EN ISO 16903:2015

Petroleum and natural gas industries - Characteristics of LNG, influencing the design, and material selection (ISO 16903:2015)

ISO 16903:2015 gives guidance on the characteristics of liquefied natural gas (LNG) and the cryogenic materials used in the LNG industry. It also gives guidance on health and safety matters. It is intended to act as a reference document for the implementation of other standards in the liquefied natural gas field. It is intended as a reference for use by persons who design or operate LNG facilities.

Erdöl- und Erdgasindustrie - Eigenschaften von Flüssigerdgas mit Einfluss auf die Auslegung und die Materialauswahl (ISO 16903:2015)

Diese Internationale Norm informiert über die Eigenschaften von Flüssigerdgas (LNG) und in der LNG-Industrie verwendeten tieftemperaturfesten Werkstoffe. Außerdem enthält sie Leitlinien zu Fragen von Gesundheit und Sicherheit. Sie soll für weitere Normen auf dem Gebiet Flüssigerdgas als Bezugsnorm dienen. Sie dient als Referenz für Personen, die LNG-Anlagen auslegen oder betreiben.

Pétrole et industries du gaz naturel - Caractéristiques du GNL influant sur la conception et le choix des matériaux (ISO 16903:2015)

L'ISO 16903:2015 donne des indications sur les caractéristiques du gaz naturel liquéfié (GNL) et sur les matériaux cryogéniques utilisés dans l'industrie du GNL. Elle donne également des indications sur la santé et la sécurité. Elle est destinée à servir de document de référence pour la mise en ?uvre des autres normes dans le domaine du gaz naturel liquéfié. Elle est destinée à servir de document de référence pour les personnes qui conçoivent ou exploitent des installations de GNL.

Industrija nafte in zemeljskega plina - Vpliv lastnosti utekočinjenega zemeljskega plina na načrtovanje in izbor materialov (ISO 16903:2015)

Ta evropski standard vsebuje smernice glede značilnosti utekočinjenega zemeljskega plina (LNG) in kriogenih materialov, ki se uporabljajo v industriji LNG. Podaja tudi smernice glede zdravstvenih in varnostnih zadev. Namenjen je uporabi kot referenčni dokument pri izvajanju drugih standardov CEN/TC 282 "Napeljave in oprema za utekočinjeni zemeljski plin". Namenjen je uporabi kot referenčni dokument za osebe, ki projektirajo ali upravljajo opremo LNG. (spremenjen bo v skladu s področjem uporabe standarda ISO 16903).
