DIN EN ISO 10439-1:2015-05

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. This International Standard 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. This International Standard 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 this International Standard. 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: - ISO 10439-2; - ISO 10439-3; - ISO 10439-4. Regarding German collaboration at DIN the Working Committee is NA 109-00-01-06 AK "Verfahrenstechnische Anlagen und Ausrüstungen" ("Processing equipment and systems") of Standards Committee Petroleum and Natural Gas Industries (NÖG).
