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 60704-2-14 is published under the responsibility of IEC technical
committee 59: Performance of household and similar electrical appliances.
It cancels and replaces International Standard ISO 8960 prepared by ISO technical committee
86: Refrigeration and transferred to the IEC subsequent to IEC/SMB decision 127/11.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The list of all the parts of the IEC 60704 series, under the general title Household and similar
electrical appliances – Test code for the determination of airborne acoustical noise, can be
found on the IEC website.
60704-2-14 © IEC:2007 – 3 –
This Part 2-14 is intended to be used in conjunction with the second edition (1997) of
IEC 60704-1: Household and similar electrical appliances – Test code for the determination of
airborne acoustical noise – Part 1: General requirements.
The relevant text of Part 1 as amended by this publication establishes the test code for
refrigerators, frozen-food storage cabinets and food freezers.
This Part 2-14 supplements or modifies the corresponding clauses in IEC 60704-1. When a
particular subclause of Part 1 is not mentioned in this Part 2-14, that subclause is applicable
as far as reasonable. Where this standard states “addition”, “modification” or “replacement”,
the relevant requirements, test specifications or explanatory matter in Part 1 should be
adapted accordingly.
Subclauses or figures that are additional to those in Part 1 are numbered starting from 101.
Additional annexes are lettered AA, BB, etc.
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in
the data related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –
TEST CODE FOR THE DETERMINATION OF
AIRBORNE ACOUSTICAL NOISE –
Part 2-14: Particular requirements for refrigerators, frozen-food
storage cabinets and food freezers

1 Scope
This part of IEC 60704 specifies methods for measuring airborne acoustical noise emitted by
electric refrigerators, frozen-food storage cabinets, food freezers and their combinations for
household and similar uses, supplied from the mains or from batteries.
The term "similar use" means "use under conditions similar to those in a household", for
example, in cafés, restaurants, hotels, and similar establishments.
This standard does not apply to appliances, equipment or machines designed exclusively for
industrial or commercial purposes.
This standard is concerned with objective methods of engineering accuracy (engineering
method, grade 2, according to IS0 2204) for determining sound power levels, (L expressed
W
in decibels with reference to a sound power of 1 pW, of airborne acoustical noise within the
specified frequency range of interest, and for specified operating conditions of the appliance
to be measured.
The frequency range of interest includes the octave bands with centre frequencies between
125 Hz and 8 000 Hz (this interval being, for practical reasons, narrower than the frequency
range of audible sound).
The following sound power levels are used:
– A-weighted sound power level, L ;
WA
– octave band sound power levels, L .
WOct
In general, the methods described are specified for appliances operated with no operator
present.
The noise measurements are made while the compressors are running.
Requirements as to an indication of the noise emission values are not the subject of this
standard.
NOTE 1 The uncertainties of measurement according to this standard usually result, for A-weighted sound power
levels, in standard deviations generally not exceeding approximately 2 dB, provided that the noise spectrum does
not contain pronounced discrete frequencies; if it does, the magnitude of the uncertainties will be larger. The
standard deviations referred to reflect the cumulative effects of all causes of measurement uncertainties, excluding
variations in the noise level of the appliance from test to test.
NOTE 2 The noise values obtained under the conditions described in this standard will not necessarily
correspond with the noise experienced under the operational conditions of practical use (see 6.4.1).
NOTE 3 For quality control during production, etc., simplified methods may be appropriate. For noise control
purposes (for example, development of quieter appliances, insulation of equipment, etc.), other measurement
methods using, for example, narrow-band frequency analysis will usually have to be applied. These methods are
not covered in this standard.
60704-2-14 © IEC:2007 – 5 –
This standard does not include methods for determining sound power levels with precision
accuracy (precision method, grade 1, according to IS0 2204) specified, for example, in IS0
3741, IS0 3742 and IS0 3745; they may, however, be applied if the appropriate
instrumentation and test environments are available.
