This Euro
23、pean Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2014, and conflicting national standards shall be withdrawn at the latest by December 2014. Attention is drawn to the possibility that some of the e
24、lements 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 has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports
25、essential requirements of EU Directive 2009/142/EC. For relationship with EU Directive 2009/142/EC, see informative Annex ZA, which is an integral part of this document. This document is intended to be used in conjunction with EN 13611:2007+A2:2011. This document refers to clauses of EN 13611:2007+A

30、cope This European Standard specifies the safety, construction and performance requirements for combustion product sensing devices intended to be used in combustion control systems, hereinafter referred to as CPSD. This European Standard applies to sensing devices for the measurement of combustion p
31、roducts from burners and appliances for domestic, commercial and industrial use burning: gaseous fuels according to EN 437; or liquid fuels having a viscosity at the burner inlet of 1,6 mm2/s (cSt) up to 6 mm2/s (cSt) at 20 C, higher boiling petroleum based first raffinates (viscosity greater than 6
32、 mm2/s), that require preheating for proper atomisation. This European Standard applies to all types of stationary sensing devices measuring flue gas components O2, CO, CO2, H2, CxHy, NOX, SO2or for a combination of them (multiple gasses). This European Standard applies also to sensing devices for e
33、xtractive systems. This European Standard does not cover sensor requirements for combustible gas, combustible gas mixture and oil quality. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
