UNCERTAINTY REPORTING OF MEASUREMENTS


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) 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.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC 62617, which is a technical report, has been prepared by subcommittee 59D: Home
laundry appliances, of IEC technical committee 59: Performance of household and similar
electrical appliances.
The text of this technical report is based on the following documents:
Enquiry draft Report on voting
59D/355/DTR 59D/356/RVC

Full information on the voting for the approval of this technical report 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 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.
A bilingual version of this publication may be issued at a later date.

INTRODUCTION
To encourage the efficient use of energy and other resources, National governments and
regional authorities have issued regulations, which mandate the provision of information to
consumers regarding the energy and water consumption of household appliances and
associated performance characteristics. This information is usually conveyed by labels
attached to appliances at the point of sale and also by brochures provided by manufacturers.
Methods for measuring declared values for energy and water consumption and performance
characteristics must be of sufficient accuracy to provide confidence to governments,
consumers and manufacturers. The accuracy of a test method is expressed in terms of bias
and precision. Precision, when evaluating test methods, is expressed in terms of two
measurement concepts: repeatability and reproducibility. Therefore, standard procedures are
required for determining the repeatability and the reproducibility of test methods developed by
technical committee 59 and its subcommittees. The repeatability of a test method must be
sufficiently accurate for comparative testing. The reproducibility of a test method must be
sufficiently accurate for the determination of values which are declared and for checking these
declared values.
Uncertainty reporting is essential to ensure measured data are interpreted in a correct way.
Especially when data of measurements are to be compared between laboratories or when
normative requirements are set up, it is necessary to know the uncertainty with which data
can be measured.

1 Scope
This Technical Report (TR) applies to uncertainty reporting of home laundry electrical
appliances.
It allows to estimate the uncertainty of a measured result and to predict the range of values
that may be measured when the same appliance is measured in another laboratory following
the same measurement method.
NOTE The provisions in this TR can also be used to evaluate other kinds of products.
