Introduction of GB/T 4214.18-2024

GB/T 4214.18-2024 Test method for noise of household and similar electrical appliances - Particular requirements for washer-dryers 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 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 GB/T 6881.2-2017, GB/T 6881.3-2002 and GB/T 3767-2016 can be used for measuring noise emitted by washer-dryers. 1.1.3 Size of the source Replacement: The method specified in GB/T 3767-2016 is applicable to noise sources of any size. When applying GB/T 6881.2-2017 and GB/T 6881.3-2002, care should be taken that the maximum size of the washer-dryers under test fulfils the requirements specified in 1.2 of GB/T 6881.2-2017 and 1.3 of GB/T 6881.3-2002.. 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 specifications, 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. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. This clause of GB/T 4214.1-2017 is applicable except as follows: Addition: GB/T 3767-2016 Acoustics - Determination of sound power levels and sound energy levels of noise sources using sound pressure - Engineering methods for an essentially free field over a reflecting plane GB/T 6881.2-2017 Acoustics - Determination of sound power levels and sound energy levels of noise sources using sound pressure - Engineering methods for small movable sources in reverberant fields - Comparison method for a hard-walled test room IEC 60456:2010 Clothes washing machines for household use - Methods for measuring the performance 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. This clause of GB/T 4214.1-2017 is applicable except as follows: Addition: 3.101 washer-dryer household or similar electrical appliance for washing, rinsing and spinning of textiles that also provides a means for extracting excess water from the textiles by tumbling in a rotating drum, through which heated air is passed Note: This definition is similar to IEC 60456:2010, 3.1.4. 3.102 rated washing capacity maximum mass of conditioned textiles, in kg, which the manufacturer declares can be treated in one complete washing cycle [SOURCE: GB/T 38610-2020, 3.1.1, modified.] 3.103 rated drying capacity maximum mass of conditioned textiles, in kg, which the manufacturer declares can be treated in one complete drying cycle [SOURCE: GB/T 38610-2020, 3.1.2, modified.] 3.104 rated washing-drying capacity maximum mass of conditioned textiles, in kg, which the manufacturer declares can be treated in one continuous operation cycle [SOURCE: GB/T 38610-2020, 3.1.3, modified.] 3.105 cotton test load textile load consisting of towels only as defined in Annex C of IEC 60456:2010 3.106 washing period operating period that begins at the first water filling of the main wash and ends at the start of the drainage pump before the first rinsing operation Note: Options such as "pre-wash" are not included in the washing period.
