带电作业.防电弧热危害的防护服.第2部分:要求

[中文适用范围]： 本部分 IEC 61482 适用于存在电弧危险暴露风险的工作中使用的防护服。本文件规定了针对电弧热危害的电气工人防护服装材料和服装的要求和测试方法。本文件不涉及触电危险，应与涵盖此类危险的标准结合使用。除电弧热效应外的其他效应（如噪音、光辐射、压力上升、热油、触电、身心冲击后果或有毒影响）不在本文件范围内。本文件不包括对眼睛、面部、头部、手部和脚部的电弧危险保护。故意使用电弧的工作（如电弧焊、等离子炬）的防护服不在本文件范围内。 [外文原描述]： IEC 61482-2:2018 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61482-2:2018 is applicable to protective clothing used in work where there is the risk of exposure to an electric arc hazard. This document specifies requirements and test methods applicable to materials and garments for protective clothing for electrical workers against the thermal hazards of an electric arc. Electric shock hazard is not covered by this document, which is applicable in combination with standards covering such hazards. 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. Protection of eyes, face, head, hands and feet against electric arc hazard is not covered by this document. Requirements and tests to cover electric arc hazards to these parts of the body are under development. 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: new definition for ELIM, ATPV and EBT as used in accordance with IEC 61482-1-1:–; new requirements for the thermal stability of the intermediate layers; additional material requirement for volume resistance; new test procedure for the thermal resistance of sewing threads and a new symbol for marking.
