Bibliography
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.NOTEFor 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.
