Brief description
DVGW Code of Practice G 265-3 applies to the planning, manufacture, construction, testing, commissioning and operation of systems for feeding hydrogen into networks for the pipeline-based supply of gas and hydrogen to the general public, which are operated with gases in accordance with DVGW Code of Practice G 260, including the necessary connections and auxiliary equipment. This DVGW Code of Practice supplements DVGW Code of Practice G 265-1 with the specific safety requirements for the systems referred to in paragraph 1, which must be observed with regard to the material properties of hydrogen and hydrogen-enriched gas. When applying DVGW Code of Practice G 462, G 463 and G 472 for pipes within the feed-in system and connecting pipes, it supplements hydrogen-specific requirements. When applying DVGW worksheets G 491 and G 492 to pressure control and measuring systems as part of the feed-in system, it also supplements the hydrogen-specific requirements. It also describes the metrological handling of hydrogen in the course of the feed-in.
