DESCRIPTION

BS EN ISO 22434:2022


This standard BS EN ISO 22434:2022 Gas cylinders. Inspection and maintenance of valves is classified in these ICS categories:
  • 23.060.01 Valves in general
  • 23.020.35 Gas cylinders
This document specifies requirements for the inspection and maintenance of valves [including ball valves and valves with integrated pressure regulator (VIPRs)] for: a) refillable transportable gas cylinders; b) cylinder bundles; c) pressure drums and tubes; which convey compressed, liquefied or dissolved gases. This document does not apply to valves for liquefied petroleum gas (LPG). NOTE       Where there is no risk of ambiguity, gas cylinders, cylinder bundles, pressure drums and tubes are addressed with the collective term “gas cylinders” within this document. This document is applicable to valves reused at the time of the periodic inspection of gas cylinders, cylinder bundles, pressure drums and tubes, and can be applied at any other time, e.g. at a change of gas service (see ISO 11621). This document does not apply to the routine inspection of valves, e.g. carried out at the time of a gas cylinder filling.
