Gas infrastructure - Quality of gas - Group H

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.

Gasinfrastruktur - Beschaffenheit von Gas - Gruppe H

Diese Europäische Norm legt die Kenngrößen und Parameter, sowie die zugehörigen Grenzwerte für die Beschaffenheit von als Gruppe H eingeteilten Gasen fest, die zu transportieren, in Speicher ein  und aus Speichern auszuspeisen, zu verteilen und zu verbrauchen sind.
ANMERKUNG   Für Informationen zu Gasfamilien und Gasgruppen, siehe EN 437.
Diese Norm umfasst keine Gase, die in isolierten Netzen befördert werden.
Für Biomethan gelten die zusätzlichen Anforderungen nach prEN 16723 1.

Infrastructures gazières - Qualité du gaz - Groupe H

La présente Norme européenne spécifie les caractéristiques et les paramètres de qualité des gaz ainsi que leurs limites, pour des gaz classés dans le groupe H qui sont destinés à être transportés, injectés dans et depuis les stockages, distribués et utilisés.
NOTE   Pour toute information sur les familles de gaz et groupes de gaz, voir l'EN 437.
La présente norme ne couvre pas les gaz transportés par des réseaux isolés.
Pour le biométhane, les exigences complémentaires indiquées dans l’EN 16723-1 s’appliquent.

Infrastruktura za plin - Kakovost plina - Skupina H

Ta osnutek evropskega standarda določa lastnosti in zahteve za pline, ki vstopajo v omrežja za prenos plinov skupine H druge družine, kot so opredeljeni v standardu EN 437, in je namenjen uporabi na mejnih točkah ter sčasoma tudi za omrežja in infrastrukturo za prenos takih plinov. Posebne zahteve za biometan niso vključene, ker so podane v standardu prEN ... (CEN/TC 408) OPOMBA:  Znano je, da lahko nekatere specifikacije nekaterim deležnikom povzročijo tehnične ali operativne težave, čeprav so v splošnem sprejemljive.  Taki vplivi so opredeljeni v standardu in zainteresirane stranke naj bi se skladno z zakonodajnimi organi dogovorile, kako zmanjšati njihov obseg.
