This International Standard specifies a method of test for deter-mining the resistance of flat surfaces of vitreous and porcelain enamels to boiling water and/or water vapour.
NOTE — If temperatures below the boiling point of water are used or if other than distilled water is used, this should be stated in the test report.
The method allows determination of the resistance of enamels to the liquid and vapour phases of the corrosive medium.
