Gas cylinders - Cylinder valves - Manufacturing tests and examinations
ISO 14246:2014 specifies the procedures and acceptance criteria for manufacturing testing and examination of cylinder valves that have been manufactured to achieve type approval. ISO 14246:2014 is applicable to cylinder valves intended to be fitted to refillable transportable gas cylinders, main valves (excluding ball valves) for cylinder bundles and cylinder valves or main valves with integrated pressure regulator (VIPR) designed and type tested according to ISO 10297.

<p> La présente norme spécifie les exigences pour les essais et contrôles des robinets des bouteilles à gaz lors de la fabrication. La présente norme est applicable aux robinets destinés à être montés sur les bouteilles pour gaz industriels et médicaux de contenance en eau jusqu'à 150 l, destinées aux gaz comprimés, liquéfiés ou dissous. La présente norme n'est applicable qu'aux robinets manoeuvrables par un volant à main ou une clé. La présente norme n'est pas applicable aux robinets pour équipement respiratoire, extincteurs, équipement cryogénique et gaz de pétrole liquéfié (GPL). </p>
<p>This document specifies the procedures and acceptance criteria for manufacturing tests and examinations (sometimes called "initial inspection and tests") of valves designed and type tested in accordance with ISO 10297.</p> <p>This document is applicable to:</p> <p>a) cylinder valves intended to be fitted to refillable transportable gas cylinders;</p> <p>b) main valves (excluding ball valves) for cylinder bundles;</p> <p>c) cylinder valves or main valves with integrated pressure regulator (VIPR);</p> <p>d) valves for pressure drums and tubes.</p> <p>NOTE Where there is no risk of ambiguity, cylinder valves, main valves, VIPR and valves for pressure drums and tubes are addressed with the collective term “valves” within this document.</p> <p>The principles of these manufacturing tests and examinations can be beneficially applied to cylinder valves type tested to national or International Standards other than ISO 10297.</p>
