Lung ventilators for medical use — Part 1: Requirements

Is to be used in conjunction with IEC 601-1:1988. Specifies relevant requirements (general requirements, environmental conditions, protection against electric shock hazards, protection against excessive temperatures and other safety hazards, accuracy of operating data and protection against hazardous output, constructional requirements, additional requirements) for lung ventilators, excluding ventilators primarily intended for anaesthesia, home care, transport, and other devices such as jet and high-frequency ventilators. The requirements of this standard take precedence over those of IEC 601-1.

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. Esch 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, govern-
mental and non-governmental, in liaison with ISO, also take patt in the
work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an Inter-
national Standard requires approval by at least 75 % of the member
bodies casting a vote.
International Standard ISO 106514 was prepared by Technical Commit-
tee ISO/TC 121, Anaesthetic and respiratory equipment, Sub-Committee
SC 3, Lung ventiiators and related equipment.
This fit-st edition of ISO 10651-1 cancels and replaces the first edition of
of ISO 5369, published in 1988, and IEC 601-2-12:1988, of both of which
it constitutes a technical revision and amplification.
ISO 10651 consists of the following Parts, under the general title Lung
ventilators for medical use:
- Part 1: Requirements
