Safety devices for protection against excessive pressure - Part 7: Common data (ISO 4126-7:2013)

ISO 4126-7:2013 specifies requirements for safety valves. It contains information which is common to ISO 4126-1 to ISO 4126-6 to avoid unnecessary repetition.

Sicherheitseinrichtungen gegen unzulässigen Überdruck - Teil 7: Allgemeine Daten (ISO 4126-7:2013)

Dieser Teil von ISO 4126 legt Anforderungen an Sicherheitsventile fest. Er enthält zur Vermeidung unnötiger Wiederholungen Daten, die den Teilen 1 bis 6 der ISO 4126 gemein sind.
Zu ausdampfenden Flüssigkeiten oder Zweiphasengemischen siehe ISO 4126-10.
Der Anwender wird darauf hingewiesen, dass die Verwendung der in 6.3 angegebenen allgemeinen Gasgleichung nicht empfohlen wird, wenn die Abblasetemperatur mehr als 90 % der thermodynamischen kritischen Temperatur und der Abblasedruck mehr als 50 % des thermodynamischen kritischen Drucks beträgt. Darüber hinaus wird die Kondensation nicht berücksichtigt. Bei Auftreten von Kondensation sollte das in 6.3 angegebene Verfahren nicht angewendet werden.

Dispositifs de sécurité pour protection contre les pressions excessives - Partie 7: Données communes (ISO 4126-7:2013)

L'ISO 4126-5:2013 spécifie des exigences pour les soupapes de sûreté. Elle contient des données qui sont communes aux parties 1 à 6 de l'ISO 4126 pour éviter les répétitions inutiles.
Pour les liquides auto-vaporisants ou les mélanges biphasiques, voir l'ISO 4126‑10.

Naprave za varovanje pred visokim tlakom - 7. del: Splošni podatki (ISO 4126-7:2013)

Ta del standarda ISO 4126 vsebuje informacije, ki so enake za dele od 1 do 6 standarda ISO 4126, da se ne ponavljajo brez potrebe. Uporabnika opozarjamo, da ni priporočena uporaba formule idealnega plina iz točke 6.3, ko je temperatura za razbremenitev večja od 90 % termodinamične kritične temperature in tlak za razbremenitev večji od 50 % termodinamičnega kritičnega tlaka. Poleg tega se kondenzacija ne upošteva. Če pride do kondenzacije, se metoda iz točke 6.3 ne sme uporabiti.
