31、 been prepared by Technical Committee CEN/TC 58 “Safety and control devices for burners and appliances burning gaseous or liquid fuels”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by

32、endorsement, at the latest by September 2014, and conflicting national standards shall be withdrawn at the latest by March 2017. 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

33、identifying any or all such patent rights. This document supersedes EN 1643:2000. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive 2009/142/EC. For relationship with EU

34、 Directive, see informative Annex ZA, which is an integral part of this document. This document refers to clauses of EN 13611:2007+A2:2011 or adapts it by stating “with the following modification”, “with the following addition”, “is replaced by the following” or “is not applicable” in the correspond

35、ing clause. This document adds clauses or sub-clauses to the structure of EN 13611:2007+A2:2011 which are particular to this standard, i.e. sub-clauses or annexes which are additional to those in EN 13611 are numbered starting from 101 or are designated as Annex AA, BB, CC etc. It should be noted th

36、at these clauses and sub-clauses are not indicated as an addition. If by reference to EN 13611 the term “control” is given, this term should be read as valve-proving systems. Note that the following provides details of significant technical changes between this document and the previous edition: a)

37、Alignment with EN 13611:2007+A2:2011; b) Integration of the requirements from ISO 23551-4. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Cz

38、ech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingd

DIN EN 1643:2014-09 EN 1643:2014 (E) 6 1 Scope This European Standard specifies safety, constructional and performance requirements of valve-proving systems, hereafter referred to as VPS, intended for use with gas burners and gas-burning appliances. It also describes the test procedures for chec

40、king compliance with these requirements and provides information necessary for the purchaser and user. This European Standard applies to all types of VPS which are used for the automatic detection of leakage in a gas burner section having at least two valves designed in accordance with EN 161 and wh

41、ich give a signal if the leakage of one of the valves exceeds the detection limit. This European Standard applies to VPSs with a maximum working pressure up to and including 500 kPa for use in systems using fuel gases of the 1st, 2ndor 3rdfamilies. This European Standard does not apply to VPSs for u

42、se in explosive atmospheres. This European Standard is applicable to AC and DC supplied VPS (for VPS supplied by stand-alone battery system, battery systems for mobile applications or systems which are intended to be connected to DC supply networks VPS see Annex I). Provisions for production control

43、 are not part of this European Standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
