This clause of Part 1 is applicable except as follows: 1.1 Scope 1.1.1 General Addition: These particular requirements apply to electric cooking 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, 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 cooking ranges, ovens, grills, microwave ovens and any combination of these. 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 appliance under test 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 determining and verifying 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 as follows: Table 101 - Standard deviations of sound power levels Standard deviation dB sr (repeatability) sR (reproducibility) 0,4 1,0 1.101 Standard deviation for declaration and verification For the purpose of determining and verifying declared noise emission values according to IEC 60704-3, the following values apply: Table 102 - Standard deviations for declaration and verification Standard deviation dB sP (production) st (total) sM (reference) 1,0 - 1,7 1,4 - 2,0 2,0
