Gas cylinders - Self-closing cylinder valves - Specification and type testing (ISO 17879:2017)
ISO 17879:2017 specifies the design, type testing, marking and manufacturing tests and examinations requirements for self-closing cylinder valves intended to be fitted to refillable transportable gas cylinders which convey compressed, liquefied or dissolved gases.
NOTE 1 The main applications for such self-closing cylinder valves are in the calibration gas and beverage industries.
ISO 17879:2017 covers the function of a self-closing cylinder valve as a closure.
NOTE 2 Requirements for standard cylinder valves are given in ISO 10297. Requirements for quick-release cylinder valves are given in ISO 17871.
ISO 17879:2017 is not applicable to self-closing cylinder valves for cryogenic equipment, for portable fire extinguishers, or for liquefied petroleum gas (LPG).
NOTE 3 Requirements for valves for cryogenic vessels are specified in ISO 21011 and at a regional level, for example, in EN 1626. Requirements for valves for portable fire extinguishers at a regional level are specified, for example, in EN 3 series. Requirements for self-closing LPG cylinder valves are specified in ISO 14245.
NOTE 4 Additional requirements for pressure-relief devices might be specified in international/regional regulations/standards.

Bouteilles à gaz - Robinets de bouteilles équipés de clapets auto-obturants - Spécifications et essais de type (ISO 17879:2017)
ISO 17879:2017 spécifie les exigences relatives à la conception, aux essais de type, au marquage, ainsi qu'aux essais et examens en cours de fabrication, pour les robinets de bouteilles équipés de clapets auto-obturants destinés à être montés sur des bouteilles à gaz transportables et rechargeables qui sont conçues pour transporter des gaz comprimés, liquéfiés ou dissous.
NOTE 1 Les applications principales de ces robinets de bouteilles équipés de clapets auto-obturants sont les gaz d'étalonnage et le secteur des boissons.
ISO 17879:2017 couvre la fonction d'un robinet de bouteille équipé d'un clapet auto-obturant en tant que dispositif de fermeture.
NOTE 2 Les exigences relatives aux robinets de bouteilles normalisés sont fournies dans l'ISO 10297. Les exigences relatives aux robinets de bouteilles à ouverture rapide sont fournies dans l'ISO 17871.
ISO 17879:2017 ne s'applique pas aux robinets de bouteilles équipés de clapets auto-obturants utilisés sur des équipements cryogéniques, sur des extincteurs d'incendie portatifs ou sur des équipements transportant du gaz de pétrole liquéfié (GPL).
NOTE 3 Les exigences portant sur les robinets pour récipients cryogéniques sont spécifiées dans l'ISO 21011 et, au niveau régional, par exemple dans l'EN 1626. Les exigences portant sur les robinets pour extincteurs d'incendie portatifs au niveau régional sont spécifiées, par exemple, dans la série EN 3. Les exigences relatives aux robinets de bouteilles de GPL équipés de clapets auto-obturants sont spécifiées dans l'ISO 14245.
NOTE 4 Pour les dispositifs limiteurs de pression, des exigences supplémentaires peuvent être spécifiées dans les normes ou dans les règlements internationaux/régionaux.
Plinske jeklenke - Samozaporni ventili za plinske jeklenke - Specifikacija in preskus tipa (ISO 17879:2017)
Ta dokument določa projektiranje, tipsko preskušanje, označevanje in proizvodne preskuse ter zahteve za preglede za samozaporne ventile jeklenk, ki so predvideni za namestitev na prenosne plinske jeklenke, ki jih je mogoče znova napolniti in so z njimi prenašani stisnjeni, utekočinjeni ali raztopljeni plini.
OPOMBA 1: Tovrstni samozaporni ventili jeklenk se uporabljajo predvsem v industriji za kalibracijski plin in tekočine.
Ta dokument zajema funkcijo samozapornega ventila jeklenke kot zapore.
OPOMBA 2: Zahteve za standardne ventile za jeklenke so podane v standardu ISO 10297. Zahteve za ventile za hitro sprostitev za jeklenke so navedene v standardu ISO 17871.
Ta dokument se ne uporablja za samozaporne ventile jeklenk za kriogensko opremo, prenosne gasilnike ali utekočinjeni naftni plin (LPG).
OPOMBA 3: Zahteve za ventile kriogenskih posod so določene v standardu ISO 21011 in na regionalni ravni, npr. v standardu EN 1626. Zahteve za ventile za prenosne gasilnike na regionalni ravni so določene npr. v skupini EN 3. Zahteve za samozaporne ventile jeklenk LPG so določene v standardu ISO 14245.
OPOMBA 4: Dodatne zahteve za naprave za razbremenitev tlaka so morda določene v mednarodnih/regionalnih
predpisih/standardih.
