ISO 28706-4 describes a test method for the determination of the resistance of vitreous and porcelain-enameled 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 enameled specimen is tested.
ISO 28706-4 specifies resistance to chemical corrosion by alkaline liquids using a cylindrical vessel.
NOTE 1: The test method was initially set up for the 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.
ISO 28706-4 on Vitreous and porcelain enamels - Determination of resistance to chemical corrosion is useful for:
ISO 28706-4 assists you with 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.
ISO 28706-4 provides the test method in which chemical corrosion is reacted by alkaline liquids using a cylindrical vessel.
