Foreword
This document (EN 14382:2005/prA1:2008) 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 document is currently submitted to the Unique Acceptance Procedure.
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(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document.
This document specifies the additions and changes to EN 14382:2005 concerning mainly the extension of
harmonized part to differential strength safety devices and to various combinations including a pressure regulator
and a safety device and the extension of the non-applicability to the safety shut off devices incorporated into
pressure-regulating device used in service lines. Further the Clause 3 dealing with terms, symbols and definitions
has been partially re-organized.
