functional classes:
-   class A: SSDs that close when damage to the pressure sensing element occurs (applicable to overpressure SSDs only) or when external power fails;
-   class B: SSDs that do not close when damage to the pressure sensing element occurs or are able to be opened automatically by the pressure control system (applicable to overpressure SSDs only).
SSDs complying with the requirements of this document may be declared as "in conformity with EN 14382" and bear the mark "EN 14382".
The material and functional requirements specified in this document may be applied to SSDs which use thermal energy or the effects of electrical energy to trip the operation of the closing member. For these SSDs the operational parameters are n

EN 14382:2005 (E) 5 Foreword This document (EN 14382:2005) has been prepared by Technical Committee CEN/TC 235 “Gas pressure regulators and associated safety devices for use in gas transmission and distribution”, the secretariat of which is held by UNI. 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of an identical text or by endorsement, at the latest by September 2005, and conflicting national standards shall be withdrawn at the latest by September 2005. This document supersedes EN 14382:2002. 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 97/23/EC. For relationship with EU Directive 97/23/EC, see informative Annex ZA, which is an integral part of this document. Safety shut-off devices dealt with in this document are standard safety shut-off devices and, when used in pressure regulating stations complying with EN 12186 or EN 12279, they are considered as standard pressure equipment in accordance with Clause 3.1 of Art. 1 of Pressure Equipment Directive (PED). For standard safety shut-off devices used in pressure regulating stations complying with EN 12186 or EN 12279, Table ZA.1 given in Annex ZA includes all applicable Essential Requirements given in Annex I of PED except the external resistance to environmental conditions where corrosion occurs. The normative Annex J of this document lists some suitable materials for pressure containing parts, inner metallic partition walls, fasteners and connectors. Other materials may be used when complying with the restrictions given in Table 5. A safety shut-off-device does not need protection against exceeding its allowable limit of pressure if the maximum downstream incidental pressure (MIPd) of the upstream gas pressure regulating station is less than or equal to 1,1 times the maximum allowable pressure (PS) of the safety shut-off device itself. The continuing integrity of safety shut-off devices is assured by periodic functional checks. For periodic functional checks it is common to refer to national regulations/standards where existing or users/manufacturers practices. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.



EN 14382:2005 (E) 6 1 Scope This document specifies constructional, functional, sizing, and testing requirements, also documentation and marking of gas safety shut-off devices used in the pressure regulating stations in accordance with EN 12186 or EN 12279:  for inlet pressures up to 100 bar and nominal diameters up to DN 400;  for an operating temperature range from –20 °C to +60 °C, which operate with fuel gases of the 1st and 2nd family in accordance with EN 437 in transmission and distribution networks and also in commercial and industrial installations. "Gas safety shut-off devices" will hereafter be called "SSDs" except in titles. The harmonized part of this document deals with standard safety shut-off devices used in pressure regulating stations complying with EN 12186 or EN 12279. For standard safety shut-off devices integral strength type when used in pressure regulating stations complying with EN 12186 or EN 12279, Annex ZA lists all applicable Essential Requirements except the external resistance to environmental conditions where corrosion occurs. This document considers the following classes of SSDs: temperature classes:  class 1: operating temperature range from –10 °C to 60 °C;  class 2: operating temperature range from –20 °C to 60 °C; functional classes:  class A: SSDs that close when damage to the pressure sensing element occurs (applicable to overpressure SSDs only) or when external power fails;  class B: SSDs that do not close when damage to the pressure sensing element occurs or are able to be opened automatically by the pressure control system (applicable to overpressure SSDs only). SSDs complying with the requirements of this document may be declared as “in conformity with EN 14382“ and bear the mark “EN 14382”. The material and functional requirements specified in this document may be applied to SSDs which use thermal energy or the effects of electrical energy to trip the operation of the closing member. For these SSDs the operational parameters are not specified in this document. This document does not apply to:  SSDs upstream from/on/in domestic gas-consuming appliances which are installed downstream of domestic gas meters;  SSDs in accordance with prEN xxxxxx (WI 00235003 under preparation by CEN/TC 235).
