Gas cylinders - Specifications and testing of LPG cylinder valves - Manually operated (ISO 15995:2021)
This document specifies the requirements for design, specification, type testing and production testing and inspection of dedicated LPG manually operated cylinder valves for use with and directly connected to transportable refillable LPG cylinders.
It also includes requirements for associated equipment for vapour and liquid service. Bursting discs and/or fusible plugs are not covered in this document.
Annex B identifies requirements for production testing and inspection.
This document excludes other LPG cylinder devices which are not an integral part of the dedicated manually operated cylinder valve.
This document does not apply to cylinder valves for fixed automotive installations and ball valves.
NOTE For self-closing LPG cylinder valves see ISO 14245. For cylinder valves for compressed, dissolved and other liquefied gases see ISO 10297,[2] ISO 17871[6] or ISO 17879[7].

Dieses Dokument legt Anforderungen an Auslegung, Spezifikation, Baumusterprüfung sowie Produktions¬prüfung und Inspektion von handbetätigten Flaschenventilen für Flüssiggas (LPG, en: Liquefied Petroleum Gas) zur Verwendung mit ortsbeweglichen, wiederbefüllbaren LPG-Flaschen fest, an denen die Ventile direkt angeschlossen sind.
Es enthält auch Anforderungen an zugehöriges Zubehör für den Betrieb in der Gas- und Flüssigphase. Berstscheiben und/oder Schmelzsicherungen werden nicht von diesem Dokument abgedeckt.
Anhang B enthält Anforderungen an die Produktionsprüfung und Inspektion.
Dieses Dokument schließt andere LPG-Flascheneinrichtungen aus, die keinen integralen Teil des hand-betätigten Flaschenventils darstellen.
Dieses Dokument gilt nicht für in Fahrzeugen fest eingebaute Flaschenventile und Kugelventile.
ANMERKUNG Für selbstschließende LPG-Flaschenventile siehe ISO 14245. Für Flaschenventile für verdichtete, gelöste und andere verflüssigte Gase siehe ISO 10297 [2], ISO 17871 [6] oder ISO 17879 [7].
Bouteilles à gaz - Spécifications et essais pour valves de bouteilles de GPL - Fermeture manuelle (ISO 15995:2021)
Le présent document spécifie les exigences de conception, les spécifications, les essais de type et les essais et contrôles en production des robinets de bouteilles de GPL dédiés à fonctionnement manuel, destinés à être utilisés avec, et directement raccordés à, des bouteilles de GPL transportables rechargeables.
Le présent document comprend également des exigences relatives aux équipements associés pour le service en phases gazeuse et liquide. Les disques de rupture et/ou les bouchons fusibles ne sont pas couverts par le présent document.
L'Annexe B précise les exigences relatives aux essais et contrôles en production.
Le présent document exclut les autres dispositifs pour bouteilles de GPL qui ne font pas partie intégrante du robinet de bouteille dédié à fonctionnement manuel.
Le présent document ne s'applique pas aux robinets de bouteilles pour installations automobiles fixes, ni aux robinets à tournant sphérique.
NOTE Pour les valves de bouteilles de GPL à fermeture automatique, voir l'ISO 14245. Pour les robinets de bouteilles pour gaz comprimés, dissous et autres gaz liquéfiés, voir l'ISO 10297[2], l'ISO 17871[6] ou l'ISO 17879[7].
