33、reezers (fitted with their accessories) for household and similar use, supplied from the mains or from batteries. 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 refrigerators, frozen-food storage cabinets and

34、food freezers. 1.1.3 Size of the 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 refrigerator, frozen-food storage cabinet or food freezer under test fulfils th

35、e requirements specified in 1.3 of ISO 3743-1 and ISO 3743-2. 1.2 Object Addition: These described methods are specified for appliances without an operator present. Requirements for the declaration of noise emission values are not within the scope of this standard. NOTE 101 For determining and verif

36、ying noise emission values declared in product specifications, see IEC 60704-3. 1.3 Measurement uncertainty Replacement: The estimated values of standard deviations of sound power levels determined according to this standard are indicated in Table 101: BS EN 60704-2-14:2013Copyright European Committ

47、 by tape. Doors or lids shall be closed. If available, adjustable feet shall be adjusted according to the manufacturers instructions to give minimum noise emission. 6.1.3 Replacement: Prior to noise measurements, the appliance, equipped as for intended use, shall have been in operation for the runni

48、ng-in for at least 16 h at an ambient temperature as specified in 6.3. During the running-in the thermostat adjustment has to be ascertained which establishes the test temperature as specified in 6.4.2. 6.1.4 Replacement: Immediately before each series of noise measurements, the appliance shall be operated until a steady state has been reached but at least for three complete running periods.
