slowly pulling the brush with ca. 30 cm/s over the layer to be tested. A defect is indicated by sparkover and additionally by an audible and visual signal. The sensitivity is adjustable. For optimum test results different brushes are available like flat brushes and round brushes for internal and external testing on tubes.
