34、ation. 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 cooking ranges, ovens, grills, microwave ovens and any comb

35、ination 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 fulfils the requirements specified in 1.3 of ISO 3743-1

36、:1994 and ISO 3743-2:1994. 1.2 Object Addition: The methods described are specified for appliances without an operator present.
