This European Standard specifies requirements on thermal shock resistance as well as heating and cooling procedures of standardised glass-lined apparatus, components, accessories, and glass-lined pipes primarily used for process equipment in chemical plants.
It specifies the limits of thermal shock resistance using diagrams (see Figure 1 and Figure 2). For glass-lined steel, a difference is made between a thermal shock on the glass-lined side (by charging an apparatus) versus a thermal shock on the steel side (by heating and cooling an apparatus).
This European Standard applies to operating temperatures from - 25 °C to + 230 °C.
This European Standard is only applicable to enamelled unalloyed and low-alloy carbon steels.
