DIN CEN/TR 13737-1*DIN SPEC 30611:2012-11

This part of the Technical Report contains the definition of 'Functional Standardisation' in the context of CEN/TC 234 and explains their relationship with relevant European Directives, national legislation and national standards. It is intended as a guideline for the national implementation of the functional European Standards elaborated by CEN/TC 234 'Gas infrastructure'. In its functional standards CEN/TC 234 establishes common safety principles to design, construct, operate and maintain safe and reliable gas infrastructure systems. The detail to comply with these principles is left to recognised national documents in support of national legislation. In the event of conflicts in terms of more restrictive requirements in the national legislation/regulation with the requirements of CEN/TC 234 standards the national legislation/regulation take precedence as illustrated in part 2 of this CEN Technical Report.
