Foreword This document (EN 161:2011+A3:2013) has 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of an identical text or by endorsement, at the latest by July 2013, and conflicting national standards shall be withdrawn at the latest by July 2013. 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 supersedes %EN 161:2011+A2:2012&. This document includes Amendment 2, approved by CEN on 2012-06-10 and Amendment 3 approved by CEN on 2012-11-10. The start and finish of text introduced or altered by amendment is indicated in the text by tags #$ and %&. This document is intended to be used in conjunction with #EN 13611:2007+A2:2011$. This document refers to clauses of #EN 13611:2007+A2:2011$ or adapts clauses by stating “with the following modification”, “with the following addition”, “is replaced by the following” or "is not applicable" in the corresponding clause. This European Standard adds clauses or sub-clauses to the structure of
#EN 13611:2007+A2:2011$ which are particular to this European Standard i.e. sub-clauses or annexes, which are additional to those in #EN 13611:2007+A2:2011$, are numbered starting from 101 or are designated as Annex AA, BB, CC etc. It should be noted that these clauses and sub-clauses are not indicated as an addition. %At the time of publication of Amendment 2, Amendment 1 was still at the draft stage. Therefore, there will be no Amendment 1 for this project. The present document incorporates the changes of the original Amendment 1 and Amendment 2.& It should be noted that the following significant editorial changes compared to the previous edition have been incorporated in this European Standard:
a) alignment to #EN 13611:2007+A2:2011$; b) normative references: ISO 4400 and ISO 6952 are changed to EN 175301-803; c) terms and definitions are aligned to #EN 13611:2007+A2:2011$; d) %sub-clause 6.2.105, Balanced valves, has been changed; e) sub-clause 6.2.107, Additional requirements for shut-off function, has been changed;& f) sub-clause 6.101 has been moved to sub-clause 8.11.102; g) %sub-clause 7.105.1, Sealing force requirements, has been changed;& h) installation and operating instructions are integrated in one sub-clause; SIST EN 161:2011+A3:2013
SIL classification according to EN 61508 cannot be claimed based upon compliance with this standard. Valves with SIL classification do not meet automatically the requirements of this standard. %Primarily in industrial applications it is common practice to rate the safety of a plant based on values describing the likelihood of a dangerous failure. These values are being used to determine Safety Integrity Levels or Performance Levels when the system is being assessed in its entirety. CEN/TC 58 standards for safety relevant controls do go beyond this approach, because for a certain life span for which the product is specified, designed and tested a dangerous failure is not allowed at all. Failure modes are described and assessed in greater detail. Measures to prevent dangerous situations occurring are defined. Field experience over many decades is reflected in the CEN/TC 58 standards. Requirements of these standards can be considered as proven in practice. The PL assessment in Annex AA is only applicable to automatic shut-off valves which are already certified to this European Standard. It cannot be presumed that any Safety Integrity Level or Performance Level assessment alone would imply that requirements of a CEN/TC 58 standard have been met.
To be able to provide parameters to allow for any formal Safety Integrity Level or Performance Level system assessment the Annexes AA and BB of this document define a methodology to derive the relevant parameters from the requirements of this standard.& 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, Czech 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 Kingdom.
