Full title and description

Vacuum technology — Turbomolecular pumps — Measurement of performance characteristics. This International Standard specifies methods for measuring the performance characteristics of turbomolecular pumps (all sizes and types, with mechanical or magnetic bearings, with or without drag stages).

Abstract

ISO 5302:2003 defines standardized test procedures and reporting for the determination of key performance parameters of turbomolecular pumps, enabling comparable measurement of pumping speed, throughput and related characteristics across manufacturers and test laboratories. The document was published as Edition 1 in 2003.

Scope

ISO 5302:2003 applies to methods for measuring working/performance characteristics of turbomolecular pumps regardless of size or bearing type (mechanical or magnetic) and whether an additional drag stage is present. It sets out measurement approaches intended to produce repeatable, comparable results for manufacturers, test houses and users of turbomolecular vacuum pumps.

Key topics and requirements

• Standardized measurement of pumping speed and throughput for turbomolecular pumps.
• Procedures for characterizing compression ratios and performance at varying backing pressures and gas species.
• Test configurations covering pumps with mechanical or magnetic bearings and with/without drag stages.
• Requirements for test reporting to enable comparison between different pumps and laboratories.
• Guidance to ensure measurements are traceable and reproducible across test facilities.

Typical use and users

Used by turbomolecular pump manufacturers for product characterization and data sheets, independent test laboratories and calibration facilities for performance verification, procurement and specification engineers evaluating pumps for vacuum systems, and research institutions comparing pump technologies and configurations.

Related standards

ISO 5302:2003 is part of the ISO vacuum-technology family and has been superseded in practice by later, more comprehensive methods in the ISO 21360 series (standard methods for measuring vacuum-pump performance), notably ISO 21360-4 which covers turbomolecular vacuum pumps. Other related ISO documents in vacuum technology (published or under the technical committee ISO/TC 112) cover pump performance, gauges and specific pump types and tests (for example, standards on rapid-shutdown torque and new parts of the ISO 21360 series).

FAQ

Q: What is this standard?

A: ISO 5302:2003 is an International Standard that specified methods for measuring the performance characteristics of turbomolecular pumps.

Q: What does it cover?

A: It covers standardized measurement procedures and reporting for turbomolecular-pump performance (pumping speed, throughput, compression behavior and related characteristics) applicable to pumps of all sizes and bearing types, with or without drag stages.

Q: Who typically uses it?

A: Pump manufacturers, independent test and calibration laboratories, procurement/specification engineers and researchers working with high‑ and ultra‑high vacuum systems commonly used the standard for consistent performance data.

Q: Is it current or superseded?

A: ISO 5302:2003 has been withdrawn. Measurement and reporting of turbomolecular pump performance are now covered by later parts of the ISO 21360 series (see ISO 21360‑4 for turbomolecular pumps), which provide updated, harmonized test methods.

Q: Is it part of a series?

A: ISO 5302:2003 belongs to the body of ISO vacuum-technology work developed under ISO/TC 112; its subject matter is now encompassed within the broader ISO 21360 series of standards for measuring vacuum-pump performance.

Q: What are the key keywords?

A: turbomolecular pump, vacuum technology, pumping speed, throughput, compression ratio, test methods, ISO 5302, ISO 21360.
