28、s, especially 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 b

29、e obtained 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 o

30、f the 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 betw

31、een laboratories. 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 Sc

32、ope This 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 p

33、ressure 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 referen

39、he following definitions apply: 3.1 octave band sound pressure level, in decibels the unweighted sound pressure level in the frequency band of one octave. In this part of EN ISO 3822 octave band sound pressure levels and sound pressure level differences are denoted by the subscript n 3.2 a-weighted

40、sound pressure level, in decibels the sound pressure level weighted with the A-weighting specified in EN 60651 3.3 appliance sound pressure level, L apnfor octave bands a quantity defined by: 3.4 appliance sound pressure level, L apin decibels the A-weighted sound pressure level, which is a characte

41、ristic value for the noise emission by an appliance. It is defined, in decibels, by: When the sound pressure level difference (L snp L srn ) at the octave band mid-frequencies from 125 Hz to 4 000 Hz is constant to within 2 d B ( s e e c l a u s e 8), the appliance sound pressure level L apmay be ob

42、tained directly from the A-weighted sound pressure levels as follows: The appliance sound pressure level L apshall always be given rounded to the nearest whole decibel. L apn= L n (L sn L srn ) (1) where L n is the average octave band sound pressure level in octave n, in the test room, due to the no

43、ise produced by the appliance under the specified test conditions; L sn is the corresponding octave band sound pressure level in the test room due to the noise produced by the installation noise standard (abbreviation INS) at a flow pressure of 0,3 Mpa a(see clause 7); L srn is the reference value o

44、f 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) nare the A-weighting values, in decibels, given in EN 60651 for the six octav

45、e mid-frequencies from 125 Hz to 4 000 Hz. L ap= L (L s L sr ) (3) where L is the average A-weighted sound pressure level in the test room due to the noise produced by the appliance under the specified test conditions; L s is the average A-weighted sound pressure level in the test room due to the no

46、ise produced by the INS at a flow pressure of 0,3 MPa; L sr is the reference A-weighted sound pressure level of the INS at a flow pressure of 0,3 MPa (see clause 7). BS E N IS O 3822-1:1999 + A 1 : 2 0 0 8 5 BSI 2009 4 Principle The appliance to be tested is mounted at the end of a water pipe, the t

47、est 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 appliance 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

48、 order to obtain comparable measurements in different laboratories, the noise produced by the appliance is compared with the noise produced by an installation noise standard. 5 Test arrangement (see Figure 1) 5.1 Test room The test room shall have a volume of at least 30 m 3 . For new laboratories a

49、 volume of approximately 50 m 3 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.
