Popis
BS EN ISO 28706-4:2016
This standard BS EN ISO 28706-4:2016 Vitreous and porcelain enamels. Determination of resistance to chemical corrosion is classified in these ICS categories:
- 25.220.50 Enamels
This part of ISO 28706 describes a test method for the determination of the resistance of vitreous and porcelain enamelled articles to attack by alkaline liquids at temperatures between 25 °C and 95 °C. The apparatus used is a cylindrical vessel in which only one enamelled specimen is tested.
NOTE 1
The test method was initially set up for determination of the resistance of vitreous and porcelain enamels to a hot sodium hydroxide solution. Within the scope of this part of ISO 28706 , the resistance of other alkaline liquids can be tested.
NOTE 2
This part of ISO 28706 , which uses a cylindrical vessel, is generally used for tests carried out on vitreous and porcelain enamel coatings for the chemical industry.
