EN 16726:2015+A1:2018

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 Europäische Norm umfasst keine Gase, die in isolierten Netzen befördert werden.
Für Biomethan gelten die zusätzlichen Anforderungen nach EN 16723 1.

Infrastructures gazières - Qualité du gaz - Groupe H

Infrastruktura za plin - Kakovost plina - Skupina H (vključno z dopolnilom A1)

Ta evropski standard določa kakovostne karakteristike, parametre in njihove omejitve za pline iz skupine H, namenjene za prenos, vnos v vsebnike in odstranitev iz njih, distribucijo ter uporabo.
OPOMBA: Za več informacij o družinah in skupinah plinov glej standard EN 437.
Ta evropski standard ne zajema plinov, ki se prenašajo v izoliranih omrežjih.
Za biometan veljajo dodatne zahteve iz standarda prEN 16723 1.
