24、s possible the practical use of household range hoods. It is recommended to consider the determination of noise levels as part of a comprehensive testing procedure covering many aspects of the properties and performance of household range hoods. Compared to the first edition (2000) of this Part 2-13
25、, the second edition doesnt contain the description of an appropriate test enclosure which has now been incorporated in Part 1. The scope of this Part 2-13 has been extended to range hoods with an external fan. Furthermore the values of standard deviations of sound power levels determined according
26、to this part are given. In case of unavailability of an acoustical environment which is specified in Clause 4 of ISO 3743-1, ISO 3743-2 and ISO 3744 alternatively the sound power of range hoods can be determined according to Annex AA using the sound intensity method specified in ISO 9614-1 and ISO 9
27、614-2. This method is not suitable if the source under test has significant noise over 4,0 kHz for octave band frequencies or 6,3 kHz for one-third octave band frequencies. Sound intensity method for the determination of sound power levels shall not be used for the purpose of verification. NOTE As s
28、tated in the introduction to IEC 60704-1, this test code is concerned with airborne noise only.

29、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 electrical range hoods for household and similar use intended for filtering the air of a room or for exhausting the air out of a room, including their acce
30、ssories and their component parts. It also applies to range hoods with an external fan which may be mounted inside or outside of the room where the range hood is located. 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 em
31、itted by range hoods. 1.1.3 Size of 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 range hood under test fulfils the requirements specified in 1.3 of ISO 3743-
32、1 and ISO 3743-2. 1.2 Object Addition: This standard describes the determination of the noise emission of household range hoods under normal operating conditions and at the highest fan speed setting for normal use. NOTE 101 If a boost position is incorporated, this is not taken into account (see 6.5
33、 of IEC 61591). NOTE 102 A boost position is a setting of a control for occasional use, which results in a higher temporary fan speed (see 6.5 of IEC 61591). Requirements for the declaration of noise emission values are not within the scope of this standard. NOTE 103 For determining and verifying no
34、ise emission values declared in product specifications, see IEC 60704-3. 1.3 Measurement uncertainty Replacement: BS EN 60704-2-13:2011 6 60704-2-13 IEC:2011(E) The estimated values of standard deviations of sound power levels, determined according to this standard, are as follows: Table 101 Standar

The range hood can incorporate an internal or external fan. 4 Measurement methods and acoustical environments This clause of Part 1 is applicable except as follows: 4.2 Direct method Addition: NOTE 101 If pure tone components are present in the noise emitted by the source, the estimated standar
41、d deviation of the measured sound pressure levels in the special reverberation room may increase. In such cases additional microphone positions or source positions may be necessary as specified in ISO 3743-2. 4.3 Comparison method Addition: NOTE 101 If pure tone components are present in the noise e
42、mitted by the source, the estimated standard deviation of the measured sound pressure levels in the hard-walled test room or in the special reverberation room may increase. In such cases additional microphone positions or source positions may be necessary as specified in ISO 3743-1 or ISO 3743-2. 5
43、Instrumentation This clause of Part 1 is applicable except as follows: 5.1 Instrumentation for measuring acoustical data Addition: Windscreens should be used if necessary and then corrections for change in the microphone sensitivity shall be added to the observed sound pressure levels. 6 Operation a
44、nd location of appliance under test This clause of Part 1 is applicable except as follows: 6.1 Equipping and pre-conditioning of appliance 6.1.1 Addition: Recirculation-air range hoods should be fitted with a clean filter(s).
