ISO 10439规定了轴流压缩机、单轴和整体齿轮工艺离心压缩机以及用于石油、石化和天然气行业中处理气体或工艺空气的特殊用途应用的膨胀压缩机的最低要求并给出了建议。ISO 10439-1:20 15规定了适用于所有此类机器的一般要求。 ISO 10439-1:20 15不适用于风扇（API 673涵盖了这些）或鼓风机，其压力上升低于大气压力34 kPa（5 psi）。它也不适用于API 672涵盖的成套整体齿轮离心设备和仪表空气压缩机。ISO 10439-1:20 15不涵盖超过300°C（570°F）的热气膨胀机。 ISO 10439-1:20 15包含与ISO 10439其他部分涵盖的所有设备相关的信息。它应与ISO 10439的以下部分结合使用，适用于所涵盖的特定设备: ISO 10439？2; ISO 10439？3 ISO 10439？4

ISO 10439 specifies minimum requirements and gives recommendations for axial compressors, single-shaft, and integrally geared process centrifugal compressors, and expander-compressors for special purpose applications that handle gas or process air in the petroleum, petrochemical, and natural gas industries. ISO 10439-1:2015 specifies general requirements applicable to all such machines. ISO 10439-1:2015 does not apply to fans (these are covered by API 673) or blowers that develop less than 34 kPa (5 psi) pressure rise above atmospheric pressure. It also does not apply to packaged, integrally geared centrifugal plant, and instrument air compressors, which are covered by API 672. Hot gas expanders over 300 °C (570 °F) are not covered by ISO 10439-1:2015. ISO 10439-1:2015 contains information pertinent to all equipment covered by the other parts of ISO 10439. It shall be used in conjunction with the following parts of ISO 10439, as applicable to the specific equipment covered:

• ISO 10439？2;
• ISO 10439？3
• ISO 10439？4
