ISO 8573-6:20 03为测量压缩空气中的污染气体提供了一系列合适的测试方法。它规定了适用的气态污染物一氧化碳、二氧化碳、二氧化硫、一氧化氮、二氧化氮和C1至C5范围内的碳氢化合物的采样技术、测量和评估、不确定性考虑和报告（C6及以上参见ISO 8573-5）。给出的方法也适用于其他气体。

ISO 8573-6:2003 provides a selection of suitable test methods for the measurement of contamination gases in compressed air. It specifies sampling technique, measurement and evaluation, uncertainty considerations and reporting for the applicable gaseous contaminants carbon monoxide, carbon dioxide, sulphur dioxide, nitric oxide, nitrogen dioxide, and hydrocarbons in the range C₁ to C₅ (see ISO 8573-5 for C₆ and above). The methods given are also suitable for other gases.
