21、6-1:2006 (E) 5 Introduction Generally speaking, determining the airborne noise emissions is only part of a comprehensive testing programme which takes into account many different viewpoints relating to the characteristics and behaviour in using a heat generator. It is therefore important that the re
22、quirements for noise tests, such as the measuring equipment and the environment in which it is used should always be considered within the prescribed context. It is also important whatever the ultimate purpose may be, to lay down procedures within a defined degree of accuracy, so that the measuring
23、results obtained from various different laboratories can be compared with one another. These conditions have been taken into account as far as possible in preparing these test methods. All test procedures defined in EN ISO 3741, EN ISO 3743, EN ISO 3744, EN ISO 3746 and EN ISO 9614 are permissible m
24、ethods. It should be emphasised that these test methods only apply to airborne noise. In many cases, however, structure-borne noise, such as can be transmitted into a neighbouring room, can also be of significance. It is envisaged that airborne noise emissions through the flue gas path will be dealt
25、 with in a separate part of this standard. All the basic and noise measurement standards of accuracy categories 1 to 3 are permissible under this testing standard. Sound values declared by the manufacturer can be measured according to these three categories, but in any case, the used category has to
26、 be stated. This European Standard sets out various methods for testing to approximate the airborne noise emitted by heat generators into the room of installation. EN 15036-1:2006 (E) 6 1 Scope This European Standard specifies test methods for airborne noise emissions from heat generators in a test
27、laboratory or at the place of installation. The test methods described in this European Standard, however, may be used for measuring the airborne noise emissions of the appliances and functions listed below. This European Standard applies to following appliances regardless of their heat output and t
28、he fuel used: wall-mounted and floor-standing heating appliances; forced-draught burners; boilers/forced-draught burner units; boilers with freely allocated forced-draught burners; pellet burners. According to this European Standard the manufacturer is allowed to choose an appropriate category of te
29、sting for the measured appliance. This European Standard does not apply to: appliances used exclusively for heating drinking-water; function of heating drinking-water in so-called combined water-heaters; heat generators which work with air as the heat transfer medium; electrical heating appliances;
30、structure-borne noise; sound transmission along the flue gas path. 2 Normative references The following referenced documents are indispensable for the application of this document.

39、tal sound energy radiated by that source per second, expressed in Watts (W). The sound power W, is customarily related to a reference sound power W0and expressed as a sound power level LWin decibels (dB) according to equation (1): 010WWL logW= (1) where W0is the reference sound power level of 1 pW (
40、= 1012W). EN 15036-1:2006 (E) 8 The main criteria for determining the choice of sound power level for the purpose of labelling the noise emission are: a) sound power level shall provide an adequate description of the noise emission and is independent of environmental factors; b) it shall be possible
41、 to determine the sound power level to a defined degree of accuracy from relatively simple acoustic tests which can be carried out under a large number of defined acoustic conditions. These test methods describe the objective procedure for determining the sound power level of airborne noise, LW. The
42、 following sound power levels can be determined: A-weighted sound power level LWA; sound power level in octave bands, LWOct.Tests shall be carried out on a frequency band covering at least an octave band from 125 Hz to 4000 Hz; sound power level in third bands, LWThird. Tests shall be carried out on
43、 a frequency band covering at least third-octave bands from 100 Hz to 5000 Hz. For practical use, LWAtest-stand measurements are sufficient for calculating the A-weighted sound power level. 4.2 Test method 4.2.1 Measurement approach To determine sound power level, there are three basic procedures. T
44、hese are: Conversion of sound pressure level measured into a reverberant field to sound power level. This approach is described in EN ISO 3741 and EN ISO 3743-1 and EN ISO 3743-2. Conversion of sound pressure level measured into a free-field (or assimilated to a free-field) according to EN ISO 3744,
45、 EN ISO 3745 and EN ISO 3746. Conversion of intensity field emitted around the appliance to sound power level. This approach is described in EN ISO 9614-1, EN ISO 9614-2 and EN ISO 9614-3. 4.2.2 Uncertainty of test Within each measurement approach in 4.2.1, different methods are described by specifi
46、c standards in order to reach different levels of accuracy on the final results. These accuracy levels are the following (from the best to the worst accuracy): Category 1 describes the precision class; Category 2 describes the engineering class; Category 3 describes the survey class. NOTE 1 For inst
47、ance, using a free-field approach, the three relevant standards are EN ISO 3745 (Category 1), EN ISO 3744 (Category 2) and EN ISO 3746 (Category 3). If the experimental approach is similar (measure of average sound pressure level on a fictitious area including the appliance), test requirements are d
48、ifferent depending on the targeted level of accuracy (number of points, difference between background and appliance noise, test environment correction, etc.). EN 15036-1:2006 (E) 9 NOTE 2 Depending on the accuracy category, the available information is different. Survey methods do not provide spectr
49、al data. According to accuracy categories, standard deviations on A-weighted are provided in Table 1. Table 1 - Standard deviations on A-weighted overall sound power level according to accuracy categories of standards Precision class Engineering class Survey class Standard deviation RdB 1 1,5 4 These standard deviations relate to a relatively flat spectrum. In case of tonal noise, standard deviation of the survey method is increased by 1 dB. In the hypothesis of a
