Overview

EN 60704-2-5:2005 (adopting IEC 60704-2-5:2005) is the Part 2-5 supplement to the airborne acoustical noise test code for electric thermal storage room heaters. It specifies particular requirements for noise testing of forced‑convection storage heaters designed for floor placement, wall‑mounting or building‑in. The Part 2-5 document is intended to be used together with EN/IEC 60704-1 (general requirements) and focuses on practical, reproducible determination of airborne noise from these appliances.

Key topics and technical requirements

• Scope: Applies to electric thermal storage room heaters with forced convection; excludes natural‑convection controlled output heaters, free‑output heaters and central storage systems or parts.
• Measurement methods: Recommends use of ISO 3743‑1, ISO 3743‑2 and ISO 3744 for direct and comparison methods; notes special precautions when pure tones are present (see ISO 3743‑2).
• Frequency range: Sound power determination covers octave bands with centre frequencies from 63 Hz to 8 000 Hz (with special attention to room effects at 63 Hz).
• Test conditions:
  • Noise measurements are performed without heating (noise source is primarily the fan; heating cycles are long and may overheat test room/equipment).
  • Appliances must be assembled as the manufacturer specifies; air paths, louvers and filters must be clean.
  • Preconditioning: fans/blowers should run for at least 1 hour at the highest normal speed prior to noise measurement; filters may be removed during running‑in.
• Uncertainty and repeatability:
  • Estimated standard deviations for sound power: σ (repeatability) = 0.4 dB, σ (reproducibility) = 1.0 dB.
  • For declaration/verification (per IEC 60704‑3): production σ ≈ 0.7–1.1 dB, total σ ≈ 1.2–1.5 dB, reference σ ≈ 2.0 dB.
• Reporting: Specifies required measurement, calculation and reporting elements to ensure comparable results between laboratories.

Practical applications

• Type testing and product development to quantify fan and aerodynamic noise.
• Certification, product noise declaration and verification for compliance with noise labeling or procurement specifications.
• Comparative laboratory testing, quality control and production testing programs.
• Useful to HVAC and appliance manufacturers, independent acoustic test laboratories, regulatory bodies and procurement engineers.

Who uses this standard

• Appliance manufacturers (R&D and compliance teams)
• Accredited acoustical testing laboratories
• Regulatory authorities and conformity assessment bodies
• Product designers and procurement/specification engineers

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 60704-2-5 has been prepared by subcommittee 59C: Heating
appliances, of IEC technical committee 59: Performance of household electrical appliances.
This second edition cancels and replaces the first edition published in 1989 and constitutes a
technical revision. This revision has become necessary due to the publication of the second
edition of IEC 60705-1. Th
