34、iat 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of an identical text or by endorsement, at the latest by February 2018, and conflicting national standards shall be withdrawn at the latest by February 2018. Attention is dra

35、wn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1111:1998. The main technical changes compared to the previous version are the following:

36、 a) the introduction of Clause 10 on backflow protection; b) the introduction of Clause 11 on test sequence; c) the introduction of Clause 13 on performance; d) the update of chapters on pressure resistance, torsional resistance and mechanical resistance; e) new Annexes A, B, C and D. According to t

37、he CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece,

BS EN 1111:2017EN 1111:2017 (E) 7 Introduction In respect of potential adverse effects on the

39、 quality of water intended for human consumption, caused by the product covered by this standard, the following should be noted: this standard provides no information as to whether the product can be used without restriction in any of the Member state of the EU or EFTA; it should be noted that, whil

40、e awaiting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of this product remain in force. BS EN 1111:2017EN 1111:2017 (E) 8 1 Scope This European Standard specifies general construction, performance and material requirements

41、 for PN 10 thermostatic mixing valves (TMV) and includes test methods for the verification of mixed water temperature performance at the point of use below 45 C. This does not exclude the selection of higher temperatures where available. When these devices are used to provide anti-scald protection f

42、or children, elderly and disabled persons the mixed water temperature needs to be set at a suitable bathing temperature (body temperature approximately 38 C) as children are at risk to scalding at lower temperatures than adults. This does not obviate the need for supervision of young children during

43、 bathing. It applies to valves intended for use on sanitary appliances in kitchens, washrooms (incl. all rooms with sanitary tapware, e.g. toilets and cloakrooms) and bath rooms operating under the conditions specified in Table 1. This standard allows TMVs to supply a single outlet or a small number

44、 of outlets in a “domestic” application (e.g. one valve controlling a shower, bath, basin and/or bidet), excluding valves specifically designed for supplying a large number of outlets (i.e. for institutional use). The tests described are type tests (laboratory tests) and not quality control tests ca
