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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International 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.
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.
ISO 11114-1 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 23, Transportable gas cylinders, in collaboration with ISO Technical Committee ISO/TC 58, Gas
cylinders, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna
Agreement).
This second edition cancels and replaces the first edition (ISO 11114-1:1997), which has been technically
revised. The main changes resulting from the revision of this part of ISO 11114 are
the term “not recommended” has been replaced by “not acceptable”,
the text has been clarified,
a requirement for gas mixtures has been introduced.
ISO 11114 consists of the following parts, under the general title Gas cylinders — Compatibility of cylinder and
valve materials with gas contents:
Part 1: Metallic materials
Part 2: Non-metallic materials
Part 3: Autogenous ignition test for non-metallic materials in oxygen atmosphere
Part 4: Test methods for selecting metallic materials resistant to hydrogen embrittlement

ISO 11114-1:2012(E)
Introduction
Industrial, medical and special gases (e.g. high-purity gases, calibration gases) can be transported or stored
in gas cylinders. An essential requirement of the material from which such gas cylinders and their valves are
manufactured is compatibility with the gas content.
Compatibility of cylinder materials with gas content has been established over many years by practical
application and experience. Existing national and international regulations and standards do not fully cover
this aspect.
This part of ISO 11114 is based on current international experience and knowledge.
Where there is any conflict between this International Standard and any applicable regulation, the regulation
always takes precedence.
This part of ISO 11114 has been written to be in conformity with the UN Recommendations on the Transport
of Dangerous Goods: Model Regulations. When published it will be submitted to the UN Sub Committee of
Experts on the Transport of Dangerous Goods with a request that it be included in the Model Regulations.
