标准摘要
[中文适用范围]： IEC 61482 的这一部分规定了测试用于工人耐热和阻燃服装的材料和服装是否存在电弧危险的程序。测试电路中的定向和约束电弧用于将材料和衣服分类为两个定义的电弧防护等级。本国际标准并非专门用于测量电弧额定值（ATPV1@ ELIM2 或 EBT3）。 IEC 61482-1-1@ 中规定了使用明弧进行测试来确定这些电弧额定值的程序。除电弧热效应外的其他效应，如噪声@光发射@压力上升@热油@电击@身体和精神冲击或有毒影响的后果不包括在本标准中。本标准不包括用于有意使用电弧@（例如电弧焊@等离子焊炬@）工作的防护服。 [外文原描述]： IEC 61482-1-2:2014 specifies procedures to test material and garments intended for use in heat and flame-resistant clothing for workers if there is an electric arc hazard. A directed and constrained electric arc in a test circuit is used to classify material and clothing in two defined arc protection classes. This International Standard is not dedicated toward measuring the arc rating values (ATPV, ELIM, or EBT). Procedures determining these arc rating values are prescribed in IEC 61482-1-1, using an open arc for testing. Other effects than the thermal effects of an electric arc like noise, light emissions, pressure rise, hot oil, electric shock, the consequences of physical and mental shock or toxic influences are not covered by this standard. Protective clothing for work intentionally using an electric arc, e.g. arc welding, plasma torch, is not covered by this standard. This second edition cancels and replaces the first edition, published in 2007. This edition constitutes a technical revision which includes the following significant technical changes with regard to the previous edition: - new mean values of main control parameters arc energy and incident energy based on an extended statistical database consisting of parameter values measured in four laboratories; - reduction of validity check ranges of main control parameters; - determination of the incident energy by averaging the two sensor values of a test (instead of considering each single sensor value); - determination of the heat curves of transmitted incident energy and an amendment to the heat flux acceptance criterion; - clarification of the scope; - and selection of the arc protection classes (test classes) by the amount of the arc energy and incident energy instead of the short-circuit current.
