This chapter of GB/T 4214.1-2000 is applicable except as follows:
1.1 Applicable scope
1.1.1 General
Replacement:
This part is applicable to single unit electric washing machines, the washing and spinning function of combined appliances for household and similar use, and to spin extractors.
Limitations for the use of the test method involved in this part are given in 1.1.1 of GB/T 4214.1-2000.
Note: This part is not applicable to the noise measurement for drying function.
1.1.2 Types of noise
Replacement:
GB/T 6881.2, GB/T 6881.3 and GB/T 3767 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 GB/T 3767 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 6881.2-2002 and GB/T 6881.3-2002.
1.2 Object
Addition:
Requirements for the declaration of noise emission values are not within the scope of this part.
Note 3: For determining and verifying noise emission values declared in product specifications, see IEC 60704-3.
