Test method for noise of household and similar electrical appliances—
Particular requirements for washing machines and spin extractors
1 Scope and object
This clause of GB/T 4214.1-2017 is applicable except as follows:
1.1 Scope
1.1.1 General
Addition:
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.
Note 101: For drying function, see GB/T 4214.7.
1.1.2 Types of noise
Replacement:
The methods specified in GB/T 6881.2, GB/T 6881.3 and ISO 3744 can be used for measuring noise emitted by washing machines and spin extractors.
1.1.3 Size of the source
Replacement:
The method specified in ISO 3744 is applicable to noise sources of any size. When applying GB/T 6881.2 and GB/T 6881.3, care should be taken that the maximum size of the washing machine or spin extractor under test fulfills the requirements specified in 1.3 of GB/T 6881.2 and GB/T 6881.3.
1.2 Object
Addition:
Requirements for the declaration of noise emission values are not within the scope of this standard.
Note 101: For determining and verifying noise emission values declared in product specifications, see IEC 60704-3.
1.3 Measurement uncertainty
Replacement:
For washing machines, the estimated values of standard deviations of sound power levels, determined according to this standard, are as indicated in Table 101:
