DIN EN ISO 10439-1:2010-09

This International Standard 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. This part of ISO 10439 specifies general requirements applicable to all such machines. ISO 10439 does not apply to fans (these are covered by API STD 673) or blowers that develop less than 34 kPa (5 psi) pressure rise above atmospheric pressure. ISO 10439 also does not apply to packaged, integrally-geared centrifugal plant and instrument air compressors, which are covered by API STD 672. Hot gas expanders over 300 °C (570 °F) are not covered by ISO 10439. This part of ISO 10439 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: Part 2: Non-integrally geared centrifugal and axial compressors Part 3: Integrally geared centrifugal compressors Part 4: Expander-compressors
