Cryogenic vessels - Pumps for cryogenic service (ISO 24490:2016)

ISO 24490:2016 specifies the minimum requirements for the design, manufacture and testing of pumps for cryogenic service.
ISO 24490:2016 is applicable to centrifugal pumps. However, it can be applied to other types of cryogenic pumps (e.g. reciprocating pumps), where applicable.
This International Standard also gives guidance on the design of installations (see Annex A).
It does not specify requirements for operation or maintenance.
NOTE          For cryogenic fluids, see ISO 21029‑1, ISO 20421‑1 and/or ISO 21009‑1.

Kryo-Behälter - Pumpen für den Kryo-Betrieb (ISO 24490:2016)

Diese Internationale Norm legt die Mindestanforderungen für die Auslegung, die Fertigung, und die Prüfung von Pumpen für den Kryo Betrieb fest.
Diese Internationale Norm gilt für Kreiselpumpen. Sie kann jedoch, sofern zutreffend, auch für andere Pumpenbauarten (z. B. Kolbenpumpen) angewendet werden.
Diese Internationale Norm enthält auch Anleitungen zur Auslegung von Anlagen (siehe Anhang A).
Sie legt keine Anforderungen an Betrieb oder Instandhaltung fest.

Récipients cryogéniques - Pompes pour service cryogénique (ISO 24490:2016)

ISO 24490:2016 spécifie les exigences minimales en matière de conception, de fabrication et d'essais des pompes pour service cryogénique.
ISO 24490:2016 s'applique aux pompes centrifuges. Le cas échéant, elle peut toutefois être appliquée à d'autres types de pompes cryogéniques (pompes à piston, par exemple).
La présente Norme internationale donne également des préconisations pour la conception des installations (voir l'Annexe A).
Elle ne spécifie aucune exigence relative au fonctionnement ou à la maintenance.
NOTE          Pour les fluides cryogéniques, voir l'ISO 21029‑1, l'ISO 20421‑1 et/ou l'ISO 21009‑1.

Kriogene posode - Črpalke za kriogeno področje (ISO 24490:2016)

Ta standard določa minimalne zahteve za načrtovanje, izdelavo in preskušanje črpalk za kriogeno področje (t.j. za delo s kriogenimi tekočinami pod –10 °C). Ta standard zajema centrifugalne črpalke. Načela iz tega standarda se lahko uporabijo za druge vrste črpalk (npr. batne črpalke). Ta standard podaja tudi smernice glede načrtovanja objektov (glej dodatek A). Standard ne določa zahtev za obratovanje ali vzdrževanje.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
