Clothes washing machines for household use - Methods for measuring the performance (IEC 60456:2010, modified)
Clothes washing machines for household use - Methods for measuring the performance (IEC 60456:2010, modified)
This International Standard 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 (washerdryers) with respect to their washing related functions. This International Standard also covers washing machines which specify the use of no detergent for normal use. 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.
Waschmaschinen für den Hausgebrauch - Verfahren zur Messung der Gebrauchseigenschaften (IEC 60456:2010, modifiziert)
Machines à laver le linge pour usage domestique - Méthodes de mesure de l'aptitude à la fonction (CEI 60456:2010, modifiée)
L'IEC 60456:2010 spécifie les méthodes de mesure de l'aptitude à la fonction des machines à laver le linge à usage domestique, avec ou sans dispositif de chauffage et alimentées en eau froide et/ou en eau chaude. Elle traite également des appareils à essorer le linge par la force centrifuge (essoreuses centrifuges). De même, elle est applicable aux appareils destinés à laver et sécher le linge (machines lavantes-séchantes) pour ce qui concerne leurs fonctions relatives au lavage. La présente Norme internationale couvre également les machines à laver spécifiées comme n'utilisant pas de détergent en utilisation normale.
L'aptitude à la fonction des sèche-linge est évaluée selon l'IEC 61121.
L'objet de la présente norme est d'établir et de définir les caractéristiques principales d'aptitude à la fonction des machines à laver électriques à usage domestique et de décrire les méthodes d'essai et de mesure de ces caractéristiques.
La présente Norme internationale s'applique également aux machines à laver à usage collectif dans les immeubles ou les laveries automatiques. Elle ne s'applique pas aux machines à laver des blanchisseries. La présente Norme internationale n'est pas destinée à être utilisée dans le cadre d'une évaluation comparative de détergents.
La présente Norme internationale ne spécifie pas les exigences relatives au bruit applicables aux machines à laver. Les mesures de bruit sont spécifiées dans l'IEC 60704-1 et l'IEC 60704-2-4.
La présente Norme internationale ne spécifie pas les exigences de sécurité applicables aux machines à laver. Les exigences de sécurité sont spécifiées dans l'IEC 60335-2-7.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente.
- Modification de l'exigence de masse de la charge d'essai dans le cas où la capacité assignée de la machine d'essai n'est pas déclarée. La détermination de la masse de la charge d'essai dans le cas où la capacité assignée n'est pas déclarée a été modifiée afin de supprimer l'ambiguïté de l'édition 4 et d'encourager cette déclaration.
- Introduction d'une option d'eau douce.
- Extension des salissures employées (pour l'évaluation de l'aptitude au lavage).
- Amélioration de la méthode de chargement et de pliage des articles de charge d'essai pour une meilleure adaptation aux machines à axe vertical, à axe horizontal et à double cuve.
- Révision et amendement des spécifications de la machine de référence reflétant toutes les qualifications de la nouvelle Electrolux Wascator CLS.
- Nouveaux programmes de référence pour les systèmes à axe vertical et basses températures. Nouvelle annexe informative comparant les programmes de référence aux programmes domestiques types.
- Affinage de la méthode d'efficacité du rinçage.
- Introduction de modes "arrêt" et "marche" basse puissance (pour l'évaluation de la consommation d'énergie).
- Nouvelle annexe relative à l'incertitude des mesures.
Gospodinjski pralni stroji - Metode za merjenje funkcionalnosti (IEC 60456:2010, spremenjen)
Ta mednarodni standard določa metode za merjenje funkcionalnosti gospodinjskih pralnih strojev z napravami za ogrevanje in oskrbo s hladno in/ali toplo vodo ali brez nje. Prav tako obravnava naprave za črpanje vode s centrifugalno silo (centrifuge)in velja za naprave za pranje in sušenje tekstila (pralno-sušilni stroji) glede njihove pralne funkcionalnosti. Ta mednarodni standard prav tako zajema pralne stroje, ki določajo normalno delovanje brez uporabe detergenta. Cilj je navesti in opredeliti glavne lastnosti funkcionalnosti električnih gospodinjskih pralnih strojev in centrifug in opisati standardne metode za merjenje teh lastnosti.

Foreword
The text of the International Standard IEC 60456:2010, prepared by SC 59D, Home laundry ap-
pliances, of IEC TC 59, Performance of household and similar electrical appliances, together
with common modifications prepared by the Technical Committee CENELEC TC 59X, Perform-
ance of household and similar electrical appliances, was submitted to the formal vote and was
approved by CENELEC as EN 60456 on 2011-03-21.
This document supersedes EN 60456:2005 + A11:2006 + A12:2011
Significant technical differences are
a) a test procedure for a combined test sequence of cotton 40 °C and cotton 60 °C with full
load and partial load is introduced,
b) a test procedure for measuring power consumption in low power modes is introduced,
c) a formula to calculate the energy consumption of washing machines including low power
modes is added,
d) the detergent dosage is reduced to 75 % for cotton and synthetic/blends,
e) the detergent dosage of the reference machine type 1 is adjusted to maintain the washing
performance level of the reference machine type 2,
f) the reference machine type 1 is to be used for testing according to Commission Regula-
tions with regard to energy labelling and ecodesign,
g) control procedures for checking measured values in comparison to values declared by the
manufacturer under consideration of permitted tolerances are updated.
The procedures described in this European Standard were modified substantially compared to
EN 60456:2005, e.g. with regard to detergent dosage. Therefore results of tests according to
this standard cannot and shall not be directly compared to results of similar procedures of pre-
vious versions. Also results based on a specific reference programme shall not be compared to
results based on other reference programmes.
