ISO 4528

ISO 4528:2015 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 the requirements of specific enamelled articles. It is limited for the most part to test methods that are described in International Standards or European Standards and does not provide acceptance criteria or performance limits for the properties. ISO 4528:2015 applies to all enamelled articles irrespective of their basis metals.
