INTERNATIONAL ELECTROTECHNICAL COMMISSION
____________
HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –
TEST CODE FOR THE DETERMINATION OF
AIRBORNE ACOUSTICAL NOISE –
Part 2-11: Particular requirements for electrically-operated
food preparation appliances
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 Org anization 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 60704-2-11 has been prepared by subcommittee 59L: Small
household appliances, of IEC technical committee 59: Performance of household electrical
appliances.
This second edition cancels and replaces the first edition published in 1998. This edition
constitutes a technical revision and includes the following significant technical changes with
respect to the previous edition:
a) definition of various kind of food preparation appliances added;
b) revision of the test conditions;
c) coffee mills and coffee grinders are removed from the scope.
This Part 2-11 is intended to be used in conjunction with the fourth edition (2021) of IEC 60704-
1, Household and similar electrical appliances – Test code for the determination of airborne
acoustical noise – Part 1: General requirements.
59L/254/CDV – 4 – IEC CDV 60704-2-11 © IEC 2024
The relevant text of IEC 60704-1:2021 as amended by this publication establishes the test code
for electrically-operated food preparation appliances.
This Part 2-11 supplements or modifies the corresponding clauses in IEC 60704-1:2021. When
a particular subclause of IEC 60704-1:2021 is not mentioned in this document, that subclause
is applicable as far as reasonable. Where this standard states "addition", "modification",
"replacement" or "deletion" the relevant requirements, test specifications or explanatory matter
in IEC 60704-1:2021 should be adapted accordingly.
Subclauses and tables that are additional to those in IEC 60704-1:2021 are numbered starting
from 101.
Unless notes are in a new subclause or involve notes in IEC 60704-1:2021, they are numbered
starting from 101, including those in a replaced clause or subclause.
A list of all the parts in 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.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this publication will remain unchanged until the
stability 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.

1 INTRODUCTION
2 The measuring conditions specified in this Part 2-11 provide for sufficient steadiness in the
3 noise emitted and reproducibility in different laboratories, whilst simulating as far as possible
4 the practical use of electrically-operated food preparation appliances.
5 It is recommended to consider the determination of noise levels as part of a comprehensive
6 testing procedure covering many aspects of the properties and performance of electrically-
7 operated food preparation appliances.
8 NOTE As stated in the introduction to IEC 60704-1:2021, this test code is concerned with airborne noise only.

18 Addition:
19 This standard applies to electrically-operated food preparation appliances, either in the form of
20 separate machines with a single function or in the form of multi-purpose machines with
21 appropriate tools or attachments for several functions. These machines are intended for placing
22 on counters, tables, work tops or sinks, for built-in, or for hand-held use, supplied from mains
23 or from batteries and able to ensure the functions described in clause 4 of
24 IEC 60619:1993 + AMD1:1995 + AMD2:2004.
