标准摘要
[中文适用范围]： 本文件规定了测定工作场所大气中化学试剂浓度的程序的一般性能要求。 这些要求适用于测量程序的所有步骤，无论化学试剂的物理形式（气体、蒸气、空气颗粒）、采用单独采样和分析方法的测量程序以及直读装置。 由于实践中遇到的各种环境条件，本文件规定了在规定的实验室条件下进行测试时测量程序必须满足的要求。 [外文原描述]： ISO 20581:2016 specifies general performance requirements for procedures for the determination of the concentration of chemical agents in workplace atmospheres. These requirements apply to all steps of measuring procedures regardless of the physical form of the chemical agent (gas, vapour, airborne particles), measuring procedures with separate sampling and analytical methods, and direct-reading devices. ISO 20581:2016 specifies requirements that have to be fulfilled by measuring procedures when tested under prescribed laboratory conditions due to a wide range of environmental conditions encountered in practice.
