Brief description

This European Standard EN 17649:2022 has been prepared by Technical Committee CEN/TC 234 "Gas infrastructure", the secretariat of which is held by DIN. It supersedes EN 15399:2018 and EN 16348:2013. and provides guidance on the establishment, implementation and maintenance of a safety management system, all in order to provide an efficient gas transmission and distribution infrastructure for the safe transport of gas. This European Standard supports a system operator in the implementation of a management system following the Plan-Do-Check-Act (PDCA) methodology. It can be used in conjunction with ISO Management Systems and also in case of assessment or certification by a third party. New points for attention in this document are adaptations to climate change and the injection of hydrogen and other gases into natural gas networks. As gases other than natural gas will be more often injected into existing natural gas networks in the future, Management of Change has been introduced in this document to ensure that all relevant safety aspects are taken into account when this occurs.
