scope:

This document specifies requirements for assessment of the mechanical strength of metal profiles incorporating a thermal barrier having mechanical performance depending on their intended use. It also specifies the tests to determine the characteristic values of mechanical properties of the thermal barrier profile and to assess the effect of different conditionings of the thermal barrier on the mechanical performance of the connection. Thermal barriers which do not give a contribution to the mechanical resistance of the profiles are excluded from this document. This document applies to thermal barrier profiles designed mainly for windows, doors, screens and curtain walls. It does not apply to thermal barriers made only of metal profiles connected with metal pins or screws.
