22、triction 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. DIN EN 1112:2008-06 EN 1112:2008 (E) 6 1 Scope T

23、his 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 hand showers of any material used for ablut

24、ionary 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 incorporated in tapware (e.g. sink and wash

25、 basin mixing valves) are not covered by this standard. Details of pressures and temperatures are given in Table 1.

26、 (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 (normal) jets need not have this facility. 14 R

27、otary 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 connection shall be capable of functioni

28、ng correctly and shall prevent twisting of the shower hose. DIN EN 1112:2008-06 EN 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 maintaining the appropriate test pr

29、essure 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 rotate the shower handset relative to

30、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 specified in Table 7. Table 7 Pressure
