Scope
This International Standard specifies a method of test for the determination of resistance to sulfuric acid, at room temperature, of vitreous and porcelain enamelled articles, and also specifies a method for classifying the results.
It is particularly intended for the testing of vitreous and porcelain enamelled articles that come into contact with products of combustion containing sulfuric acid.
It is not applicable to vitreous and porcelain enamels that come into contact with weak acids or hot strong acids or to vitreous and porcelain enamelled articles for use in the chemical industry.
NOTES
1 For testing the resistance to citric acid of vitreous and porcelain enamels at room temperature, see ISO 2722.
2 For testing the resistance to boiling citric acid, see ISO 2742.
3 For testing the resistance to condensing hydrochloric acid vapour of vitreous and porcelain enamelled surfaces of containers and equipment used in the chemical industry, see ISO 2743.
