This document specifies the functional requirements relevant for design, materials, construction, testing, operation and maintenance of gas pressure control stations to ensure their reliability in terms of safety of the station itself and the downstream system and continuity of service.
This document is applicable for gas pressure control stations which are part of gas transmission or distribution systems for hydrogen, and hydrogen rich, and methane rich gases. Additional requirements in the case of gases heavier than air and/or toxic or corrosive gases are not covered by this document.
This document does not apply to gas pressure control stations in operation prior to the publication of this document. However, Annex D of this document can be used as guidance for the evaluation of stations in operation prior to the publication of this document, regarding the change of the type of gas, e.g. repurposing for the use with hydrogen.
The stations covered by this document have a maximum upstream operating pressure, which does not exceed 100 bar. For higher maximum upstream operating pressures, this document can be used as a guideline.
If the inlet pipework of the station is a service line and the maximum upstream operating pressure does not exceed 16 bar and the design flow rate is equal to 2000 kW based on the gross calorific value or less, EN 12279 applies.
This document contains the basic system requirements for gas pressure control stations. Requirements for individual components (valves, regulators, safety devices, pipes, etc.) or installation of the components are contained in the appropriate European Standards.
NOTE   For combined control and measuring stations, the additional requirements of EN 1776 can apply.
The requirements in this document do not apply to the design and construction of auxiliary facilities such as sampling, calorimetering, odorization systems and density measuring. These facilities are covered by the appropriate European Standards, where existing, or applicable national standards.
The requirements of this document are based on good gas engineering practice under conditions normally encountered in the gas industry. Requirements for unusual conditions cannot be specifically provided for, nor are all engineering and construction details prescribed.
The objective of this document is to ensure the safe operation of such stations. This does not, however, relieve all concerned of the responsibility for taking the necessary care and applying effective quality and safety management during the design, construction, operation and maintenance.

This document establishes specific functional requirements of stations for the injection of hydrogen into transmission and distribution systems for fuel gases (natural gas, biomethane, SNG, hydrogen, fuel gas mixtures, etc.; see Figure 1) in accordance with European technical rules that ensure the interoperability of systems in addition to the general functional requirements of EN 17928 1:2024.
This document complements EN 17928 1:2024 by specifying the technical safety requirements to be observed with respect to the chemical and physical properties of hydrogen.
It furthermore complements the requirements on pipelines specified in EN 12007 3 and EN 1594 by describing the specific requirements with respect to hydrogen.
Additionally, it explains how to handle hydrogen measurements during the course of injection.
Dedicated requirements for the technical equipment of the gas transmission and distribution network for mixing hydrogen as an additive gas into the gas flow after the injection station are not covered by this document. However, requirements for the resulting gas mixture and the related coordination and interfaces between station and network operation are specified in this document.
This document represents the recommendations at the time of its preparation. This document does not apply to injection stations operating prior to the publication of this document.
This document specifies common basic principles for gas infrastructure. Users of this document are expected to be aware that more detailed national standards and/or codes of practice can exist in the CEN member countries. This document is intended to be applied in association with these national standards and/or codes of practice setting out the above-mentioned basic principles.
In the event of terms of additional requirements in national legislation/regulation than in this document, CEN/TR 13737 (all parts) illustrates these terms.
CEN/TR 13737 (all parts) gives:
—   legislation/regulations applicable in a member state;
—   if appropriate, more restrictive national requirements;
—   a national contact point for the latest information.

This document establishes the functional requirements for stations for the injection of biomethane, substitute natural gas (SNG) and hydrogen into gas transmission and distribution systems operated with gases (natural gas, biomethane, SNG, hydrogen, gas mixtures) in accordance with European technical rules that ensure the interoperability of systems.
Figure 1 describes the general approach including all the relevant functions that can be installed in different configurations. The injection of Hydrogen is covered separately in EN 17928-3:2024.
This document also applies to refeeding stations that feed such gases back into upstream gas supply networks; see Figure 2.
This document represents the state of the art at the time of its preparation.
