ISO 8573-8:2004规定了测定压缩空气中固体颗粒质量浓度的试验方法，表示为具有最大粒径限制的固体颗粒质量。还规定了这些方法的局限性。该标准是旨在协调空气污染方法的一系列标准之一，它确定了采样技术，并给出了空气纯度参数固体颗粒质量浓度的评估、不确定度考虑和报告要求。试验方法适用于根据ISO 8573-1确定纯度等级。（基于颗粒计数的颗粒含量在ISO 8573-4中进行了说明。）

ISO 8573-8:2004 specifies test methods for determining the solid particle mass concentration in compressed air, expressed as the mass of solid particles with maximum particle size limits. The methods' limitations are also specified. One of a series of standards aimed at harmonizing air contamination methods, it identifies sampling techniques and also gives requirements for evaluation, uncertainty considerations and reporting for the air purity parameter solid particles by mass concentration. The test methods are suitable for determining the purity classes in accordance with ISO 8573-1. (Particle content based on counting particles is dealt with in ISO 8573-4.)
