The work of preparing Internat
32、ional Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with I
33、SO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an In
34、ternational Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 3822-4 was prepared by the European Committee for Standardization (CEN) in collaboration with ISO Technical Committee TC 43, Acoustics, Subcommittee SC 2, Building acoustics, in ac
35、cordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). This second edition cancels and replaces the first edition (ISO 3822-4:1985), which has been technically revised. ISO 3822 consists of the following parts, under the general title Acoustics Laboratory tests
36、on noise emission from appliances and equipment used in water supply installations: Part 1: Method of measurement; Part 2: Mounting and operating conditions for draw-off taps and mixing valves; Part 3: Mounting and operating conditions for in-line valves and appliances; Part 4: Mounting and operatin
37、g conditions for special appliances. Annex A, Annex B, Annex C and Annex D form an integral part of this part of ISO 3822. Annex E is for information only.

38、roduction The method of measurement for laboratory tests on noise emission from appliances and equipment used in water supply installations is specified in EN ISO 3822-1. The mounting and operating conditions for draw-off taps and mixing valves are described in EN ISO 3822-2 whereas EN ISO 3822-3 de
39、scribes the mounting and operating conditions for in-line valves and appliances. This part of EN ISO 3822 describes the mounting and operating conditions for laboratory tests of appliances of such construction that they cannot easily be considered as draw-off or in-line appliances, e.g. water heater
40、s, shower heads, etc. 1 Scope This part of EN ISO 3822 specifies the mounting and operating conditions to be used for a number of appliances which cannot be regarded as draw-off or in-line valves, when measuring the noise emission resulting from water flow. 2 Normative references This European Stand

These normative references are cited at the appropriate places in the text and the publications are listed hereafter.

Special appliances, including connecting pipe, shall be co
47、nnected to the union using if necessary a combination of galvanised (hot-dip zinc coated) fittings complying with ISO 49. Changes in direction shall be accomplished by means of long sweep bends size 1 only. Reduction or enlargement of size shall only be made at the inlet connection of the appliance
48、or connecting pipe. The combination of fittings used shall result in the appliance being mounted in the normal position of use (see Figure 1). 3.2 Float-operated valves 3.2.1 General A float-operated valve not forming part of a particular flushing unit shall be tested in a standard test cistern for
49、which the internal dimensions are given in Table 1. Table 1 Internal dimensions of standard test cisterns Float-operated valves forming part of a flushing unit, e.g. a toilet flushing unit, shall be tested together with the cisterns in which they are mounted and also with the stop-valve if it forms part of the unit.
