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 21969 was prepared by Technical Committee ISO/TC 121, Anaesthetic and respiratory equipment,

Subcommittee SC 6, Medical gas systems.

This second edition cancels and replaces the first edition (ISO 21969:2005) which has been technically

revised.

Annex A contains rationale statements for some of the requirements of this International Standard. It is

included to provide additional insight into the reasoning that led to the requirements and recommendations

that have been incorporated in this International Standard. The clauses and subclauses marked with an

asterisk (*) after their number have corresponding rationale contained in Annex A. It is considered that

knowledge of the reasons for the requirements will not only facilitate the proper application of this International

Standard, but will also expedite any subsequent revision.
