Vitreous and porcelain enamels. Determination of resistance to chemical corrosion - Determination of resistance to chemical corrosion by alkaline liquids using a hexagonal vessel or a tetragonal glass bottle1 Scope This document 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 hexagonal vessel in which six enamelled specimens or a tetragonal glass bottle in which four enamelled specimens are simultaneously tested. NOTE 1 The resistance to any alkaline liquid can be determined. However, the test method
