Glass in building - Determination of the thermal shock resistance of glass panes by calculation

Scope

This document gives a method of determining the thermal shock resistance of glass. It gives the general method of calculation of temperature distribution and thermally induced stresses by temperature differentials in the glass pane.
NOTE Temperature differentials relevant for thermal shock resistance are caused by heat radiation and lead to temperature differential in the glass area.
This document does not determine suitability for purpose. Resistance to thermal shock is only one part of the design process, which could also need to take into account the resistance to perpendicular or/and in-plane loading. Those can be determined according to EN 16612, CEN/TS 19100-1, CEN/TS 19100-2 and CEN/TS 19100-3.
Other relevant design aspects could be:
• environmental factors (e.g. sound insulation, thermal properties),
• safety characteristics (e.g. fire performance, mode of breakage in relation to human safety, security).
This document does not apply to wired or unwired channel shaped glass, glass blocks and glass pavers.
The temperature differentials between the external and the internal surface of the glass pane are out of the scope of this standard.
The thermal load is derived from meteorological data, interior temperatures of given building type, location, orientation etc. A guideline on national climatic data determination will be given in the Annex A.
