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 10651-6 was prepared by Technical Committee ISO/TC 121, Anaesthetic and respiratory equipment,
Subcommittee SC 3, Lung ventilators and related equipment.
This first edition of ISO 10651-6, together with the second edition of ISO 10651-2, cancels and replaces the
first edition of ISO 10651-2:1996, which has been technically revised.
ISO 10651 consists of the following parts, under the general title Lung ventilators for medical use — Particular
requirements for basic safety and essential performance:
 Part 2: Home care ventilators for ventilator-dependent patients
 Part 3: Particular requirements for emergency and transport ventilators
 Part 4: Particular requirements for operator-powered resuscitators
 Part 6: Home care ventilatory support devices
The following part is under preparation:
 Part 5: Gas-powered emergency resuscitators
NOTE ISO 10651-1:1993, Lung ventilators for medical use — Part 1: Requirements, was withdrawn in 2001 and has
been revised as IEC 60601-2-12:2003, Medical electrical equipment — Part 2-12: Particular requirements for the safety of
lung ventilators — Critical care ventilators.

ISO 10651-6:2004(E)
Introduction
This part of ISO 10651 specifies requirements for ventilatory support devices mainly for home-care use but
which could be used elsewhere (in healthcare facilities or other locations) for patients not dependent on
ventilatory support, i.e. where the ventilator is not considered to be life-supporting equipment. These
ventilators are frequently used in locations where driving power is not reliable. These ventilators often are
supervised by non-healthcare personnel with varying levels of training.
This part of ISO 10651 is a Particular Standard based on IEC 60601-1:1988, including Amendments 1 (1991)
and 2 (1995), hereafter referred to as the General Standard. The General Standard is the basic standard for
the safety of all medical electrical equipment used by or under the supervision of qualified personnel in the
general medical and patient environment; it also contains certain requirements for reliable operation to ensure
safety.
The General Standard has associated Collateral Standards and Particular Standards. The Collateral
Standards include requirements for specific technologies and/or hazards and apply to all applicable equipment,
such as medical systems, EMC, radiation protection in diagnostic X-ray equipment, software, etc. The
Particular Standards apply to specific equipment types, such as medical electron accelerators, high frequency
surgical equipment, hospital beds, etc.
NOTE Definitions of Collateral Standard and Particular Standards can be found in IEC 60601-1:1988, 1.5 and A.2,
respectively.
To facilitate the use of this part of ISO 10651, the following drafting conventions have been applied.
This part of ISO 10651 uses the same main clause titles and numbering as the General Standard, for ease of
cross-referencing of the requirements. The changes to the text of the General Standard, as supplemented by
the Collateral Standards, are specified by the use of the following words.
 “Replacement” means that the indicated clause or subclause of the General Standard is replaced
completely by the text of this Particular Standard.
 “Addition” means that the relevant text of this Particular Standard is a new element (e.g. subclause, list
item, note, table, figure) additional to the General Standard.
 “Amendment” means that an existing element of the General Standard is partially modified by deletion
and/or addition as indicated by the text of this Particular Standard.
To avoid confusion with any amendments to the General Standard itself, a particular numbering has been
employed for elements added by this part of ISO 10651: clauses, subclauses, tables and figures are
numbered starting from 101; additional list items are lettered aa), bb), etc. and additional annexes are
lettered AA, BB, etc.
In this part of ISO 10651, the following print types are used:
 requirements, compliance with which can be verified, and definitions: roman type;
 notes and examples: smaller roman type;
 description of type of document change, and test methods: italic type;
 terms defined in the General Standard IEC 60601-1:1988, Clause 2 and terms defined in this part of
ISO 10651: bold type.

1 Scope
IEC 60601-1:1988, Clause 1 applies, except as follows.
Amendment:
This part of ISO 10651 specifies the basic safety and essential performance requirements for home-care
ventilatory support devices, intended mainly for use in home care but which could be used elsewhere (e.g. in
healthcare facilities) for appropriate patients for whom the use of a home-care ventilator complying with
ISO 10651-2 is not required.
The requirements of this part of ISO 10651 which replace or modify the requirements of IEC 60601-1:1988
and its Amendments 1 (1991) and 2 (1995) are intended to take precedence over the corresponding general
requirements.

10.101 Pneumatic driving power supplies
If the ventilator is intended to be connected to a medical gas pipeline system complying with ISO 7396-1, it
shall operate and meet the requirements of this part of ISO 10651 throughout a pressure range of 280 kPa to
600 kPa, and shall cause no safety hazard with inlet pressures up to 1 000 kPa. The gas flowrate measured at
the ventilator’s high-pressure input port shall not exceed 60 l/min (time-weighted average over 10 s) at a
pressure of 280 kPa under normal condition. Further, the transient flow requirement shall not exceed the
equivalent of 200 l/min for 3 s.
NOTE Flowrate values are expressed under ATPD conditions.
