25、o electric hand-held hairdryers for household and similar use supplied from mains, which operate with a flow of air. These particular requirements can also be applied to analogous electrically operated devices such as hairstyling appliances, which produce the airflow by a fan. Helmet-type hairdryers
26、 are excluded from this standard. This standard does not apply to hair care appliances with radiant heating. 1.1.2 Types of noise Replacement: ISO 3743-1, ISO 3743-2 and ISO 3744 can be used for measuring noise emitted by electric hairdryers. 1.1.3 Size of the source Replacement: The method specifie
27、d in ISO 3744 is applicable to noise sources of any size (limited only by available test environment). When applying ISO 3743-1 and ISO 3743-2, care should be taken that the maximum size of the electric hair care appliance under test fulfils the requirements specified in 1.3 of ISO 3743-1 and ISO 37
28、43-2. 1.2 Object Addition: Requirements for the declaration of noise emission values are not within the scope of this standard. NOTE For determining and verifying noise emission values declared in product specifications, see IEC 60704-3. Page5 EN6070429:2003 1.3 Measurement uncertainty Replacement:
29、The estimated values of standard deviations of sound power levels, determined according to this standard, are as follows: Standard deviation dB r (repeatability) R (reproducibility) 0,4 0,8 Addition: 1.101 Standard deviation for declaration and verification For the purpose of determining and verifyi
30、ng declared noise emission values, according to IEC 60704-3, the following values apply: Standard deviation dB P (production) t (total) M (reference) 0,5 1,3 0,9 1,5 1,5 2 Normative references This clause of Part 1 is applicable. 3 Terms and definitions This clause of Part 1 is applicable except as
