Introduction
The European Commission in its standardization requests M/533 of March 12th, 2015 and M/581 of
th
March 24 , 2022, 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 the 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 Directive 2014/94/EU and the future EU Regulation
repealing the Directive 2014/94/EU (AFIR) and M/533 and M/581, European Standards specifying only
the required specifications for ensuring the interoperability of refuelling points should be provided.
European standards and common requirements with respect to “interoperability” mean the capability of
an infrastructure to supply energy (in this document, hydrogen) 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.
This document also addresses the standardization request M/581 for a European standard supporting
an interoperable infrastructure for hydrogen supply for road transport and containing technical
specifications with a unified solution for hydrogen refuelling points dispensing compressed (gaseous)
hydrogen for heavy duty vehicles.
1 Scope
This document defines the minimum requirements to ensure the interoperability of hydrogen refuelling
points, including refuelling protocols that dispense gaseous hydrogen to road vehicles (e.g. Fuel Cell

accordance with existing relevant European and national legislation, are not included in this document.
This document applies to hydrogen refuelling points dispensing gaseous hydrogen to vehicles compliant
