ISO 10439规定了最低要求，并为轴压式压缩机，单轴和整体齿轮式离心式压缩机以及用于处理石油，石油化工和天然气工业中的天然气或加工空气的专用应用的膨胀机 - 压缩机提出了建议。 ISO 10439-1:2015规定了适用于所有这些机器的一般要求。 ISO 10439-1:2015不适用于风扇（API 673涵盖）或发动机压力超过大气压力超过34 kPa（5 psi）的鼓风机。它也不适用于API 672所覆盖的包装，整体齿轮离心设备和仪表空气压缩机。超过300°C（570°F）的热气膨胀机不在ISO 10439-1:2015中。 ISO 10439-1:2015包含与ISO 10439其他部分所涵盖的所有设备相关的信息。它应与ISO 10439的以下部分一起使用，适用于所涉及的具体设备: 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
