本国际标准规定了空气质量测量程序领域的: 根据静态条件下方法所有重要性能特征的实际值或声称值估算测量不确定度；评估这些性能特性的规定值是否符合规定被测量值的要求质量；基于实验室性能和验证性现场试验评估测量方法的适用性；制定仪器动态性能的要求。 本国际标准适用于输出为规定时间平均值的测量程序。

This International Standard specifies, for the field of air quality measurement procedures, the: estimation of measurement uncertainty from actual or claimed values of all important performance characteristics of a method under stationary conditions; assessment of whether or not specified values for these performance characteristics comply with the required quality of a measured value at a stated measurand value; evaluation of the applicability of the measurement method based on laboratory performance and confirmatory field test; establishment of requirements on dynamic behaviour of instruments. This International Standard is applicable to measurement procedures whose output is a defined time average.
