Vitreous and porcelain enamels. Low-voltage test for detecting and locating defects - Swab test for non-profiled surfaces has-tracked-changes Who is ISO 9015-1 -What is ISO 8289 1 about? ISO 8289 1 is the first part of a multi series international standard that covers the vitreous and porcelain enamels. 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,
