压缩空气.第7部分:活微生物杂质含量的试验方法

[中文适用范围]： ISO 8573 的这一部分规定了一种测试方法，用于区分活的、形成菌落的微生物有机体（例如酵母、细菌、内毒素）与压缩空气中可能存在的其他固体颗粒。 它是旨在协调空气污染测量的一系列标准之一，提供了一种采样、培养和确定微生物颗粒数量的方法。 该测试方法适用于根据 ISO 8573-1 确定纯度等级，并且在需要识别也是可行的菌落形成单位的固体颗粒时与 ISO 8573-4 结合使用。 [外文原描述]： ISO 8573-7:2003 specifies a test method for distinguishing viable, colony-forming, microbiological organisms (e.g. yeast, bacteria, endotoxins) from other solid particles which may be present in compressed air. One of a series of standards aimed at harmonizing air contamination measurements, it provides a means of sampling, incubating and determining the number of microbiological particles. The test method is suitable for determining purity classes in accordance with ISO 8573-1, and is intended to be used in conjunction with ISO 8573-4 when there is need to identify solid particles that are also viable, colony-forming units.
