EN ISO 10439-1:2015 PDF

Overview

EN ISO 10439-1:2015 (ISO 10439-1:2015) - published by CEN/ISO - specifies the general requirements for axial compressors, single-shaft and integrally geared process centrifugal compressors, and expander‑compressors used for gas or process air in the petroleum, petrochemical and natural gas industries. Part 1 sets minimum requirements and recommendations that apply across the ISO 10439 series and is intended to be used with Parts 2–4 for equipment‑specific provisions.

This standard excludes:

• fans (covered by API 673),
• blowers developing less than 34 kPa (5 psi) pressure rise,
• packaged integrally geared centrifugal plants and instrument air compressors (covered by API 672),
• hot gas expanders exceeding 300 °C (570 °F).

Key topics and technical requirements

ISO 10439‑1:2015 establishes general engineering, safety and inspection expectations. Major technical areas include:

• Design fundamentals - units, statutory requirements, unit responsibility and basic design principles.
• Materials and fabrication - selection, castings, forgings and welding requirements.
• Casings and pressure parts - pressure-containing casings, repairs, inspections and material verification.
• Rotating elements - geometry, integrity and manufacture of rotors and disks.
• Dynamics and vibration - lateral/torsional analysis, stability levels, unbalanced rotor testing and dynamic verification.
• Bearings and seals - hydrodynamic bearings, thrust bearings, bearing housings, oil seals and dry gas seals.
• Integral gearing - requirements for integrally geared compressor arrangements.
• Accessories and auxiliaries - drivers, couplings, lubrication, controls, instrumentation, piping, mounting plates and baseplates.
• Testing, instrumentation and controls - instrumentation, alarms, shutdown systems, vibration and temperature detection.

The standard also addresses documentation, nameplates, external forces and casing support, and guidance on additional testing.

Applications and users

ISO 10439‑1:2015 is used by:

• OEMs and manufacturers of axial compressors, centrifugal compressors and expander‑compressors for process applications.
• Engineering procurement and construction (EPC) firms, plant designers and process engineers working in petroleum, petrochemical and natural gas facilities.
• Asset owners, operations, inspection and maintenance teams specifying compressor procurement, installation, commissioning and lifecycle maintenance.
• Regulatory and compliance teams ensuring statutory and industry-standard conformity.

Use ISO 10439‑1:2015 when specifying general performance, safety, material and testing criteria that will be supplemented by ISO 10439 Parts 2–4 for equipment-specific requirements.
