GB/T 9978 Fire Test to Building Material –Standard Describe

The objective of determining fire resistance, as described in the part and the associated parts of GB/T 9978, 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.
