(Main)Gas cylinders - Residual pressure valves - Specification and type testing of cylinder valves incorporating residual pressure devices (ISO 15996:2017)
Gas cylinders - Residual pressure valves - Specification and type testing of cylinder valves incorporating residual pressure devices (ISO 15996:2017)
ISO 15996:2017 specifies design, type testing and marking requirements for cylinder valves incorporating residual pressure devices, hereinafter referred to as residual pressure valves (RPVs). This document applies to the following types of RPVs:
a) cylinder valves intended to be fitted to refillable transportable gas cylinders;
b) main valves (excluding ball valves) for cylinder bundles;
c) cylinder valves or main valves with integrated pressure regulator (VIPR);
d) valves for pressure drums and tubes;
which convey compressed or liquefied gases.
NOTE Where there is no risk of ambiguity, cylinders, pressure drums, tubes and cylinder bundles are addressed with the collective term "cylinder" within this document.
These requirements are in addition to those in ISO 10297.
For RPD stand-alone devices this document can also be applied.
ISO 15996:2017 does not apply to RPVs for portable fire extinguishers, cryogenic equipment, low pressure refrigerant gases (cylinder test pressure less than 50 bar), dissolved gases or liquefied petroleum gas (LPG).
Gasflaschen - Restdruckventile - Spezifikation und Baumusterprüfungen von Flaschenventilen mit integrierten Restdruckeinrichtungen (ISO 15996:2017)
Diese Internationale Norm legt Anforderungen an die Auslegung, Baumusterprüfung und Kennzeichnung von Ventilen mit integrierten Restdruckeinrichtungen fest, die im Folgenden Restdruckventile (RPV) genannt werden. Diese Internationale Norm gilt für folgende RPV Typen:
a) Flaschenventile zur Anbringung an wiederbefüllbare ortsbewegliche Gasflaschen;
b) Hauptabsperrventile (ausgenommen Kugelhähne) für Flaschenbündel;
c) Flaschen oder Hauptabsperrventile mit integriertem Druckregler (VIPR, en: valves with integrated pressure regulator);
d) Ventile für Druckfässer und Großflaschen;
die verdichtete oder verflüssigte Gase befördern.
Diese Internationale Norm gilt nicht für Restdruckventile (RPV) für tragbare Feuerlöscher, Kryo Zubehör, Niedrigdruck-Kältemittelgase (Prüfdruck des Druckgefäßes niedriger als 50 bar) oder Flüssiggas (LPG).
Bouteilles à gaz - Robinets à pression résiduelle - Spécifications et essais de type de robinets de bouteille intégrant des dispositifs de pression résiduelle (ISO 15996:2017)
ISO 15996:2017 spécifie les exigences applicables à la conception, aux essais de type et au marquage des robinets de bouteille comportant des dispositifs de pression résiduelle, désignés dans le présent document par le terme «robinets à pression résiduelle» (RPV). Le présent document s'applique aux types de RPV suivants:
a) les robinets de bouteille destinés à être montés sur des bouteilles à gaz transportables rechargeables;
b) les vannes principales (à l'exception des robinets à boisseau sphérique) pour cadres de bouteilles;
c) les robinets de bouteille ou robinets de bouteille à détendeur intégré (VIPR);
d) les robinets pour les fûts à pression et les tubes;
utilisés pour transporter des gaz comprimés ou liquéfiés.
NOTE Lorsqu'il n'existe aucun risque d'ambiguïté, les bouteilles, fûts à pression, tubes et cadres de bouteilles sont désignés par le terme générique «bouteille» dans le présent document.
Ces exigences s'ajoutent à celles de l'ISO 10297.
ISO 15996:2017 peut également être appliqué aux dispositifs RPD autonomes.
Le présent document ne s'applique pas aux RPV destinés aux extincteurs d'incendie portables, aux équipements cryogéniques, aux gaz réfrigérants à basse pression (pression d'épreuve de la bouteille inférieure à 50 bar), aux gaz dissous ou aux gaz de pétrole liquéfié (GPL).
Plinske jeklenke - Ventili za zagotavljanje ostanka tlaka - Specifikacija in preskus tipa ventilov za jeklenke z elementom za zagotavljanje ostanka tlaka (ISO 15996:2017)
ISO 15996:2005 določa zahteve za preostale tlačne ventile s funkcijo vračanja ali brez nje za plinske jeklenke in načine preskušanja takšnih ventilov za tipsko odobritev.
ISO 15996:2005 se uporablja pri ventilih, ki bodo nameščeni na plinske jeklenke s kapaciteto do 150 l, ki so predvidene za stisnjene, utekočinjene ali raztopljene pline.
ISO 15996:2005 ne obsega ventilov za gasilnike, kriogensko opremo ali utekočinjeni naftni plin.
