DESCRIPTION

BS EN ISO 17879:2017


This standard BS EN ISO 17879:2017 Gas cylinders. Self-closing cylinder valves. Specification and type testing is classified in these ICS categories:
  • 23.020.30 Gas pressure vessels, gas cylinders
  • 23.020.35 Gas cylinders

This document 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.

This document 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 .

This document 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.
