Overview

EN IEC 60704-2-2:2024 (based on IEC 60704-2-2:2023) is the Part 2-2 test code that defines particular requirements for determining airborne acoustical noise from electric fan heaters (floor, table, counter or mounted types). It is a technical revision (third edition) that supplements the general requirements in IEC 60704-1:2021 and is published by CLC/CENELEC as the European adoption of the international text.

This standard:

• Applies to fan heaters for household and similar use (excludes storage room heaters, room humidifiers/dehumidifiers, air cleaners, and industrial-only heaters).
• Specifies measurement environments, instrumentation notes and reporting requirements to ensure reproducible acoustical measurements.
• Introduces updated requirements on climatic conditions, background noise, and revised built‑in conditions to better reflect practical use and laboratory comparability.

Key Topics & Technical Requirements

• Scope & exclusions: Clarifies appliance types covered and explicitly lists excluded equipment.
• Use with IEC 60704-1:2021: Part 2-2 supplements or modifies corresponding clauses in the general Part 1 test code; unspecified subclauses of Part 1 remain applicable.
• Measurement methods: Accepts direct and comparison methods; refers to ISO standards (ISO 3743-1, ISO 3743-2, ISO 3744) for applicable acoustical environments and test setups.
• Measurement uncertainty: Provides estimated standard deviations for sound power levels:
  • Repeatability σr ≈ 0.4 dB
  • Reproducibility σR ≈ 1.0 dB
  • Declaration/verification related values: production σP 0.3–1.1 dB, total σt 1.0–1.6 dB, reference σM 1.5 dB
• Instrumentation: Recommends use of windscreens and applying corrections for microphone sensitivity changes.
• Reporting: Defines information to be recorded and reported to ensure consistent comparison between laboratories.

Practical Applications

• Routine laboratory testing of fan heater noise emissions for design validation, R&D and type testing.
• Supporting compliance and performance claims in product specifications (note: for formal declaration/verification see IEC 60704-3:2019).
• Benchmarking and competitive product comparisons, noise troubleshooting, and improving acoustic comfort in consumer products.
• Useful for manufacturers, test laboratories, acoustical consultants and regulatory bodies setting noise-related requirements.

Who Should Use This Standard

• Appliance manufacturers and design engineers producing fan heaters
• Accredited testing laboratories and QA teams performing noise measurements
• Compliance officers and product certification bodies
• Acoustical consultants advising on product noise 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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s),
which may be required to implement this document. However, implementers are cautioned that this may not
represent the latest information, which may be obtained from the patent database available at
https://patents.iec.ch. IEC shall not be held responsible for identifying any or all such patent rights.
IEC 60704-2-2 has been prepared by subcommittee 59C: Electrical heating appliances for
household and similar purposes, of IEC technical committee 59: Performance of household
and similar electrical appliances. It is an International Standard.
