Standards Development

Scope

This European Standard describes specific functional requirements for the renovation of pipework in existing gas infrastructures. This European Standard is intended to be applied with the requirements of EN 12007-1.

This European Standard does not apply to pipework in above ground installations. This European Standard covers the various renovation technologies for gas piping in the range of sizes covering gas mains and gas service lines and is intended to be applied in association with EN 12007-1. Certain pipe networks originally for other purposes can be considered for renovation technologies to make them suitable for gas infrastructure. This European Standard specifies common basic principles for gas infrastructure. Users of this European Standard are expected to be aware that more detailed national standards and/or code of practice can exist in the CEN member countries. This European Standard is intended to be applied in association with these national standards and/or codes of practice setting out the above-mentioned basic principles.

Purpose

This proposal intends

- to generally revise the technical provisions for pipelines with maximum operation pressure up to and including 16 bar for the state of the art

 - to support the decarbonisation of the energy grid and the establishment of the future hydrogen grid by providing the appropriate technical provisions for the topic

 - to ensure safety over the different stages of life-cycle of the hydrogen grid.

- to adapt the document to climate requirements in line with EC policy for adaptation to climate change
