1   Scope This document explains a methodology to determine the applicability of the results of fire resistance tests to actual applications. It is applicable to those non-loadbearing elements for which there is an ISO standard test procedure based upon the ISO 834 series for determining the fire resistance of a representative sample of the construction proposed for use in a specific building or just for general use. These elements are:

— fire resisting door assemblies (excluding lift landing doorsets):

— timber;

— steel;

— fire resisting vertical glazing – metal framed:

NOTE The rheology of glass is such that gravity has a disproportional influence on fire glass when it is heated to high temperatures and as a consequence, it is not possible to provide generic guidance on the extended application of horizontal glazed elements.

— timber framed;
