Fire-resistance tests — Guidance on the application and extension of results from tests conducted on fire containment assemblies and products — Part 2: Non-loadbearing elements

ISO/TR 12470-2:2017 explains a methodology to determine the applicability of the results of fire resistance tests to actual applications.

ISO/TR 12470-2:2017 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;

- linear gap sealing;

- service penetration sealing.

Fire resistance testing furnaces have fairly restricted size limitations and as a consequence, there is little confidence that the result obtained on an element of construction tested in accordance with the standard methods will behave in a similar manner when installe
