Introduction
Gas cylinders intended to contain compressed, liquefied or dissolved gas under pressure are fitted
with accessories to allow release and refilling of gas. Hereinafter, the term “valve” will apply to such
accessories.
Where the connection between cylinder and valve is obtained by assembly of two taper threads (an
external one on the valve stem and an internal one in the cylinder neck), both shall have the same
nominal taper, thread pitch and thread profile.

Publication as an International Standard requires approval by at least 75 % of the member bodies casting
a vote.

1 Scope
This part of ISO 11363 specifies types, dimensions and principles of use of gauges, to be used in
conjunction with the taper threads specified in ISO 11363-1 (i.e. 17E and 25E threads).
It provides examples of calculations for thread gauge dimensions on the large end diameter (Annex A)
and draws attention to the limitations of the gauging system specified (Annex B).
