Full title and description

St ISO 5802-2001 — Industrial fans — Performance testing in situ. This International Standard specifies tests and procedures for determining one or more performance characteristics of industrial fans while installed in their operational circuit (in situ), handling a single-phase (monophase) fluid, and defines required instrumentation, test conditions and reporting conventions for on-site performance verification.

Abstract

ISO 5802:2001 provides a standardized methodology for performing performance tests on fans in their installed configuration rather than in a dedicated test rig. It covers measurement of flow rate, total and static pressures, input power and derived parameters such as fan efficiency and performance curves, including requirements for instrumentation, calibration, test arrangement, corrections for ambient conditions and the format for reporting results. The standard was issued in 2001 and has at least one published amendment (2015) addressing clarifications and updates to the original text.

Scope

This standard specifies tests for determining one or more performance characteristics of industrial fans when they are installed in an operational circuit and are handling a single-phase fluid. It is intended for on-site performance measurement (in situ) rather than laboratory-type test rigs and covers the required measurement methods, instrumentation, test procedures, environmental corrections and reporting formats needed to produce comparable, repeatable performance data.

Key topics and requirements

• Definition of in situ test arrangements and minimum instrumentation (pressure, flow, and electrical power measurements).
• Procedures for measuring airflow (including use of differential-pressure flow meters and reference to ISO 5167 series where applicable).
• Methods for determining total and static pressures and for deriving fan performance (head/pressure vs. flow) and power/efficiency curves.
• Requirements for instrument calibration, measurement uncertainty assessment and traceability of results.
• Correction procedures for ambient conditions (temperature, pressure, density) and for test circuit effects.
• Reporting format and required information for test reports (test arrangement, instruments, measurement points, uncertainties and corrected performance data).
• Normative references to related standards (for example IEC 60034‑1 for rotating machines and ISO 5167 for flow measurement methods).

Typical use and users

ISO 5802:2001 is used by fan manufacturers, test laboratories, HVAC and industrial ventilation consultants, commissioning engineers, facility maintenance teams and procurement/acceptance inspectors. Typical applications include on-site acceptance testing after installation, performance verification during commissioning, troubleshooting of underperforming fan systems, and periodic performance monitoring to detect degradation or confirm compliance with contractual requirements.

Related standards

Commonly referenced or related standards include: - ISO 5167 (Measurement of fluid flow by means of pressure differential devices) for flow measurement methods; - IEC 60034-1 (rating and performance of rotating electrical machines) and IEC 60051‑8 for measurement instrumentation guidance; - EN ISO 5802:2008 (European adoption) and ISO 5802:2001/Amd 1:2015 (published amendment). These documents are frequently cited together with national/adopted versions of ISO 5802.

FAQ

Q: What is this standard?

A: ISO 5802:2001 is an International Standard that defines procedures and requirements for performance testing of industrial fans in their installed (in situ) configuration.

Q: What does it cover?

A: It covers test arrangements, required instrumentation and calibration, methods for measuring flow, pressures and electrical power, correction for ambient conditions, uncertainty assessment and the format and content of test reports for fans operating in installed circuits.

Q: Who typically uses it?

A: Fan manufacturers, test houses, HVAC and ventilation consultants, commissioning engineers, plant maintenance personnel and procurement/acceptance teams use the standard for on-site acceptance, troubleshooting and verification of fan performance.

Q: Is it current or superseded?

A: The 2001 edition remains the base published standard; it was amended by ISO 5802:2001/Amd 1:2015 and the ISO record shows the document was last reviewed/confirmed in 2023, so the 2001 edition with the 2015 amendment is treated as current (confirmed). Note that some national bodies have adopted EN ISO 5802 (2008) or have withdrawn earlier national copies in favor of the EN adoption—check the relevant national standards body for adoption/withdrawal status in your country.

Q: Is it part of a series?

A: ISO 5802 stands within the family of fan-related standards maintained by ISO/TC 117. It is used alongside other fan and flow measurement standards (for example ISO 5167 and ISO/IEC standards) to provide a complete framework for fan specification, testing and performance assessment.

Q: What are the key keywords?

A: Key keywords include industrial fan, in situ testing, performance testing, airflow, pressure, efficiency, commissioning, ISO 5802 and measurement uncertainty.
