标准范围

ISO 8573-2:2018规定了压缩空气中通常存在的液体油和油气溶胶取样和定量分析的试验方法。本文件不包括油蒸气的试验方法，因为它们在ISO 8573-5中有所涵盖。描述了两种不同的方法，方法A和方法B。方法B分为两部分，以明确区分获得分析油量的程序。方法A描述了一种使用内联凝聚过滤器的油收集技术，而方法B使用支架中的采样盘，从中用溶剂提取收集的油，并通过红外光谱法或带有火焰离子化检测的气相色谱法进行分析。ISO 8573-2:2018还包括使用指示剂型设备进行替代油气溶胶检测的说明，见附录E。

ISO 8573-2:2018 specifies test methods for the sampling and quantitative analysis of liquid oil and oil aerosols that can typically be present in compressed air. Test methods for oil vapour are excluded from this document as they are covered by ISO 8573？5.Two different methods are described, Method A and Method B. Method B is subdivided into two parts to clearly distinguish between procedures for obtaining the quantity of oil for analysis.Method A describes an oil collection technique using inline coalescing filters whereas Method B utilizes sampling discs in a holder from which the collected oil is extracted with a solvent and analysed by infrared spectrometry or gas chromatography with flame ionization detection.ISO 8573-2:2018 also includes descriptions of alternative oil aerosol detection by the use of indicator type devices, see Annex E.
