ULC 138

1 SCOPE

1.1 This is a fire test response Standard. This document describes the test method used to determine the contribution to fire growth provided by a non-loadbearing insulated building panel installed in a sprinklered or unsprinklered room configuration (see Appendix A).

1.2 The insulated building panels investigated by this test method are of the factory-assembled type and intended for use as exterior or interior walls, ceilings or roofs. This Standard presumes that these panels are not backed by other materials or constructions in typical installation practice.

Note: Where the panels are designed to be installed in a backed condition, the test specimen should be installed and evaluated in accordance with its intended use.

1.3 This test method measures the time to flashover under specified test conditions. Provisions are made to measure ignitability, smoke obscuration, rate of fire growth and rate of heat release of the test panels.

1.4 This test method is not intended to determine the fire resistance rating of insulated building panels. In addition, this test method does not investigate the toxic hazard posed by the products of combustion.

1.5 The exposure tests, as described herein, are not intended to be representative of all fire conditions. It is likely that conditions will vary with changes in the amount, nature and distribution of fire loading, ventilation, size and configuration of the assembly installed. These requirements provide a relative measure of the fire performance of comparable assemblies under these specified fire exposure conditions.

1.6 This Standard shall be used to measure and describe the response of materials, products or assemblies to heat and flame under controlled conditions.
