This part of ISO 28721 specifies requirements for applies to quality 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 distinction is made between a thermal shock on the glass-lined side (produced by charging an apparatus) and a thermal shock on the steel side (produced by heating or cooking an apparatus) The part of ISO 28721 applies to operating temperatures from -25 °C to +230 °C It is only applicable to enamelled unalloyed and low-alloy carbon steels.
