Cryogenic vessels - Large transportable vacuum-insulated vessels - Part 2: Operational requirements (ISO 20421-2:2017)

ISO 20421-2:2017 specifies operational requirements for large transportable vacuum-insulated cryogenic vessels.
These operational requirements include putting into service, filling, withdrawal, transport within the location, storage, maintenance, periodic inspection and emergency procedures.
For the transport of these vessels by public road, rail, waterway, sea and air, additional requirements can apply; these are defined in specific regulations.

Récipients cryogéniques - Grands récipients transportables, isolés, sous vide - Partie 2: Exigences de fonctionnement (ISO 20421-2:2017)

ISO 20421-2:2017 spécifie les exigences de fonctionnement relatives aux grands récipients cryogéniques transportables isolés sous vide.
Ces exigences de fonctionnement concernent la mise en service, le remplissage, le soutirage, le transport à l'intérieur du site, le stockage, la maintenance, les contrôles périodiques et les procédures d'urgence.
Pour le transport de ces récipients par route, rail, voie navigable, mer ou air, des exigences supplémentaires peuvent s'appliquer; celles-ci sont définies dans des réglementations spécifiques.

Kriogene posode - Velike premične, vakuumsko izolirane posode - 2. del: Zahteve za obratovanje (ISO 20421-2:2017)

Ta evropski standard se uporablja za delovne zahteve za velike premične vakuumsko izolirane kriogene posode s prostornino, večjo od 1000 litrov. Na področje uporabe standarda spada zagon, polnjenje, odstranitev iz uporabe, transport znotraj lokacije, vzdrževanje, redni pregledi in postopki ravnanja v sili. Zahteve za obratovanje za uporabo teh posod na javnih cestah, železnici, na morju in v zraku niso zajete v tem standardu. Za transport teh posod po javni cesti, železnici, morju in zraku se uporabljajo druge zahteve, ki so določene v posebnih predpisih. Standard se uporablja za posode za kriogene tekočine, kot je določeno v dokumentu WI 004.
