29、ing ranges, ovens, grills, microwave ovens and any combination of these for household and similar use. NOTE 101 These particular requirements do not apply to hobs due to lack of standardised load (pans) representative of normal use and ensuring a good repeatability of tests. For these applications,

30、the loading and operating conditions are under consideration. This standard does not apply to appliances or parts of appliances that use gas energy. 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 electric cook

31、ing ranges, ovens, grills, microwave ovens and any combination of these. 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 appliance under test

32、fulfils the requirements specified in 1.3 of ISO 3743-1:1994 and ISO 3743-2:1994. 1.2 Object Addition: The methods described 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 det
