Gas Quality
General Information
Frequently Asked Questions
CEN/TC 234/WG 11 is a Working Group within the European Committee for Standardization (CEN). It is named "Gas Quality". This committee has published 4 standards.
CEN/TC 234/WG 11 develops CEN standards in the area of Information technology. Currently, there are 4 published standards from this working group.
The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.
A Working Group in CEN is a specialized group responsible for developing standards or technical work within a defined scope. These bodies bring together international experts to create consensus-based standards that support global trade, safety, and interoperability.
This European standard specifies gas quality characteristics, parameters and their limits, for gases classified as group H that are to be transmitted, injected into and from storages, distributed and utilized.
NOTE For information on gas families and gas groups see EN 437.
This European standard does not cover gases conveyed on isolated networks.
For biomethane, additional requirements indicated in prEN 16723 1 apply.

This document defines the quality of gaseous hydrogen, i.e. its parameters and limiting values, to be transmitted, injected into and extracted from storages, distributed and utilized in fully and/or partially rededicated gas infrastructure and connected applications in a safe way.
This document gives evidence to the end-user which minimum exit hydrogen quality can be expected and ensured from natural gas infrastructure as minimum requirement and without further purification.
NOTE 1 The rededicated gas infrastructure can include new parts of this infrastructure constructed/added after the conversion of the natural gas grid.
NOTE 2 It is expected that over time the hydrogen delivered through such pipework will improve in quality, e.g. due to the increase in share of high purity hydrogen produced by electrolysis This will be taken into account in further development of this document.
