Foreword
The text of the International Standard IEC 60456:2003, prepared by SC 59D, Home laundry
appliances, of IEC TC 59, Performance of household electrical appliances, together with the
common modifications prepared by the Technical Committee CENELEC TC 59X, Consumer
information related to household electrical appliances, was submitted to the formal vote and
was approved by CENELEC as EN 60456 on 2004-10-01.
This European Standard supersedes EN 60456:1999 + A11:2001 + A12:2001 + A13:2003.
Many of the changes in the new IEC 60456:2003 had already been included in
EN 60456:1999/A12:2001 and A13:2003. Consequently, the only significant technical
difference with the previous edition of the European Standard is the allowance of three
alternative methods to condition the load.
It is not expected that this new version EN 60456 will influence energy label declaration in any
way.
In this European Standard the common modifications to the International Standard are
indicated by a vertical line in the left margin of the text.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2005-10-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2007-10-01
In this standard, the following print types are used:
– test specifications: in italic type;
– notes: in small roman type;
– other text: in roman type.
– words in bold in the text are defined in Clause 3.
Clauses, subclauses and notes that are additional to those in IEC 60456 are prefixed with the
letter Z.
The contents of the corrigendum of March 2008 have been included in this copy.

1 Scope
This International Standard deals with methods for measuring the performance of clothes
washing machines for household use, with or without heating devices and for cold and/or hot
water supply. It also deals with appliances for water extraction by centrifugal force and is
applicable to appliances for both washing and drying textiles (called washer-dryers) with
respect to their washing performance.
The object is to state and define the principal performance characteristics of household
electric washing machines and spin extractors and to describe the standard methods for
measuring these characteristics.
This standard is concerned neither with safety nor with performance requirements.
NOTE 1 This standard applies also to washing machines for communal use in blocks of flats or in launderettes,
but washing machines for commercial laundries are not included.
NOTE 2 While this standard includes testing requirements for all types of washing machines, to date there has
been only limited testing and evaluation of other than horizontal drum washing machines to this standard.
This European Standard also specifies, as far as necessary, the test methods which shall be
applied in accordance with the Commission's Directive 95/12/EC of 23 May 1995
implementing Council Directive 92/75/EEC with regard to energy labelling of household
washing machines.
