22、3822-3:2018ISO 3822-3:2018(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body intereste
23、d 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 ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Com
24、mission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents
25、should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for
26、 identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the co

30、pment used in water supply installations is specified in ISO 3822-1.This document gives detailed descriptions for mounting and operating in-line valves and appliances, which control the flow, pressure or temperature of the water in water supply installations in such laboratory tests.NOTE An in-line
31、valve is one through which water flows and which is permanently installed in a system of rigid pipework upstream of the outlet fitting.These in-line valves and appliances are for use with cold and/or hot water in buildings (stop valves, check valves, in-line thermostatic and mechanical mixing valves
32、, domestic water meters, valve combinations for installation in water heater feed pipes, pressure reducing valves, flow restrictors, water governors, service valves, in-line temperature and pressure relief valves, etc.).

34、ances which control the flow, pressure or temperature of the water in water supply installations, when measuring noise emission resulting from water flow.It is applicable to in-line valves and appliances of maximum nominal size DN 32 and to systems in which the maximum water flow rate does not excee
35、d 1,6 l/s.NOTE See ISO 6708; DN is the symbol for “nominal size”. The number of the nominal size is loosely related to the inside diameter (in millimetres) of the in-tine valves and appliances.The procedures described are for general use for all types of in-line valves of conventional design.2 Norma

40、line valves or appliance shall be installed in its normal working position, which is generally vertical or horizontal.The test shall be carried out for the noisier of the two positions, which shall be determined by a short preliminary test.If the manufacturer specifies that the appliance may be inst
41、alled in other positions, then the short preliminary test shall be carried out for these positions.4.1.3 ConnectionThe in-line valves or appliance shall be connected to the test pipe in accordance with the appropriate description in 4.3 to 4.7. The connection shall be made so that no air will be tra
42、pped therein.In-line valves or appliances fitted with connections not covered by 4.3 to 4.5 inclusive shall be connected to the test pipe and to the discharge system so as to provide a rigid and watertight connection in accordance with good practice and workmanship.4.2 Fitting to the test pipeThe te
43、st pipe shall end with a galvanised (hot-dip zinc coated) union, taper seat size 1, U11 complying with ISO 49.In-line valves and appliances, including connecting pipe (see 4.1) shall be connected to the union using if necessary a combination of galvanised (hot-dip zinc coated) fittings complying wit
