This Technical Report contains, for each country affected, a national page where the relevant national legislation/regulations for the field of gas infrastructure are listed. The national page can further contain the relevant national standards and/or codes of practice and national bodies which can act as further sources of information, if an interested party needs further guidance.

The national page can, if necessary, indicate any requirements in the national legislation/regulations that are more stringent than those in the European Standards prepared by CEN/TC 234 . This is done however without giving any details.

This does not apply to requirements contained in clauses that are harmonized to any new approach directive.

This Technical Report is intended to be a guideline for the national implementation of the functional European Standards elaborated by CEN/TC 234 "Gas infrastructure".
