Scope:

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.
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.
This test does not cover the constructional, electrical, or other performance requirements of the product.

Project need:

The revision in the Note clarifies existing practices and understanding that CAN/ULC-S142 methodology is for products that are stand-alone objects that cannot be manufactured into a single continuous material, often referred to as discrete products. Building Materials that are continuous and by its own structural quality or the manner in which it is applied, is capable of supporting itself in position or being supported in the test furnace to a thickness comparable to its intended use are traditionally tested in the tunnel to the CAN/ULC-S102.
