Description / Abstract:
This pan 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.
