Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

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.

Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting
a vote.
