这是一种火灾试验方法，用于确定离散产品（包括但不限于电气和管道设备）的防火性能和烟雾特性。将这些产品置于明火点火源下，并使用产品热量计进行评估，以确定燃烧产品样品的热释放速率和烟雾释放速率。注:本标准中使用的离散产品是指未以连续方式安装的独立非连续产品，可在建筑材料和组件表面燃烧特性标准试验方法CAN/ULC中引用的隧道设备中进行试验- S102。此类产品的示例包括扬声器、阀门等。本试验方法不提供有关产品在其他火灾或试验条件下性能的信息。本试验不调查燃烧产物的毒性。本试验不包括产品的结构、电气或其他性能要求。

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.
