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).
