Vitreous and porcelain enamels — Determination of crack formation temperature in the thermal shock testing of enamels for the chemical industry ISO 13807:1999

Publication date:   Dec 9, 1999

Scope

This International Standard specifies a test method for the determination of the crack formation temperature of
enamels for the chemical industry by subjecting enamelled steel specimens to thermal shock using cold water.
The value of the crack formation temperature measured according to this test method is not valid for the finished
component (see annex A). It is a parameter of vitreous and porcelain enamels for comparing the relative quality of
different enamel formulations.
