ULC CAN/ULC-S142:2016-R2021 STANDARD METHOD OF FIRE TEST FOR HEAT AND VISIBLE SMOKE RELEASE FOR DISCRETE PRODUCTS

1 SCOPE
1.1 This is a fire test method for determining the fire performance and smoke characteristics of discrete
products (including but not limited to electrical and plumbing equipment). These products are subjected to
an open flame ignition source and evaluated using a product calorimeter to determine the rate of heat
release and the rate of smoke release of the burning product samples.
NOTE: Discrete products as used in this Standard refers to stand-alone, non-continuous product that are not installed in a continuous
manner that could be tested in the tunnel equipment referenced in the Standard Method of Test for Surface Burning Characteristics of
Building Materials and Assemblies, CAN/ULC-S102. Examples of these types of products are speakers, valves, etc.
1.2 This test method does not provide information on the performance of products in other fire or test
conditions. This test does not investigate the toxicity of the products of combustion.
1.3 This test does not cover the constructional, electrical, or other performance requirements of the
product.
