Vitreous and porcelain enamels. Low-voltage test for detecting and locating defects - Slurry test for profiled surfaces
What is ISO 8289-2 - Vitreous and porcelain enamels about?
The ISO 8289 series is an International Standard that covers vitreous and porcelain enamels. The main purpose of ISO 8289 is to provide low-voltage test methods for detecting and locating defects. ISO 8289-2 is the second part of the series that specifies a low-voltage test method for detecting and locating defects that occur in enamel coatings of corrugated and/or undulated profiles and that extend down to the metal base. The method is based on color effects (optical method) and is applicable to the precise detection of defects and their exact position. It can be used for non-flat, more profiled shapes such as corrugated or undulated surfaces. Note: The low-voltage test is a non-destructive test for detecting defects extending down to the metal base and is, therefore, completely different in comparison to the high-voltage ...
