31、ing the results of measurements taken by different laboratories, whilst simulating as far as possible the practical use of tumble dryers. It is recommended to consider the determination of noise levels as part of a comprehensive testing procedure covering many aspects of properties and performance o
32、f household tumble dryers. NOTE As stated in the introduction to IEC 60704-1, this test code concerns airborne noise only.

34、or placing under a counter, a kitchen worktop or under a sink, for wall-mounting or on a counter. For the purpose of this standard, washer-dryer combinations, when operated as a dryer, are considered as a tumble dryer. NOTE 101 For washing function, see IEC 60704-2-4. This standard is also applicabl
35、e for gas-fired electric tumble dryers. 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 tumble dryers. 1.1.3 Size of the source Replacement: The method specified in ISO 3744 is applicable to noise sources of an
36、y 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 1.3 of ISO 3743-1 and ISO 3743-2. 1.2 Object Addition: Requirements for the declaration of noise emission values are not within the scope of t
37、his standard. NOTE 101 For determining and verifying noise emission values declared in product specifications, see IEC 60704-3. 1.3 Measurement uncertainty Replacement: BS EN 60704-2-6:201260704-2-6 IEC:2012 7 The estimated values of standard deviations of sound power levels, determined according to
38、 this standard, are: Table 101 Standard deviations of sound power levels Standard deviation dB r(repeatability) R(reproducibility) 0,4 0,8 Addition: 1.101 Standard deviation for declaration and verification For the purpose of determining and verifying declared noise emission values according to IEC
