Područje primjene nacrta:

This document establishes specific functional requirements of stations for the injection of hydrogen fuel gas into transmission and distribution systems for fuel gases (natural gas, biomethane, SNG, hydrogen fuel gas, 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 prEN 17928-1.
This document complements prEN 17928-1 by specifying the technical safety requirements to be observed with respect to the chemical and physical properties of hydrogen fuel gas.
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.
Requirements for the technical equipment for mixing hydrogen as an additive gas into the gas flow of the gas transmission and distribution system are not covered by this document. However, requirements for the resulting gas mixture are specified in 5.2, which specifies requirements for the operation of the injection station.
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.
