Full title and description

St ISO 14695-2003 — Industrial fans — Method of measurement of fan vibration. This international standard specifies general methods for measuring vibrational characteristics of industrial fans (excluding simple air‑circulation fans such as ceiling and table fans), with practical guidance on measurement quantities, instrumentation and test arrangements for fans installed with power below 300 kW.

Abstract

ISO 14695:2003 describes procedures to measure fan vibration expressed as overall r.m.s. velocity, acceleration or displacement, or as frequency spectra over an appropriate frequency range. Test methods include measurements on fans suspended on elastic ropes and fans mounted on resilient supports. The standard is a general measurement method and does not provide interpretation criteria for acceptance levels (see related ISO 14694); a technical corrigendum to ISO 14695 was published in 2009.

General information

• Status: Published (International Standard; confirmed at subsequent systematic reviews).
• Publication date: April 2003 (ISO edition 1, 2003-04).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 17.160 (Vibrations, shock and vibration measurements); 23.120 (Fans, ventilators).
• Edition / version: Edition 1 (2003).
• Number of pages: 33 (English edition listing by ISO).

Scope

Applies to measurement of vibration characteristics of industrial fans of all types except those designed solely for air circulation (for example ceiling and table fans). The standard is limited to fans installed with a motor or driven‑power rating below 300 kW; for higher‑power fans, ISO 10816‑1 and ISO 10816‑3 are the referenced methods/limits. ISO 14695 provides measurement methodology only and does not specify pass/fail interpretation criteria.

Key topics and requirements

• Definition of measurement quantities: overall r.m.s. velocity, acceleration, displacement and frequency‑spectrum analysis.
• Recommended frequency ranges and instrumentation for capturing fan vibration signatures.
• Test arrangements for fans suspended on elastic ropes and for fans on resilient mountings (procedures for installed and suspended conditions).
• Guidance on measurement points and repeatability of tests; mounting forces at support points are acknowledged as useful but are outside the standard's scope.
• Reference to complementary standards for interpretation or alternative measurement limits (ISO 14694; ISO 10816 series).

Typical use and users

Used by fan manufacturers, test laboratories, vibration analysts, reliability and maintenance engineers, plant designers and certification bodies to establish consistent measurement practice for fan vibration during type testing, acceptance testing and condition monitoring. National standards bodies and providers of machinery testing services also reference this standard when specifying vibration measurement programs.

Related standards

Commonly used alongside ISO 14694 (guidance/interpretation for fan vibration data) and the ISO 10816 series (machine vibration — evaluation and limits for higher‑power machinery). A technical corrigendum was issued as ISO 14695:2003/Cor 1:2009 to correct/clarify elements of the 2003 text.

FAQ

Q: What is this standard?

A: ISO 14695:2003 is an international standard that defines methods for measuring the vibrational characteristics of industrial fans (excluding simple air‑circulation fans).

Q: What does it cover?

A: It covers procedures for measuring overall r.m.s. velocity, acceleration or displacement and frequency‑spectrum measurements, and includes test arrangements for fans suspended on elastic ropes and for fans on resilient mountings. It does not give criteria for interpreting results.

Q: Who typically uses it?

A: Fan manufacturers, test laboratories, vibration and reliability engineers, plant maintenance teams and standards committees use the standard to ensure consistent, repeatable vibration measurement methods.

Q: Is it current or superseded?

A: The 2003 edition remains the published international standard; it has been subject to systematic review and a technical corrigendum (ISO 14695:2003/Cor 1:2009) was issued. Users should check national adoption status and any later revisions or related ISO publications for updates.

Q: Is it part of a series?
