What is ISO 13805 - Adhesion of vitreous and porcelain enamels on aluminium about?
ISO 13805 is an International Standard that discusses vitreous and porcelain enamels for aluminium. The main objective of ISO 13805 is to provide best industry practices to determine the adhesion behaviour of enamels on aluminium such that service life of the end-product is enhanced.
ISO 13805 specifies a test method for the accelerated determination of the resistance of porcelain enamel coatings on aluminium and aluminium alloys to spalling as a result of exposure to moisture or weathering.
Because of spalling is caused by the lack of adhesion between the coating and the base metal, the spall test is a test of adhesion. The greater the extent of spalling in this test, the greater the likelihood that the article will spall in service.
Who is ISO 13805 - Adhesion of vitreous and porcelain enamels on aluminium for?
ISO 13805 on adhesion of vitreous and porcelain enamel coatings on aluminium is useful for:
- Vitreous and porcelain enamel coating manufacturers
- Quality control and testing personnel
- Product design engineers
- Chemical engineers
- Automotive and aerospace industry
Why should you use ISO 13805 - Adhesion of vitreous and porcelain enamels on aluminium?
Poor adhesion causes spalling of porcelain enamelled aluminium, a defect defined by the separation of the porcelain enamel from the aluminium base material. The spall test is used to control the quality of the enamelling process, which includes the enamel formulation, preparation of the base metal prior to enamelling, application and burning techniques, and the aluminium alloy used for enamelling.
ISO 13805 provides guidance on the test procedure for evaluating the adhesive behaviour of vitreous and porcelain enamel coatings on aluminium and aluminium alloys. As a result, you can demonstrate the extent to which spalling can be prevented.
Compliance with the best-industry requirements specified in ISO 13805 can be beneficial for quality control purposes that can help you reduce negative environmental effects such as moisture or weathering. Consequently, you can improve the quality and service-life of aluminium and aluminium alloy components and products.
