INTERNATIONAL ELECTROTECHNICAL COMMISSION
___________
HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –
TEST CODE FOR THE DETERMINATION OF AIRBORNE ACOUSTICAL NOISE –
Part 2-13: Particular requirements for range hoods
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this international standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60704-2-13 has been prepared by IEC technical committee 59:
Performance of household electrical appliances.
The text of this standard is based on the following documents:
FDIS Report on voting
59/230/FDIS 59/234/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
Annex AA is for information only.
This part 2-13 is intended to be used in conjunction with IEC 60704-1, second edition, 1997:
Household and similar electrical appliances – Test code for the determination of airborne
acoustical noise – Part 1: General requirements.
60704-2-13 IEC:2000 – 7 –
The relevant text of Part 1 as amended by this standard establishes the test code for range
hoods.
Clauses in this part 2-13 supplement or modify the corresponding clauses in IEC 60704-1.
When a particular subclause of part 1 is not mentioned in this part 2-13, that subclause applies
as far as reasonable. Where this standard states "addition", "modification" or "replacement",
the relevant requirement, test specification or explanatory matter in part 1 shall be adapted
accordingly.
Subclauses or figures which 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 2002. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

INTRODUCTION
The measuring conditions specified in this part 2-13 provide for sufficient accuracy in
determining the noise emitted and comparing the results of measurements taken by different
laboratories, whilst simulating as far as possible the practical use of household range hoods.
It is recommended to consider the determination of noise levels as part of a comprehensive
testing procedure covering many aspects of the properties and performance of household
range hoods.
NOTE As stated in the introduction to IEC 60704-1, this test code is concerned with airborne noise only.
An intensity method for measuring noise of range hoods is under consideration.

HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –
TEST CODE FOR THE DETERMINATION OF AIRBORNE ACOUSTICAL NOISE –
Part 2-13: Particular requirements for range hoods
1 Scope and object
This clause of part 1 is applicable except as follows:
1.1 Scope
1.1.1 General
Replacement:
These particular requirements apply to electrical range hoods (including their accessories and
their component parts) for household and similar use.
By similar use is understood the use in similar conditions as in households, for example in
inns, coffee-houses, tea-rooms.
These particular requirements apply to range hoods intended for filtering the air of the room or
for exhausting the air out of the room.
These particular requirements do not apply to:
– range hoods for industrial or professional purposes;
– appliances in which the fan is located in a separate unit from the range hood itself.
1.1.2 Types of noise
Addition:
ISO 3743-1, ISO 3743-2 and ISO 3744 can be used for measuring noise emitted by range
hoods.
1.1.3 Size of the source
Replacement:
The method specified in ISO 3744 is applicable to noise sources of any size. When applying
ISO 3743-1 and ISO 3743-2, care should be taken that the maximum size of the range hood
under test fulfils the requirements specified in 1.3 of ISO 3743-1 and ISO 3743-2.
60704-2-13 IEC:2000 – 13 –
1.2 Object
Addition:
This standard describes the determination of the noise emission of household range hoods
under normal operating conditions and at the highest fan speed setting for normal use (see
notes 1 and 2). If desired, this test method may be used at any fan speed setting.
NOTE 1 If a boost position is incorporated, this is not taken into account. (See 6.5 of IEC 61591.)
NOTE 2 A boost position is a setting of a control for occasional use which results in a higher temporary fan speed
(see 6.5 of IEC 61591).
Requirements for the declaration of noise emission values are not within the scope of this
standard.
NOTE 3 For determining and verifying noise emission values, declared in product specifications, see IEC 60704-3.
2 Normative references

Addition:
NOTE If pure tone components are present in the noise emitted, proper precautions should be taken as specified
in ISO 3743-2.
4.3 Comparison method
Addition:
NOTE If pure tone components are present in the noise emitted, proper precautions should be taken as specified
in ISO 3743-1 and ISO 3743-2.
5 Instrumentation
This clause of part 1 is applicable except as follows:
5.1 Instrumentation for measuring acoustical data
Addition:
The use of a windscreen is recommended and, if necessary, corrections for changes in the
microphone sensitivity shall be added to the observed sound pressure levels.
6 Operation and location of appliances under test
This clause of part 1 is applicable except as follows:
6.1 Equipping and pre-conditioning of appliances
6.1.1 Addition:
Recirculating-air range hoods should be fitted with a clean filter(s).
Air-extraction range hoods shall be fitted with the pipe coupling ring, if any, having the largest
diameter among those provided by the manufacturer. If the range hood is designed to
accommodate additional filters, those filters shall be clean and appropriately fitted.
6.1.3 Replacement:
Prior to noise measurements, the range hood shall have been in operation for running in for at
least 4 h at the highest speed setting for normal use (see notes in 1.2).
6.1.4 Replacement:
Immediately before each series of noise measurements, the range hood equipped for its
intended use is operated for stabilizing at the highest speed setting for normal use (see notes
in 1.2) for 30 min.
