EN-ISO 8289-1 specifies two low voltage tests for detecting and locating defects that extend to the basis metal in vitreous and porcelain enamel coatings.Method A (electrical) is applicable to the rapid detection and determination of the general location of defects. Method B (optical), based on colour effects, is applicable to the more precise detection of defects and their exact locations. Both methods are commonly applied to flat surfaces. For more intricate shapes, such as undulated and/or co...view more

This document describes a test method for the determination of the resistance of vitreous and porcelain
enamelled articles to attack by alkaline liquids at temperatures between 25 °C and 95 °C. The apparatus
used is a hexagonal vessel in which six enamelled specimens or a tetragonal glass bottle in which four
enamelled specimens are simultaneously tested.
NOTE 1 The resistance to any alkaline liquid can be determined. However, the test method was originally used
for the determination of the...
