Vitreous and porcelain enamel finishes - Selection of test methods for vitreous and porcelain enamelled areas of articles (ISO 4528:2000); English version of DIN EN ISO 4528:2009-04
This International Standard is a guide to the selection of test methods for evaluating the performance of vitreous
and porcelain enamelled finishes in different applications. It references the test methods available for measuring
the properties of these finishes, and correlates these properties to requirements of specific enamelled articles.
It is limited for the most part to test methods that are described in ISO International Standards and does not provide
acceptance criteria or performance limits for the properties.
This International Standard applies to all enamelled articles irrespective of their basis metals.
