Gas cylinders - Residual pressure valves - General requirements and type testing
ISO 15996:2005 specifies requirements for residual pressure valves, with or without a non-return function, for gas cylinders and the methods of testing such valves, for type approval. ISO 15996:2005 is applicable to valves to be fitted to gas cylinders of up to 150 l water capacity, intended to contain compressed, liquefied or dissolved gases. ISO 15996:2005 does not cover valves for fire extinguishers, cryogenic equipment or liquefied petroleum gas.

<p>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:</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>which convey compressed or liquefied gases.</p> <p>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.</p> <p>These requirements are in addition to those in ISO 10297.</p> <p>For RPD stand-alone devices this document can also be applied.</p> <p>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).</p>
