Overview

EN IEC 60665:2019 specifies methods for measuring the performance of A.C. ventilating fans and associated regulators for household and similar purposes. It covers fans driven by single‑phase AC motors with power consumption less than 125 W (including regulators) intended for single‑phase AC circuits up to 250 V. The standard applies to common types such as partition (wall/window) fans and duct fans, and defines the required performance tests and ratings used for product specification and verification.

Key topics

• Scope and definitions - classification of ventilating fan types (Type A: partition, Type B: free‑inlet partition, Type C: free‑outlet partition, Type D: fully ducted) and fundamental terms (air delivery, fan inlet/outlet diameter, fan pressure, rated values).
• Performance tests - methods for measuring air delivery (volume flow rate) and fan pressure, with environmental and electrical test conditions (test voltage and frequency limits).
• Test installations - normative guidance (including Annex A) for test chambers and ducts used to evaluate air delivery for different fan types and arrangements.
• Components and ratings - requirements related to bearings, speed regulators, marking, and tolerances on fan ratings.
• Normative references - e.g., ISO 5801:2007 (industrial fan performance testing) is referenced for standardized airways and related procedures.
• Exclusions noted - this document does not cover safety (IEC 60335‑2‑80), comfort fans (IEC 60879), range hoods (IEC 61591), airborne acoustic noise testing (IEC 60704‑2‑7), or electromagnetic compatibility (CISPR/IEC EMC standards).

Applications / Who uses this standard

• Manufacturers - to design, rate and certify low‑power AC ventilating fans and integrated regulators for household applications; to publish reliable performance data.
• Test laboratories - to perform standardized air delivery and pressure measurements using the described test chambers and methods.
• Product certification bodies and compliance engineers - to assess conformity of fan performance claims for market entry within CENELEC/IEC markets.
• HVAC designers, specifiers and procurement teams - to compare fan performance (airflow, pressure) and select appropriate partition or duct fans for ventilation tasks.
• R&D and quality teams - for performance validation, benchmarking, and optimization of motor, impeller and regulator combinations.

Related standards

• Normative reference: ISO 5801:2007 (industrial fans - performance testing).
• Standards explicitly excluded or complementary:
  • IEC 60335‑2‑80 (safety of household fans)
  • IEC 60879 (comfort fans)
  • IEC 61591 (range hoods)
  • IEC 60704‑2‑7 (airborne acoustic noise)
  • CISPR 14‑1 / 14‑2, IEC 61000‑3‑2 / 61000‑3‑3 (EMC and mains compatibility)

A.C. VENTILATING FANS AND REGULATORS FOR HOUSEHOLD AND
SIMILAR PURPOSES – METHODS FOR MEASURING PERFORMANCE

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in
addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses
arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60665 has been prepared by subcommittee 59L: Small household
appliances, of IEC technical committee 59: Performance of household and similar electrical
appliances
This second edition cancels and replaces the first edition published in 1980. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) the test chambers have been updated;
b) a test chamber for a type D fan is introduced.
The text of this International Standard is based on the following documents:
