IEC 61482-1-1:20 19规定了测试方法程序，以确定用于工人服装的阻燃服装材料和服装或服装组件的电弧等级，如果存在电弧危险。 在受控实验室条件下的开弧用于确定材料、服装或服装组件的ELIM、ATPV或EBT值。 注1？如果用户希望，用户可以基于ELIM、ATPV和/或EBT值将电弧保护性能分类为电弧额定保护级别，所述ELIM、ATPV和/或EBT值最对应于可由用户的风险分析产生的不同危害和风险级别。 注2？本文件并不致力于将材料和服装的电弧防护性能划分为电弧防护等级。IEC 61482 1-中规定了确定这些电弧保护等级APC1和APC2的程序。2，其使用约束弧进行测试。 注3？本试验方法不旨在也不适合评估材料或服装是否阻燃，因为IEC 61482-2对此进行了规定。 除电弧热效应之外的其他效应，如噪音、光发射、压力上升、热油、电击、身体和精神冲击的后果或毒性影响不在本文件范围内。 有意使用电弧（如电弧焊、等离子炬）工作的防护服不在本文件范围内。 第二版取消并取代了2009年出版的第一版。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更: -添加入射能量极限(ELIM)作为另外的电弧额定值性能属性值；-用程序A适用于满足IEC 61482-2有限火焰蔓延要求的材料测试的指示取代范围内的炭长要求； -澄清斯托尔曲线的定义和含义； -根据测试样本的预期高入射能量暴露，修改监测传感器相对于电弧的定位规范； -监控传感器结构规格的修改； -黑色涂料的规格； -从人体模型的胸部消除热量计； -关于可能将人体模型定位在不同于电弧中心的高度和可能的转动以便充分暴露会影响性能的服装的所有部分的规范；-更明确地描述数据采集系统的要求； -样品的预处理； -修改设备和通过裸露射击进行电弧暴露验证的要求； -测试程序A和B的更明确描述，特别是涉及“测试顺序”、“测试参数”和“测试标准”的子条款； -增加确定服装和/或服装组件的电弧额定值。 关键词:防护服、热危害、开路电弧、电弧等级

IEC 61482-1-1:2019 specifies test method procedures to determine the arc rating of flame resistant clothing materials and garments or assemblies of garments intended for use in clothing for workers if there is an electric arc hazard.
An open arc under controlled laboratory conditions is used to determine the values of ELIM, ATPV or EBT of materials, garments or assemblies of garments.
NOTE 1？The user can, if he desires, classify the arc protective performance into arc rating protection levels based on ELIM, ATPV and/or EBT values which correspond best to the different hazard and risks levels that can result from the user’s risk analysis.
NOTE 2？This document is not dedicated to classifying the arc protective performance of the material and clothing into arc protection classes. Procedures determining these arc protection classes APC1 and APC2 are specified in IEC 61482 1-2, which uses a constrained arc for testing.
NOTE 3？This test method is not intended and not appropriate to evaluate whether materials or garments are flame resistant or not, as this is covered in IEC 61482-2.
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 document.
Protective clothing for work intentionally using an electric arc, e.g. arc welding, plasma torch, is not covered by this document.
This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
- addition of the Incident energy limit (ELIM) as a further arc rating performance property value;
- replacement of char length requirement in the scope by indication that Procedure A is applicable for testing of materials meeting the limited flame spread requirements of IEC 61482-2;
- clarification of the definition and the meaning of the Stoll curve;
- modification of specification of positioning of monitor sensors with respect to the electric arc as function of intended high incident energy exposure of test specimens;
- modification of specifications of monitor sensor construction;
- specification of black paint;
- elimination of calorimeters from the chest of the mannequin;
- specification for possible positioning of mannequin(s) at a height different from the centre of the electric arc and possible turning in order to adequately expose all parts of the garment or clothing which would affect performance;
- more explicit description of requirements for data acquisition system;
- preconditioning of the samples;
- modification of requirements for apparatus and arc exposure verification by bare shots;
- more explicit description of test procedures A and B, in particular the subclauses dealing with “sequence of test”, “test parameter” and “test criteria”;
- addition of determination of arc rating values of garments and/or garmet assemblies.
