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, is applicable to the more precise detection of defects and their exact locations. Both methods are commonly applied to flat surfaces.
Note: Selection of the correct test method is critical to distinguish the areas of increased conductivity detected by method B from actual pores that extend to the basis metal, which can be detected by both methods.
Note: The low voltage test is a non-destructive method of detecting defects and, therefore, is completely different from the high voltage test specified in ISO 2746. The results of the high and low voltage tests are not comparable and will differ.
Who is ISO 8289-1 for?
ISO 8289-1 on vitreous and porcelain enamels is applicable to:
- Manufacturers Industrial porcelain enamel
- Manufacturers of laboratory equipment
- Manufacturers of kitchenware and appliances
- Manufacturers of bathroom fixtures
- Jewellery Manufacturers
Why should you use ISO 8289-1?
Resolving enamel defects is important during an industrial porcelain manufacturing process.
ISO 8289-1 helps in identifying defects in vitreous and porcelain enamel coatings. ISO 8289-1 provides you with the guidelines of voltage tests detecting and locating defects of vitreous and porcelain enamel coatings which helps comprehensive quality and durability improvement.
Precise detection and localization of faults in vitreous and porcelain enamel coatings are important for boosting coating efficiency in a variety of applications. ISO 8289-1 recommends low voltage testing because it is convenient and cost-effective, hence lowering manufacturing costs.
What’s changed since the last update?
BS EN ISO 8289-1:2020 supersedes BS EN ISO 8289:2001, which is withdrawn. BS EN ISO 8289-1:2020 has been technically revised.
