ISO 8573-1:2010规定了与颗粒、水和油有关的压缩空气纯度等级，与规定或测量空气的压缩空气系统中的位置无关。 ISO 8573-1:2010提供了压缩空气系统中污染物的一般信息，以及ISO 8573其他部分的链接，用于测量压缩空气纯度或压缩空气纯度要求的规范。 除了上述颗粒、水和油的污染物外，ISO 8573-1:2010还确定了气体和微生物污染物。 附录A中给出了ISO 8573-1:2010应用指南。

ISO 8573-1:2010 specifies purity classes of compressed air with respect to particles, water and oil independent of the location in the compressed air system at which the air is specified or measured. ISO 8573-1:2010 provides general information about contaminants in compressed-air systems as well as links to the other parts of ISO 8573, either for the measurement of compressed air purity or the specification of compressed-air purity requirements. In addition to the above-mentioned contaminants of particles, water and oil, ISO 8573-1:2010 also identifies gaseous and microbiological contaminants. Guidance is given in Annex A on the application of ISO 8573-1:2010.
