IEC 60704-2-16-2019 pdf download.Household and similar electrical appliances – Test code for the determination of airborne acoustical noise – Part 2-16: Particular requirements for washer-dryers (IEC 60704-2-16:2019).
1 Scope and object
This clause of Part 1 is applicable except as follows:
1.1 Scope
1.1.1 General Addition: These particular requirements apply to single-unit electric washer-dryers for household and similar use 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.
1.1.2 Types of noise Replacement: The methods specified in ISO 3743-1, IsO 3743-2 and ISO 3744 can be used for measuring noise emitted by washer-dryers.
1.1.3 Size of the source Replacement: 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 washer- dryers under test fulfils the requirements specified in 1.2 of ISO 3743-1:2010 and 1.3 of ISO 3743-2:1994.
1.2 Object
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 specilications, see IEC 60704-3.
1.3 Measurement uncertainty Replacement: For washer-dryers, the estimated values of standard deviations of sound power levels, determined in accordance with this document are as indicated in Table 101 and 102.
1.101 Standard deviation for declaration and verification
For the purpose of determining and verifying declared noise emission values for washing and spinning for washer-dryers in accordance with IEC 60704-3, the values indicated in Table 103 apply.
For the purpose of determining and verifying declared noise emission values for drying for washer-dryers in accordance with IEC 60704-3, the values indicated in Table 104 apply.
