High voltage spark testers for coatings
Did you know?
WebHigh voltage holiday test is normally used to determine the existences of discontinuities in coating films. The high voltage, or porosity technique, can be used to test coatings up to 25mm (1") thick and is ideal for inspecting pipelines and other protective coatings. Coatings on concrete can also be tested using this method. WebThe objective of this International Standard is to achieve uniformity of practice for the detection of porosity in a dry film. The methods chosen entail the detection of porosity using one of two types of equipment, a low-voltage pinhole detector or a high-voltage spark tester.
WebThe Elcometer 270 Pinhole Tester is available in either dual or triple voltage models. The dual voltage model can be set to 9V, for testing thin coatings up to 300 microns (12 mils) … WebThe main technique used for porosity testing of protective coatings is the high voltage test where a probe with a voltage, measured in kilovolts (kV,) is applied to the coating and …
