ISO/TR 6167:1984 PDF Download

ISO/TR 6167:1984 is a standard that provides methods of test to evaluate the contribution made by suspended ceilings to the protection of steel beams in floor and roof assemblies. The purpose of these tests is not to determine a separate fire-resistance classification for the ceiling alone. It is important to note that this standard is not applicable to ceilings used solely as horizontal partitions or as suspended false ceilings of the open cell or louvred types. The standard focuses specifically on the fire-resistance performance of suspended ceilings in relation to the protection of steel beams in floor and roof constructions.
