IEC 60456-2003 pdf – Clothes washing machines for household use – Methods for measuring the performance.
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. 2 Normative references The following referenced documents are indispensable for the application of this document.

3 Terms, definitions, symbols and dimensions 3.1 Terms and definitions For the purposes of this document, the following definitions apply. 3.1.1 washing machine appliance for cleaning and rinsing of textiles using water which may also have a means of extracting excess water from the textiles 3.1.2 agitator washing machine washing machine in which the textiles are substantially immersed in the washing water, the mechanical action being produced by a device moving about or along its vertical axis with a reciprocating motion (an agitator). This device usually extends above the maximum water level 3.1.3 horizontal drum washing machine washing machine in which the textiles are placed in a horizontal or inclined drum and partially immersed in the washing water, the mechanical action being produced by rotation of the drum about its axis, the movement being either continuous or periodically reversed 3.1.4 impeller washing machine washing machine in which the textiles are substantially immersed in the washing water, the mechanical action being produced by a device rotating about its axis continuously or which reverses after a number of revolutions (an impeller). The uppermost point of this device is substantially below the minimum water level 3.1.5 nutator washing machine washing machine in which the textiles are placed in a vertical axis basket and partially immersed in the washing water, the mechanical action being produced by a nutation plate in the bottom of the basket, the movement being either continuous or periodically with or without reversion 3.1.6 washer-dryer washing machine which includes both a water extraction (spin) function and also a means for drying the textiles, usually by heating and tumbling 3.1.7 spin extractor water-extracting appliance in which water is removed from textiles by centrifugal action 3.1.8 spin extraction water-extracting function by which water is removed from textiles by centrifugal action.
3.1.9 base load textile load without soiled test strips 3.1.10 test load base load plus soiled test strips or wool shrinkage specimens 3.1.11 programme series of operations which are pre-defined within the washing machine and which are declared as suitable for washing certain textile types 3.1.12 cycle complete washing process, as defined by the programme selected, consisting of a series of different operations (wash, rinse, spin, etc.) 3.1.13 rated capacity maximum mass in kg of dry textiles of a particular defined type, declared by the manufacturer that can be treated in a programme
