Household and similar electrical appliances - Test code for the determination of airborne acoustical noise - Part 2-3: Particular requirements for dishwashers
|Publication Date:||1 April 2017|
|ICS Code (Noise emitted by machines and equipment):||17.140.20|
|ICS Code (Dishwashers):||97.040.40|
These particular requirements apply to single unit electric dishwashers for household and similar use, with or without automatic programme control, for cold and/or warm water supply, for detachable or permanent connection to water supply or sewage systems, intended for placing on the floor against a wall, for building-in or placing under a counter, a kitchen worktop or under a sink, for wall-mounting or on a counter.
Types of noise
The methods specified in ISO 3743-1, ISO 3743-2 and ISO 3744 can be used for measuring noise emitted by electric dishwashers.
Size of source
The method specified in ISO 3744 is applicable to noise sources of any size. When applying ISO 3743-1 and ISO 3743-2, care should be taken that the maximum size of the appliance under test fulfils the requirements specified in 1.2 of ISO 3743-1:2010 and 1.3 of ISO 3743- 2:1994.
Addition: Requirements for the declaration of noise emission values are not within the scope of this document.
NOTE 101 For determining and verifying noise emission values declared in product specifications, see IEC 60704-3.
The estimated values of standard deviations of sound power levels determined according to this document are given in Table 101:
Standard deviation for declaration and verification
For the purpose of determining and verifying declared noise emission values according to IEC 60704-3, the values in Table 102 apply:
