Overview
EN ISO 10442:2002 (ISO 10442:2002) specifies requirements and recommendations for constant‑speed, packaged, integrally geared centrifugal air compressors used in the petroleum, chemical and gas service industries. The standard covers design, materials, fabrication, inspection, testing and preparation for shipment of packaged machines and their accessories. It also applies to other non‑hazardous, non‑toxic gas services but excludes devices that develop a pressure rise of less than 35 kPa (classified as fans or blowers).
Key topics and technical requirements
- Scope & applicability: Focus on packaged, integrally geared centrifugal air compressors for petroleum, chemical and gas applications; clarifies limits (non‑hazardous gases, ≥35 kPa pressure rise).
- Design principles: Requirements for basic package layout, integrally geared compressor assemblies (bull gear, pinions), driver selection and driver‑to‑compressor coupling.
- Materials & fabrication: Guidance on material selection and manufacturing practices for major components to ensure reliability in process environments.
- Accessories: Specifications for typical compressor accessories such as intercoolers, aftercoolers, inlet filters/silencers and discharge blowoff silencers.
- Inspection & testing: Inspection criteria, factory tests and performance verification procedures prior to shipment.
- Preparation for shipment: Packaging, preservation and documentation requirements to protect equipment in transit to refinery, plant or offshore site.
- Vendor data & documentation: Required proposal and contract data, plus informative annexes (data sheets, material specifications, diagrams, forces & moments) to support procurement and engineering.
- Safety & monitoring references: Cross‑references to standards for vibration and monitoring, hazardous area classification and performance testing.
Practical applications and users
EN ISO 10442:2002 is intended for:
- Compressor manufacturers designing and certifying packaged integrally geared centrifugal air compressors.
- Engineering, procurement and construction (EPC) firms specifying compressors for refineries, petrochemical plants and gas processing facilities.
- Plant operators and maintenance teams using the standard to evaluate vendor offerings, inspection/testing regimes, and spare‑parts compatibility.
- Procurement and QA personnel who require standardized vendor data sheets, test reports and shipment preparation practices.
Practical benefits include improved equipment interchangeability, clearer contractual requirements, and increased operational reliability for air and clean gas compression in industrial process services.
Related standards
EN ISO 10442:2002 builds on and cross‑references other relevant standards such as ISO 10439, API Std 672, ISO 10436, ISO 10438, ASME PTC 10, API Std 670 and IEC 60079‑10 (hazardous area classification), which can be consulted for complementary requirements on performance testing, monitoring and electrical installations.
