标准范围

IEC 61482-1-2:20 14规定了在存在电弧危险的情况下测试用于工人耐热和阻燃服装的材料和服装的程序。测试电路中的定向和约束电弧用于将材料和服装分为两个定义的电弧保护类别。本国际标准不专门用于测量电弧额定值（ATPV、ELIM或EBT）。IEC 61482-1-1中规定了确定这些电弧额定值的程序，使用开路电弧进行测试。本标准不涵盖电弧的热效应以外的其他效应，如噪声、光发射、压力升高、热油、电击、身心冲击或毒性影响等。故意使用电弧工作的防护服。g.电弧焊、等离子炬不在本标准范围内。第二版取消并取代了2007年出版的第一版。本版本为技术修订版，包括与上一版本相关的以下重大技术变更:-主要控制参数电弧能量和入射能量的新平均值基于由四个实验室测量的参数值组成的扩展统计数据库；-减少主要控制参数的有效性检查范围；-通过平均测试的两个传感器值(而不是考虑每个单个传感器值)来确定入射能量；-确定透射入射能量的热曲线和对热通量验收标准的修正；-澄清范围；-以及通过电弧能量和入射能量的量而不是短路电流来选择电弧保护等级(测试等级)。

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.
