CAN/ULC-61482的本部分规定了测试方法，以测量拟用于接触电弧热效应的工人的耐热和阻燃服装材料的电弧热性能值，以及使用这些材料的服装的功能。这些试验方法测量满足以下要求的材料的电弧热性能值:当按照ISO 15025，程序B（底部边缘点火）对外部材料进行试验时，从火焰中移除后小于100 mm的炭长度和小于2 s的余火，以及使用改进的ISO方法测量的炭长度。这些方法用于测量和描述材料、产品、组件或服装的特性，以响应受控实验室条件下露天电弧产生的对流和辐射能。 （IEC 61482-1-1-2009，等同标准）

This part of CAN/ULC-61482 specifies test methods to measure the arc thermal performance value of materials intended for use in heat- and flame-resistant clothing for workers exposed to the thermal effects of electric arcs and the function of garments using these materials. These test methods measure the arc thermal performance value of materials which meet the following requirements: less than 100 mm char length and less than 2 s afterflame after removal from flame, when tested in accordance with ISO 15025, procedure B (bottom-edge ignition) on the outer material, and the char length measured using a modified ISO method.These methods are used to measure and describe the properties of materials, products, assemblies or garments, in response to convective and radiant energy generated by an electric arc in open air under controlled laboratory conditions.
