A.C. ventilating fans and regulators for household and similar purposes - Methods for measuring performance

IEC 60665:2018 specifies the performance and the corresponding methods of test of AC ventilating fans for household and similar purposes intended for air forcing and exhaust, driven by single-phase AC motors having a power consumption of less than 125 W (including any associated regulators) for use on single-phase AC circuits not exceeding 250 V.
This document applies to ventilating fans such as partition fans for walls and windows and duct fans.
This document does not apply to:
- the safety of electric fans for household and similar purposes (IEC 60335-2- 80);
- the performance of comfort fans (IEC 60879);
- range hoods and other cooking fume extractors (IEC 61591);
- airborne acoustic noise for fans (IEC 60704-2-7);
- electromagnetic compatibility of fans (CISPR 14-1 and CISPR 14-2, IEC 61000-3-2, IEC 61000-3-3).
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.

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:
