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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

This second edition cancels and replaces the first edition (ISO 11363-1:2010), which has been technically
revised to allow option C by modifying Figure 2. It also incorporates the Technical Corrigenda

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 (and
external one on the valve stem and an internal one in the cylinder neck), both will have the same
nominal taper, thread pitch and thread profile.

of valves to gas cylinders —
Part 1:
Specifications
1 Scope

cylinders.
It does not cover the connection requirements for
— mechanical strength,
— gas tightness, and
— capability of repeated assembly and dismounting operations.
Gauge inspection is covered by ISO 11363-2.

3.1 General
3.1.1
basic profile
theoretical profile, when the profile of the external thread coincides with the profile of the internal thread
3.1.2
design profile
profile which differs from the basic profile due to the radius of the root, necessary for manufacturing
and strength requirements
Note 1 to entry: For such a profile, manufacturing tolerances are taken into account.

3.1.3
length of external thread
l
length of full form thread on the valve stem (3.1.8), measured along the cone axis from the reference
plane A (3.4.3)

length of internal thread
L
length of full form thread in the cylinder neck, measured along the cone axis from the reference
