25、Uncontrolled Copy, (c) BSIEN 60704-2-5:2005 4 INTRODUCTION The measuring conditions specified in this Part 2-5 provide for sufficient accuracy in determining the levels of noise emitted and comparing the results of measurements taken by different laboratories, whilst simulating as far as possible th

26、e practical use of electric thermal storage room heaters. It is recommended to consider the determination of noise levels as part of a comprehensive testing procedure covering many aspects of the properties and performance of electric thermal storage room heaters. NOTE 1 As stated in the introductio

27、n to Part 1, this test code is concerned with airborne noise only. NOTE 2 The noise measurements are carried out without heating for three main reasons: the origin of noise is the fan; the heating takes a very long time; the overheating of the room and the measurement equipment.

29、 Part 1 is applicable except as follows: 1.1 Scope 1.1.1 General Replacement: These particular requirements apply to the electric thermal storage room heaters having forced convection output, designed for placing on the floor, for wall-mounting or for building-in. These particular requirements do no

30、t apply to: controlled output thermal storage heaters with natural convection; free output thermal storage heaters; permanently installed central storage heating systems or their parts. 1.1.2 Types of noise Replacement: ISO 3743-1, ISO 3743-2 and ISO 3744 can all be used for measuring noise emitted

31、by electric thermal storage room heaters. 1.1.3 Size of the source Replacement: The method specified 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 applian

32、ce under test fulfils the requirements specified in 1.3 of ISO 3743-1 and ISO 3743-2. 1.2 Object Addition: The frequency range of interest, for sound power determination on electric thermal storage room heaters, includes at least the octave bands with centre frequencies from 63 Hz to 8 000 Hz. NOTE

33、101 In many cases, the 63 Hz octave band level does not participate significantly to the A-weighted level.

34、e room effect. Requirements for the declaration of noise emission values are not within the scope of this standard. NOTE 103 For determining and verifying noise emission values, declared in product specifications, see IEC 60704-3. 1.3 Measurement uncertainty Replacement: The estimated values of stan

35、dard deviations of sound power levels, determined according to this standard, are: Standard deviation (dB) r (repeatability) R (reproducibility) 0,4 1,0 Addition: 1.101 Standard deviation for declaration and verification For the purpose of determining and verifying declared noise emission values, ac
