Die Annotation des Normtextes ČSN EN 17928-3 (386465):

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
