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 58, Gas cylinders, Subcommittee SC 2,
Cylinder fittings.
This second edition cancels and replaces the first edition (ISO 16964:2015), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— Test 1 for the safety cable has been clarified;
— the leak test has been corrected;
— the pressure cycle test has been clarified;
— the test apparatus for the torsion test, as shown in Figures A.6 and A.7 has been clarified.

ISO 16964:2019(E)
Introduction
Flexible hose assemblies are used to transfer industrial and medical gases into cylinders, bundles,
MEGCs and trailers (battery vehicles), and also to supply such gases to user equipment.
There is a range of existing International Standards to be used for specific applications or hose
construction:
— ISO 14113 which covers hoses made with internal rubber or plastics tubing and used to supply gases
to customers for welding applications;
— ISO 21969 which covers hoses with an internal corrugated metallic liner and used to supply medical
gases to customers;
— ISO 10380 which covers hoses with internal corrugated metallic liner for all applications including
non-industrial and medical gases.
ISO 14113 and ISO 21969 cover only specific customer applications and are intended to be used
accordingly, while ISO 10380 is general in its approach.
The intent of the document is to describe flexible hoses not defined in the specific applications
documents mentioned above.
INTERNATIONAL STANDARD ISO 16964:2019(E)
Gas cylinders — Flexible hoses assemblies — Specification
and testing
1 Scope
This document provides specification and testing requirements for high pressure flexible hose
assemblies intended to be connected to gas cylinders, bundles of cylinders or trailers (battery vehicles),
and MEGCs for use when filling and emptying gas at production sites and also for customer use. This
document applies to flexible hose assemblies with rated pressures up to 1 000 bar for use in the
temperature range of −40 °C to +65 °C.
This document is not applicable to:
— rubber and plastics flexible hose assemblies for welding, cutting and related processes up to 45 MPa
(450 bar) for customer use (see ISO 14113);
— high pressure flexible hose assemblies for use with medical gas systems for customer use (see
ISO 21969);
— low pressure hose assemblies for use with medical gases for customer use (see ISO 5359);
— rubber and thermoplastic low pressure hose assemblies for welding, cutting and related processes
for customer use (see ISO
