23、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 endorsement, at the latest by November 2010, and conflicting

24、 national standards shall be withdrawn at the latest by November 2010. 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 rights. This document s

25、upersedes EN 1106:2001. 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(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part

26、of this document. This document is intended to be used in conjunction with EN 13611:2007.

27、responding clause. This European Standard adds clauses or subclauses to the structure of EN 13611:2007 which are particular to this standard. It should be noted that these clauses and subclauses are not indicated as an addition. It should be noted that the following significant technical changes com

28、pared to the previous edition have been incorporated in this European Standard: a) scope is enlarged to maximum inlet pressures up to and including 50 kPa (500 mbar); b) alignment with EN 13611:2007; c) updating of Clause 2, Normative references; d) requirements from EN 126:2004 relating to “Open an

29、d closed position of a tap“, “Compensation means for taps“ and “Spring effect in taps“ were included (refer to 6.101.9 to 6.101.11); e) requirements and tests relating to durability of elastomers in contact with gas (7.8 of this standard) are now totally aligned with EN 13611:2007, 7.8.
