Household and similar electrical appliances - Test code for the determination of airborne acoustical noise - Part 2-4: Particular requirements for washing machines and spin extractors (IEC 60704-2-4:2011, modified); German version EN 60704-2-4:2012
Elektrische Geräte für den Hausgebrauch und ähnliche Zwecke - Prüfvorschrift für die Bestimmung der Luftschallemission - Teil 2-4: Besondere Anforderungen an Waschmaschinen und Wäscheschleudern (IEC 60704-2-4:2011, modifiziert); Deutsche Fassung EN 60704-2-4:2012
Overview
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. The measuring conditions specified in this Part 2-4 provide for sufficient accuracy in determining the noise emitted and comparing the results of measurements taken by different laboratories, whilst simulating as far as possible the practical use of household washing machines and spin extractors. The following modifications have been made with respect to DIN EN 60704-2-4:2002-05: a) measurement uncertainty and standard deviations are taken into account, b) definitions of standard test load and standard test program are modified, c) test enclosure was replaced by common test enclosure defined in Part 1; d) information to be reported is modified. The responsible committee is DKE/UK 513.1 "Wäschepflegegeräte" ("Laundry machines") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
