European foreword
This document (EN 17127:2018) has been prepared by Technical Committee CEN/TC 268 “Cryogenic
vessels and specific hydrogen technologies applications”, the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by May 2019, and conflicting national standards shall be
withdrawn at the latest by May 2019.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document has been prepared under Mandate M/533 given to CEN by the European Commission and
the European Free Trade Association.
It applies to vehicles covered by GTR13.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands,

Introduction
The European Commission in its standardization request M/533 of March 12th, 2015, aims to ensure that
technical specifications for interoperability of refuelling points are specified in European Standards
compatible with the relevant International Standards. These specifications aim to meet the European
needs, be compatible and aligned as much as possible with relevant International Standards and as far as
possible with existing refuelling infrastructure already in place and leave room to accommodate the
adopted standard to local technical, analytical and regulatory needs. The requested European Standards
aim to be technologically and commercially neutral and based on the know-how currently in possession
of the EU industry and of the public sector on a fair, reasonable and non-discriminatory basis.
According to the legal requirements given in the Alternative Fuels Infrastructure Directive (AFID) and
M/533, European Standards specifying only the required specifications for ensuring the interoperability
of refuelling points have to be provided. European standards and common requirements with respect to
“interoperability” mean the capacity of an infrastructure to supply energy that is compatible with all
vehicle technologies and allows seamless EU-wide mobility and a clear definition of fuel pressure and
temperature levels and connector designs .
The European Standardization Organizations (ESOs) should adopt European Standards in accordance
with Article 10 of Regulation (EU) No 1025/2012 of the European Parliament and of the Council, and
those standards should be based on current International Standards or ongoing international
standardization work, where applicable.
Direction from the standardization request M/533 for European Standards for hydrogen supply are to
develop European Standards containing technical solutions for interoperability with technical specifications
in regard to Article 5 and point 2 of Annex II, in particular for:
a) outdoor hydrogen refuelling points dispensing gaseous hydrogen;
b) hydrogen purity dispensed by hydrogen refuelling points;
c) fuelling algorithms and equipment of hydrogen refuelling points;
d) connectors for vehicles for the refuelling of gaseous hydrogen.
This document specifies Items a) and c). Item b) is covered by EN 17124 and Item d) by EN ISO 17268.
The energy to be supplied is hydrogen as a fuel and this fuel is dispensed in a hydrogen refuelling station
meeting interoperability requirements.
