Roof-Deck assemblies employ specific combinations of adhesives, vapour barriers, insulating materials and roof coverings which may contribute to the spread of fire in the interior of buildings. This test method is intended to be used in assessing the fire spread of such assemblies utilizing metallic or non-metallic roof-deck materials when exposed to fire within a building.
This test method utilizes the 7.6 m tunnel test apparatus described in the Standard CAN/ULC-S102, Standard Method of Test for Surface Burning Characteristics of Building Materials and Assemblies. The limits of spread of flame on the underside of the assemblies subjected to this test method were established by a comparison of the results on roof-deck assemblies with large scale fire tests (30.5 m by 6.0 m building).
The assemblies used to establish these limits, were known by experience in actual installations either to have contributed extensively to the spread of fire or, conversely, were regarded as acceptable.
This test does not provide a fire resistance rating such as the rating which is attained in CAN/ULC-S101, Standard Methods of Fire Endurance Tests of Building Construction and Materials.
