22、ts on the quality of water intended for human consumption, caused by the product covered by this European Standard. This European Standard provides no information as to whether the product can be used without restriction in any of the Member States of the EU or EFTA. It should be noted that, while a
23、waiting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of these products remain in force. This document identifies characteristics and technical requirements for single and combination taps. BS EN 200:2008EN 200:2008 (E) 7 1
24、Scope This European Standard specifies: a) the field of application for pillar taps, bib taps, single and multi-hole combination taps for use in: 1) a supply system of Type 1 (see Figure 1); 2) a supply system of Type 2 (see Figure 2); b) the dimensional, leaktightness, pressure resistance, hydrauli
25、c performance, mechanical strength, endurance and acoustic characteristics of nominal size and single taps and combination taps; c) test methods to verify the characteristics. The tests described in this European Standard are type tests (laboratory tests) and not quality control tests carried out du
26、ring manufacture. This European Standard applies to draw-off taps (single taps and combination taps) for use with sanitary appliances installed in rooms used for bodily hygiene (cloakrooms, bathrooms etc.) and in kitchens, i.e. for use with baths, wash basins, bidets, showers and sinks. Figure 1 sho

35、esponding requirements (see Table 8). 8.2 Test methods 8.2.1 Principle The principle of the test consists of checking under cold water pressure the leaktightness of: the obturator (see 8.3); the complete tap (see 8.4); the bath/shower diverter (either manual or with automatic return) (see 8.5, 8.6 a
36、nd 8.7). In the case of a diverter with automatic return being considered to provide backflow prevention, it shall comply with the requirements of EN 14506 8.2.2 Apparatus A hydraulic test circuit, capable of supplying the required pressures and of maintaining them throughout the duration of the tes
37、ts. A hydraulic test circuit, capable of supplying gradually the required static and dynamic pressures and of maintaining them throughout the duration of the test. 8.3 Leaktightness of the obturator and of the tap upstream of the obturator(s) with the obturator in the closed position 8.3.1 Procedure
