The responsible

5、 German body involved in its preparation was the Normenausschuss Materialprfung (Materials Testing Standards Committee), Technical Committee NA 062-02-32 AA Bauakustische Instal-lationsmessungen. In addition to the legal units of measurement, this standard also uses the unit “inch”. It is important

6、to note that according to the German law on units in metrology, the use of the unit “mmHg” is not permitted in official or business communications within Germany. Amendment 1:2008 has been integrated in this standard and is marked by a vertical line in the left margin. The DIN Standards correspondin

30、tions may lead to annoyance in adjacent rooms, for example in dwellings,hospitals and hotels, especially at night. This noise has its origin mainly in appliances. Standardisedmeasurements of such noise are needed to permit comparison of the noise of commercial products made indifferent countries.Thi

31、s part of EN ISO 3822 describes a method of measurement allowing comparable results to be obtained inlaboratory 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

32、noise standard is utilised. This procedure can beregarded as a kind of calibration of the test arrangement. The installation noise standard is described in detail andthe basic arrangements for a laboratory water supply installation are given in this part of EN ISO 3822.The test conditions described

33、herein constitute the standard reference conditions essential for comparisonsbetween laboratories.Descriptions of the mounting and operating conditions for testing different types of appliances are given in otherparts of this European Standard : see EN ISO 3822-2 for draw-off taps and mixing valves,

34、 EN ISO 3822-3 for in-line valves and EN ISO 3822-4 for special appliances.4 EN ISO 3822-1:1999+A1:2008 (E) DIN EN ISO 3822-1:2009-07 1 ScopeThis part of EN ISO 3822 specifies a method of measurement, in the laboratory, of the noise emission resultingfrom the flow of water through appliances and equ

35、ipment used in water supply installations.The items covered include draw-off taps, in-line valves and special appliances, for example pressure reducers andwater-heating appliances, all of which are hereafter referred to as “appliances“.The method specified makes it possible to obtain comparable resu
