Annotation of standard text ÖNORM EN ISO 21922 :

Diese Internationale Norm legt die Sicherheitsanforderungen, bestimmte funktionale Anforderungen und die Kennzeichnung von Anforderungen und anderen Bauteilen, im Folgenden kurz Ventile genannt, für die Verwendung in Kälteanlagen einschließlich Wärmepumpen fest. Ventile im Sinne dieser Norm beinhalten Verlängerungsrohre. Die Norm beschreibt das Verfahren, das bei der Konstruktion von druckbeanspruchten Ventilen zugrunde zu legen ist, sowie die bei der Auswahl von Werkstoffen für Ventilteile zu berücksichtigenden Kriterien. Die Norm beschreibt Methoden, nach denen reduzierte Werte für die Kerbschlagarbeit bei niedriger Temperatur auf sichere Art und Weise berücksichtigt werden können. Diese Norm gilt für die Konstruktion von Gehäusen und Oberteilen für Druckentlastungseinrichtungen, einschließlich Berstscheibeneinrichtungen, im Hinblick auf die Druckfestigkeit, sie gilt jedoch nicht für andere Aspekte der Konstruktion oder die Anwendung von Druckentlastungseinrichtungen.
