Over deze norm
This European Standard specifies the safety, construction and performance requirements for automatic shutoff valves for use with gas burners, gas appliances and similar use, hereafter referred to as ‘valves’. This European Standard is applicable to valves with declared maximum inlet pressures up to and including 500 kPa (5 bar) of nominal connection sizes up to and including DN 250 for use with one or more fuel gases in accordance with EN 437. This European Standard is applicable to electrically operated valves and to valves actuated by fluids where the control valves for these fluids are actuated electrically, but not to any external electrical devices for switching the control signal or actuating energy. An assessment method for valve designs is given by this European Standard. This European Standard is also applicable to valves where the flow rate is controlled by external electrical signals, either in discrete steps or proportional to the applied signal. This European Standard is also applicable to valves fitted with closed position indicator switches. This document is intended to be used in conjunction with EN 13611:2007. This document refers to clauses of EN 13611:2007 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 which are particular to this European Standard i.e. sub-clauses or annexes, which are additional to those in EN 13611:2007, 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. 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; b) normative references: ISO 4400 and ISO 6952 are changed to EN 175301-803; c) terms and definitions are aligned to EN 13611:2007; d) sub-clause 6.101 has been moved to sub-clause 8.11.102; e) installation and operating instructions are integrated in one sub-clause; f) changes in Annex ZA regarding 1.2, 1.2.2, 1.2.3, 1.3, 3.1.1, 3.3, 3.6, 3.7, 3.8, 3.11, 3.12, 3.2.1 and in addition Annex II and III were deleted. 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.
