ISO 10442:2002

Overview

ISO 10442:2002 provides requirements and recommendations for the design, materials, fabrication, inspection, testing and preparation for shipment of constant‑speed, packaged, integrally geared centrifugal air compressors for the petroleum, chemical and gas service industries. It covers packaged units and their accessories, and also applies to non‑hazardous, non‑toxic gas services other than air. Machines with a pressure rise under 35 kPa (classified as fans or blowers) are excluded.

Key topics and technical requirements

• Scope and applicability: Defines covered equipment (packaged, integrally geared centrifugal compressors) and excluded machines (<35 kPa rise).
• Basic design: Requirements for package layout, pressure casing, intercoolers, driver selection (motor or turbine), and integrally geared compressor elements (bull gear, pinions).
• Package contents: Minimum equipment included in the package (compressor with integral gear, intercoolers, inlet throttle, driver, couplings and guards, lube‑oil system, vibration monitoring, controls, instrument panel, baseplate).
• Shipped‑loose accessories: Typical accessories that may be supplied loose (aftercooler, discharge check valve, inlet filter‑silencer, blowoff/by‑pass valve and silencer).
• Inspection, testing and shipment: Requirements and recommendations for inspection, performance testing and preparation for transport.
• Vendor data and documentation: Proposal and contract data, data sheets, and vendor responsibilities for providing specification details and deviations.
• Safety and operational definitions: Terms such as rated operating point, maximum allowable temperature/pressure, trip speed and standby service.
• Annexes and references: Informative annexes (data sheets, material specs, diagrams) and a normative annex covering forces and moments.

Practical applications and who uses it

ISO 10442 is intended for:

• OEMs and compressor manufacturers specifying and designing packaged integrally geared centrifugal compressors.
• Plant engineers and procurement teams in petroleum, petrochemical and natural gas facilities who prepare purchase specifications and evaluate vendor proposals.
• Commissioning, inspection and maintenance personnel who rely on standardized test, inspection and documentation requirements.
• Design and safety engineers assessing package suitability for environmental conditions, driver selection and protective systems.

Typical uses include preparing tender specifications, verifying vendor compliance, planning installation/transport, and ensuring equipment meets industry expectations for reliability and performance.
