BS 476-20 Fire Resistance Test to Building Material-Standard

Fire Tests on Building materials and structures – Part 20. Method of test for determination of the fire resistance of elements of construction ( General principles)

BS 476-20 Fire Resistance Test to Building Material-Standard Brief

The objective of determining fire resistance, as described in the part and the associated parts of BS 476, is to assess the behaviour of a specimen of an element of building construction when subjected to defined heating and pressure conditions. The method provides a means of quantifying the ability of an element to withstand exposure to high temperatures, by setting criteria by which the loadbearing capacity, the fire containment ( integrity) and the thermal transmittance ( insulation) functions can be adjudged.

A representative sample of the elements is exposed to a specified regime of heating and the performance of the test sample is monitored on the basis of criteria described in the standard. Fire resistance of the test elements is expressed as the time for which the appropriate criteria have been satisfied. The times so obtained are a measure of the adequacy of the construction in a fire but have no direct relationship with the duration of a real fire.

BS 476-20 describes a procedure for a laboratory test for the determination of fire resistance of elements of construction.
