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 document was prepared by Technical Committee ISO/TC 44, Welding and allied processes,
Subcommittee SC 8, Equipment for gas welding, cutting and allied processes.
This third edition cancels and replaces the second edition (ISO 14114:2014), which has been technically
revised with the following changes:
a) Clause 3 has been restructured;
b) 4.1 has been revised;

INTERNATIONAL STANDARD ISO 14114:2017(E)
Gas welding equipment — Acetylene manifold systems
for welding, cutting and allied processes — General
requirements
1 Scope
This document applies to acetylene cylinder manifold systems extending from the cylinder valve or the
bundle outlet connections to the outlet connection of the main shut-off valve. It specifies requirements
for design, materials and testing of cylinder manifold systems for the supply of acetylene for use in
welding, cutting and allied processes.
This document applies to acetylene cylinder manifold systems in which acetylene single cylinders or
acetylene bundles are coupled for collective gas withdrawal.
NOTE National regulations exist regarding limitation of the amount of single cylinders/bundles of acetylene
on a single location (e.g. in warehouse or connected to a manifold system).
This document also covers a test procedure for decomposition blockers.
