17、word This document (EN 1112:2008) has been prepared by Technical Committee CEN/TC 164 “Water supply”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by Aug
18、ust 2008, and conflicting national standards shall be withdrawn at the latest by August 2008. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent
19、rights. This document supersedes EN 1112:1997 and EN 13904:2003 The scope is enlarged to include requirements for shower outlets used with water supply systems of type 1 and type 2. See Tables 1, 3, 4, 5 and 7. According to the CEN/CENELEC Internal Regulations, the national standards organizations o
20、f the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slo

BS EN 1112:2008EN 1112:2008 (E) 5 Introduction In respect of potential adverse effects on the quality of water intended for human consumption, caused by the product covered by this standard: this standard provides no information as
22、to whether the product may be used without restriction in any of the Member States of the EU or EFTA; it should be noted that while awaiting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of these products remain in force. BS
23、 EN 1112:2008EN 1112:2008 (E) 6 1 Scope This European Standard specifies: the dimensional, leaktightness, mechanical, hydraulic and acoustic characteristics with which shower outlets shall comply; the procedures for testing these characteristics. This European Standard applies to shower heads and ha
24、nd showers of any material used for ablutionary purposes and intended for equipping and supplementing sanitary tapware for baths and showers. This European Standard applies to shower heads and hand showers connected downstream of the obturator of the tapware. Integral and remote spray attachments in
25、corporated in tapware (e.g. sink and wash basin mixing valves) are not covered by this standard. Details of pressures and temperatures are given in Table 1. Table 1 Conditions of use/Classifications Operating range of shower outlets Flow rate classes Acoustics Marking Water Supply system Limits Reco
26、mmended See clause 12.0 See clause 6.0 ZZ (0,025 Q 30 13 Maintenance The spray plate for needle (normal) jets shall be removable by the use of simple tools, or by special tools supplied by the manufacturer for cleaning purposes. Shower outlets with an integrated cleaning device for the needle (norma
27、l) jets need not have this facility. 14 Rotary connection 14.1 General The test described is a type test (laboratory test) and not a quality control test carried out during manufacture. If a shower handset has a rotary connection permitting the handle to turn freely relative to the shower hose, this
28、 connection shall be capable of functioning correctly and shall prevent twisting of the shower hose. BS EN 1112:2008EN 1112:2008 (E) 21 14.2 Test method 14.2.1 Principle The test is intended to check the function of any rotary connection. 14.2.2 Apparatus Key 1. water supply capable of supplying and
29、 maintaining the appropriate test pressure specified in Table 7; 2. rigid supply pipe for holding the shower handset at the connection thread so that the shower hangs down vertically; 3. device which engages with the shower handset in order to enable measurement of the initial torque necessary to ro
30、tate the shower handset relative to the rotary connection. Figure 13 Rotary connection test apparatus 14.2.3 Procedure Seal the spray forming device so that it is watertight. Connect the rotary connection of the shower handset to the supply pipe. Apply cold water 30 C at the appropriate pressure spe
31、cified in Table 7. Table 7 Pressure conditions for rotary connection test Supply system Pressure Type 1 (0,3 0,02) MPa (3 0,2) bar Type 2 (0,1 0,01) MPa (1,0 0,1) bar Measure the torque necessary to initiate rotation of the shower handset relative to the rotary connection. 14.2.4 Requirements The in
32、itial torque shall not exceed 0,1 Nm.
