Foreword

This amendment was prepared by WG 1, Washing machines, of the Technical Committee CENELEC
TC 59X, Consumer information related to household electrical appliances.

The text of the draft was submitted to the Unique Acceptance Procedure and was approved by CENELEC
as amendment A13 to EN 60456:1999 on 2002-12-03.

The following dates were fixed:

- latest date by which the amendment has to be implemented
 at national level by publication of an identical
 national standard or by endorsement (dop) 2003-06-01

- latest date by which the national standards conflicting
 with the amendment have to be withdrawn (dow) 2003-06-01

This amendment improves the reproducibility of the test method for the determination of the washing
efficiency of washing machines. It does not modify the test procedure in principle but specifies much more
precisely the test conditions. Modifications of IEC 60456 and IEC 61121 presently under consideration by
IEC/SC 59D are taken into account as far as possible.

It additionally introduces the common ambient conditions for washing machines, tumble dryers and
dishwashers.

In future the new reference detergent is called generally “ IEC A* “.

Annexes designated "normative" are part of the body of the standard.
Annexes designated "informative" are given for information only.
In this amendment, Annexes ZA, ZB, ZC, ZD and ZE are normative and Annex ZF is informative.
Annexes ZA to ZF have been added by CENELEC.

7 Materials
7.1.1 Cotton base load
Replace the first paragraph including the specifications of the sheets, pillowcases and hand towels as
follows:
The cotton base load shall consist of sheets, pillowcases and hand towels conforming with the
specifications given in Annex ZB.
Replace the last paragraph as follows:
An item shall not be used more than 80 cycles (not counting pre-treatment and the normalization
between two test series).
To minimise the influence of ageing of the textiles, the base load shall consist of items that are evenly
distributed in age for all different parts (sheets, pillowcases and hand towels) to give a weighted average
age of the load between 30 and 50 cycles, using the nominal weights given in Annex ZB. How the
average age of the load can be calculated is given in Annex ZE, examples how the textiles may be
exchanged are given in Annex ZF.
The age-distribution is to be reported.
7.2 Preparation of the base load
7.2.1 Preparation of textiles
Replace the first paragraph as follows:
New textile items shall be pre-treated before their first use by five normalisation processes according to
7.2.2 but using 15 g/kg of the reference detergent IEC A* followed by conditioning according to 7.2.3.
7.2.2 Normalisation of textiles
Replace the first paragraph by the following:
Wash the textiles in the Cotton 60 °C program of a reference washing machine without detergent.
7.2.3 Conditioning of textiles
Replace the present text by the following:
The textiles are left for at least 15 h in an ambient temperature of (20 ± 2) °C and at an ambient humidity
of (65 ± 5) % RH unless the weight of the load has changed less than 0,5 % between two successive
measurements. These measurements are carried out at two hour intervals.
As an alternative the bone-dry method of Annex F of EN 60456 may be used. After drying the textiles
have to be left at least 5 hours at ambient temperature according to 6.2.3 to take up water before being
used for tests.
If the bone-dry method is used, it shall be reported.

7.3 Soiled test strips
7.3.1 Characteristics
Add two new paragraphs before NOTE 1:
Washed soiled test strips shall fulfil the performance limits (ratios of Y-values) as defined in Annex ZC.
The storage conditions including deadline of use for soiled test strips shall be given by the manufacturer.
If no conditions are given the soiled test strips shall be kept vacuum packed in a refrigerator and shall be
used within 1 year after production.
8 Instrumentation and accuracy
8.1 Mass
Replace the sentence by the following:
The measurements shall be accurate to ± 0,1 %.
8.8 Electrical energy
Add the following paragraph at the end of the subclause:
Energy meters shall fulfil EN 61036 type 1 specification(s).
8.11 Optical reflectance
Replace the title and the text as follows:
8.11 Reflectance measurement for soiled test strips
Optical measurements of the different types of washed test strip specimens are made with a spectral
photometer. The measuring conditions are as indicated below:
Measuring instrument : spectral photometers that provide reflectance data at a minimum of sixteen
wavelengths spaced at 20 nm intervals or closer between 400 nm and 700 nm
Parameter : tristimulus value Y (CIE Nr. 15.2 , 1986)
Illuminant/observer : D65/10°
Measuring geometry : D/8°
UV filter : UV barrier at 420 nm, i.e. measurement without UV radiation
Measuring diameter : minimum 20 mm
Gloss/specular : excluded, i.e. measurement with open gloss/specular trap
Calibration : has to be done each time the spectral photometer is switched on or at least once per
working day:
white standard: barium sulphate tablet or ceramic tile;
black standard: black body.
For general handling of the device and for further information about calibration the
operation instruction for use shall be observed.

NOTE 1  The spectral photometer should be tested at least once a year for its operation efficiency.

Add the following new paragraphs at the end of the subclause:
Soiled test strips from the same batch shall be used for the reference machine and for the washing
machine under tests.
All handling of the load and the strips shall be equal. Both the reference machine and the machine under
test shall be loaded in the same way from bottom to top putting in all articles in a flat way. The detailed
procedure is described in ZD.4.
9.3.2 Cotton test load
Add a new paragraph after the NOTE:
The machines are loaded in the way as described in Annex ZD.

The reference machine shall perform a start up cycle before each cycle.
The machine under test shall be at ambient temperature before starting a cycle.
For energy label purposes only one cycle per day shall be done, unless it is verified that all parts of the
machine under test are at ambient temperature.
The dispenser, if any, of the machine under test and of the reference machine is cleaned and dried before
each cycle. It shall be ensured that in the reference machine the detergent is totally dispensed during the
water intake for the main wash.
th
Add to the present 4 paragraph (“After the completion of the washing program, all soiled test strips.) the
following sentence:
Washed and ironed soiled test strips are to be stored in the absence of light at ambient temperature
according to 6.2.3. until reflectance measurements are done.
Add a new NOTE:
NOTE 3 Instead of ironing, the strips can be stretched and rolled on an airy roll between two pieces of fabric, or be fastened to
hang in the dark.
Add in the first sentence of the last paragraph:
The reflectance measurements, performed according to 8.11, are carried out.
