M/458 - Washing Machine

This Technical Specification provides a measurement and evaluation method for the determination of the representative maximum temperature reached inside the base load during the washing cycle of a washing machine or washer-dryer.
The mean maximum temperature within the base load is measured with three temperature sensors, which are attached to towels and/or pillowcases placed in different, representative locations inside the drum.
This Technical Specification does not provide a method for measuring a temperature for the evaluation of hygiene performance.

IEC 60704-2-4:2011 These particular requirements apply to single unit electrical washing machines and the washing and spinning function of combined appliances for household and similar use and to spin extractors for household and similar use. This third edition cancels and replaces the second edition (2001). Main changes are:  - 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 and  - information to be reported is modified.   This publication is to be read in conjunction with IEC 60704-1:2010.

This Technical Specification provides a method for the evaluation of the rinsing effectiveness of household clothes washing machines, washer dryers and commercial washing machines. The amount of residual linear alkylbenzene sulfonate surfactant (LAS) extracted from the unstained test swatches of the strips used in the washing performance test is determined. This is accomplished by measuring the ultraviolet (UV) light absorbance at the wavelength particular to LAS, a key ingredient of the detergent.
Assuming a fixed linear relationship between LAS amount and quantity of detergent mixture and using a concentration versus absorbance curve developed as part of this procedure, the absorbance values are then converted into detergent concentrations, which together with the test solution mass data, yields detergent quantities. This assumption is done, because in the frame of this test it is not possible to determine the exact amount of LAS involved, even in the concentration curves, but only the amount of detergent used.
On the textiles, this linear relationship is not given, but it is nevertheless used to express the amount of LAS as determined by UV light absorbance measurements in terms of a detergent amount.
Using a concentration versus absorbance curve developed as part of this procedure, the absorbance values can then be converted into detergent concentrations, which together with the test solution mass data, yields detergent quantities.

IEC 60456:2010(E) specifies methods for measuring the performance of clothes washing machines for household use, with or without heating devices utilising cold and/or hot water supply. It also deals with appliances for water extraction by centrifugal force (spin extractors) and is applicable to appliances for both washing and drying textiles (washer-dryers) with respect to their washing related functions. This International Standard also covers washing machines which specify the use of no detergent for normal use. This edition includes the following significant changes from the previous edition. Modified test load mass requirement for cases where:
- rated capacity of test machine is not declared;
- introduction of soft water option;
- expanded stain/soil set;
- improved method of loading and folding test load items to better suit vertical axis, horizontal axis and twin tub systems;
- revised and amended reference machine specifications reflecting full qualification on new Electrolux Wascator CLS;
- new reference programmes for lower temperature and vertical axis systems;
- refined rinsing efficiency method;
- introduction of low power modes "OFF" and "Left On";
- new annex regarding uncertanity of measurements.

NOTE 1 Tumble dryer performance is assessed to IEC 61121.
The object is to state and define the principal performance characteristics of electric household washing machines and spin extractors and to describe the test methods for measuring these characteristics.
NOTE 2 This European standard applies also to washing machines for communal use in blocks of flats or in launderettes. It does not apply to washing machines for commercial laundries. This European Standard is not intended to be used for the comparative evaluation of detergents.
NOTE 3 This European Standard does not specify acoustical noise requirements for washing machines. Acoustical noise measurements are specified in IEC 60704-1 and IEC 60704-2-4.
NOTE 4 This European Standard does not specify safety requirements for washing machines. Safety requirements are specified in IEC 60335-2-7.
