ISO 2744:1998 PDF

Scope: This International Standard specifies a method of test for determining the resistance of flat surfaces of vitreous and porcelain enamels to pure boiling water and/or water vapour (see note 1). This International Standard is also suitable for determining the resistance of vitreous and porcelain enamels to any other water for example to drinking water and river water. The method is also applicable to determination of the resistance of enamels to the liquid and vapour phases of the corrosive medium. NOTES 1 If temperatures below the boiling point of water are used this should be stated in the test report. 2 The resistance of vitreous and porcelain enamel to water generally depends on the pH value and of the substances in the water. In addition, the test results obtained in the liquid phase are influenced by the corrosion products of the vitreous and porcelain enamel and also of the borosilicate glass of the testing apparatus. Therefore, the test results obtained for different exposure times can differ (see also note in 8.1).
