Cryogenic vessels - Cleanliness for cryogenic service (ISO 23208:2017)

ISO 23208:2017 specifies the minimum requirements for the cleanliness of all surfaces of cryogenic vessels and associated accessories that are in contact with the cryogenic fluid at any expected operating conditions.
ISO 23208:2017 defines the acceptable level of surface and particle contamination to minimize the risk of malfunction of equipment and ensure safety against ignition when in contact with oxygen or oxidizing fluids (see ISO 10156).

Kryo-Behälter - Reinheit für den tiefkalten Betrieb (ISO 23208:2017)

Dieses Dokument legt die Mindestanforderungen an die Reinheit aller Oberflächen von Kryo-Behältern und der zugehörigen Zubehörteilen fest, die mit dem tiefkalten Fluid bei allen zu erwartenden Betriebsbedingungen in Berührung kommen.
Dieses Dokument legt den annehmbaren Grad von Oberflächenverunreinigungen und Verunreinigungen durch Partikel fest, um das Risiko des Versagens der Einrichtung zu minimieren und Schutz gegen das Entzünden bei Berührung mit Sauerstoff oder oxidierenden Fluiden zu bieten (siehe ISO 10156).

Récipients cryogéniques - Propreté en service cryogénique (ISO 23208:2017)

Le présent document spécifie les exigences minimales de propreté applicables à toutes les surfaces des récipients cryogéniques et de leurs accessoires, qui se trouvent en contact avec le fluide cryogénique, quelles que soient les conditions d'utilisation prévues.
Le présent document définit le niveau acceptable de contamination des surfaces et des particules, afin de minimiser les risques de dysfonctionnements de l'équipement et d'assurer une protection contre les risques d'ignition lors de l'entrée en contact avec l'oxygène ou les fluides oxydants (voir l'ISO 10156).

Kriogene posode - Čistoča za obratovanje v kriogenem območju (ISO 23208:2017)

Ta dokument določa minimalne zahteve za čistočo vseh površin kriogenskih posod in povezanega pribora, ki so v stiku s kriogeno tekočino pri vseh pričakovanih obratovalnih pogojih.
Ta dokument opredeljuje mejo sprejemljivosti površinskega onesnaženja in onesnaženja z delci za zmanjšanje tveganja za motnje v delovanju opreme in zagotovitev zaščite pred vžigom ob stiku s kisikom ali tekočinami, ki oksidirajo (glej EN ISO 10156).
