Foreword
The text of document 59D/379/CDV, future edition 3 of IEC 60704-2-4, prepared by IEC/SC 59D,
"Home laundry appliances", of IEC TC 59, "Performance of household electrical appliances", was
submitted to the IEC-CENELEC parallel vote and approved by CENELEC as EN 60704-2-4:2012.
A draft amendment, which covers common modifications to IEC 60704-2-4 (59D/379/CDV), was
prepared by CLC/TC 59X "Performance of household and similar electrical appliances" and approved
by CENELEC.
The following dates are fixed:
– latest date by which this document has to be (dop) 2013-04-13

This document supersedes EN 60704-2-4:2001.
EN 60704-2-4:2001:
measurement uncertainty and standard deviations are taken into account,
definitions of standard test load and standard test program are modified,
test enclosure was replaced by common test enclosure defined in Part 1,
information to be reported is modified.

6.101 Standard test programme for noise measurements
Replace this clause by the following:
The standard test programme for noise measurements is the standard 60 °C cotton programme for
normally soiled load provided by the manufacturer in the instruction manual.
If this programme is not available, then the most efficient 60 °C cotton programme for normally soiled
load without pre-wash according to the manufacturer’s instructions shall be used. Other special
options shall be deselected.
Highest available spin speed is to be chosen.
The standard test programme for noise measurements is carried out without detergent.
6.102.1 General
Replace this clause by the following:
The standard test load for noise measurements of washing machines consist of conditioned cotton
test load at a weight close to, but in any case not more than, the rated capacity.
To minimize the influence of changes in the characteristics of the cotton test load items with increasing
age, the standard test load shall consist of cotton test load items which are well distributed in age to
give an average age of the standard test load between 30 and 50 runs of the standard test
programme. The number of items or average age shall not be adjusted during a test series.
The average age of the standard test load is calculated as follows:
A = × n ×a
∑ i i
n
i
∑
where
a is the age of a single cotton test load item as the number of test runs after pre-treatment
i
as defined in 6.102.2;
n is the number of cotton test load items of the same age;
i
A is the average age of the standard test load expressed as the number of test runs.
Cotton test load items shall undergo normalisation as defined in 6.102.3 at least after have been used
10 runs of the standard test programme.
No test load item shall be used for more than 80 runs of the standard test programme, excluding pre-
treatment runs prior to initial use and normalisation runs.
