28、ecially at night. This noise has its origin mainly in appliances. Standardised measurements of such noise are needed to permit comparison of the noise of commercial products made in different countries. This part of EN ISO 3822 describes a method of measurement allowing comparable results to be obta
29、ined in laboratory measurements. It is not possible to describe in detail how a given tap would give the same result in different laboratories. Therefore, the principle of comparing results to an installation noise standard is utilised. This procedure can be regarded as a kind of calibration of the
30、test arrangement. The installation noise standard is described in detail and the basic arrangements for a laboratory water supply installation are given in this part of EN ISO 3822. The test conditions described herein constitute the standard reference conditions essential for comparisons between la
31、boratories. Descriptions of the mounting and operating conditions for testing different types of appliances are given in other parts of this European Standard: see EN ISO 3822-2 for draw-off taps and mixing valves, EN ISO 3822-3 for in-line valves and EN ISO 3822-4 for special appliances. 1 Scope Th
32、is part of EN ISO 3822 specifies a method of measurement, in the laboratory, of the noise emission resulting from the flow of water through appliances and equipment used in water supply installations. The items covered include draw-off taps, in-line valves and special appliances, for example pressur
33、e reducers and water-heating appliances, all of which are hereafter referred to as “appliances”. The method specified makes it possible to obtain comparable results of measurements in different laboratories. 2 Normative references This European Standard incorporates by dated or undated reference, pr

In this part of EN ISO 3822 octave band sound press
40、ure levels and sound pressure level differences are denoted by the subscript n 3.2 a-weighted sound pressure level, in decibels the sound pressure level weighted with the A-weighting specified in EN 60651 3.3 appliance sound pressure level, Lapn for octave bands a quantity defined by: 3.4 appliance
41、sound pressure level, Lap in decibels the A-weighted sound pressure level, which is a characteristic value for the noise emission by an appliance. It is defined, in decibels, by: When the sound pressure level difference (Lsn p Lsrn) at the octave band mid-frequencies from 125 Hz to 4 000 Hz is const
42、ant to within 2 dB (see clause 8), the appliance sound pressure level Lap may be obtained directly from the A-weighted sound pressure levels as follows: The appliance sound pressure level Lap shall always be given rounded to the nearest whole decibel. Lapn = Ln (Lsn Lsrn)(1) where Lnis the average o
43、ctave band sound pressure level in octave n, in the test room, due to the noise produced by the appliance under the specified test conditions; Lsnis the corresponding octave band sound pressure level in the test room due to the noise produced by the installation noise standard (abbreviation INS) at
44、a flow pressure of 0,3 Mpaa (see clause 7); Lsrnis the reference value of the octave band sound pressure level in the octave n for the INS at flow pressure of 0,3 MPa (see clause 7). a 1 MPa = 10 bar (2) where n = 1, 2, 3, ., 6 are the octaves with mid-frequencies from 125 Hz to 4 000 Hz; k(A)n are
45、the A-weighting values, in decibels, given in EN 60651 for the six octave mid-frequencies from 125 Hz to 4 000 Hz. Lap = L (Ls Lsr)(3) where Lis the average A-weighted sound pressure level in the test room due to the noise produced by the appliance under the specified test conditions; Lsis the avera
46、ge A-weighted sound pressure level in the test room due to the noise produced by the INS at a flow pressure of 0,3 MPa; Lsris the reference A-weighted sound pressure level of the INS at a flow pressure of 0,3 MPa (see clause 7).

47、00 2006, Uncontrolled Copy, (c) BSI EN ISO 3822-1:1999 BSI 03-20005 4 Principle The appliance to be tested is mounted at the end of a water pipe, the test pipe, which is fixed to the wall of a room. The wall is called the test wall, the room the test room (see Figure 1). The sound generated by the a
48、ppliance is transmitted from the test pipe to the test wall. The airborne sound which is radiated from the test wall into the test room is measured. In order to obtain comparable measurements in different laboratories, the noise produced by the appliance is compared with the noise produced by an ins
49、tallation noise standard. 5 Test arrangement (see Figure 1) 5.1 Test room The test room shall have a volume of at least 30 m3. For new laboratories a volume of approximately 50 m3 is recommended. Two opposite surfaces of the test room shall not be less than 2,3 m apart. In the test room, the reverberation time should be between 1 s and 5 s for the octave bands with mid-frequencies from 125 Hz to 2 000 Hz. The sound field in the test room should be as diffuse as possible. Figure 1 Example of
