1 Scope
This International Standard describes the procedures and acceptance criteria for manufacturing
testing and examination (sometimes called initial inspection and tests) of cylinder
valves that have been manufactured according to type approvals.
This International Standard is applicable to
-
a) cylinder valves intended to be fitted to refillable transportable gas cylinders,
-
b) main valves (excluding ball valves) for cylinder bundles, and
-
c) cylinder valves or main valves with integrated pressure regulator (VIPR)
designed and type tested according to ISO 10297.
NOTE Where there is no risk of ambiguity, cylinder valves, main valves and VIPR are addressed
with the collective term “valves” within this document.
The principles of these tests and examinations can be beneficially applied to cylinder
valves type tested to national or International Standards other than ISO 10297.
