45 Foreword
46 ISO (the International Organization for Standardization) is a worldwide federation of national standards
47 bodies (ISO member bodies). The work of preparing International Standards is normally carried out
48 through ISO technical committees. Each member body interested in a subject for which a technical
49 committee has been established has the right to be represented on that committee. International
50 organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO
51 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
52 electrotechnical standardization.
53 The procedures used to develop this document and those intended for its further maintenance are
54 described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
55 different types of ISO documents should be noted. This document was drafted in accordance with the
56 editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
57 Attention is drawn to the possibility that some of the elements of this document may be the subject of
58 patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any
59 patent rights identified during the development of the document will be in the Introduction and/or on
60 the ISO list of patent declarations received (see www.iso.org/patents).
61 Any trade name used in this document is information given for the convenience of users and does not
62 constitute an endorsement.
63 For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
64 expressions related to conformity assessment, as well as information about ISO's adherence to the World
65 Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see
66 www.iso.org/iso/foreword.html.
67 This document was prepared by Technical Committee ISO/TC 121 Anaesthetic and respiratory equipment
68 Subcommittee SC 6, Medical gas supply systems in collaboration with the European Committee for
69 Standardization (CEN) Technical Committee CEN/TC 215, Respiratory and anaesthetic equipment, in
70 accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
71 This first edition together with ISO 18777-1 replaces ISO 18777:2005, which has been technically revised.
72 The main changes are as follows:
73 ⎯ The standard has been split into two distinct parts:
74 • Part 1 - Common requirements and particular requirements for base units and
75 • Part 2 – Particular requirements for Portable units.
76 ⎯ Requirements that are common to both base units and portable units are specified in part 1
77 and cross referred to in this document.
78 ⎯ The format of the document has been changed from the IEC to the ISO format.
79 ⎯ Requirements for the filling port connector have been included.
80 A list of all parts in the ISO 18777 series can be found on the ISO website.
