标准摘要
[中文适用范围]： 本文件规定了对从事焊接和相关工艺的人员（操作员）呼吸区空气悬浮颗粒进行采样的程序。它还提供了相关标准的详细信息，这些标准规定了工作场所空气测量的必要特性、性能要求和测试方法，并补充了 EN 689 中提供的有关评估策略和测量策略的指导。本文件还规定了对个人暴露于焊接和相关工艺（焊接烟雾）产生的空气悬浮颗粒以及焊接相关操作产生的其他空气悬浮颗粒进行重量测量的程序。此外，它还提供了其他标准中规定的适当化学分析方法的参考，以确定个人暴露于焊接烟雾和焊接相关操作产生的其他空气悬浮颗粒中的特定化学剂。 [外文原描述]： This document specifies a procedure for sampling airborne particles in the breathing zone of a person who performs welding and allied processes (the operator). It also provides details of relevant standards that specify required characteristics, performance requirements and test methods for workplace air measurement, and augments guidance provided in EN 689 on assessment strategy and measurement strategy. This document also specifies a procedure for making gravimetric measurements of personal exposure to airborne particles generated by welding and allied processes (welding fumes) and other airborne particles generated by welding-related operations. Additionally, it provides references to suitable methods of chemical analysis specified in other standards to determine personal exposure to specific chemical agents present in welding fumes and other airborne particles generated by welding-related operations.
