ISO 17510-1:2007(E)
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 17510-1 was prepared by Technical Committee ISO/TC 121, Anaesthetic and respiratory equipment,
Subcommittee SC 3, Lung ventilators and related equipment.
This second edition cancels and replaces the first edition (ISO 17510-1:2002) which has been technically
revised.
ISO 17510 consists of the following parts, under the general title Sleep apnoea breathing therapy:
⎯ Part 1: Sleep apnoea breathing therapy equipment
⎯ Part 2: Masks and application accessories
ISO 17510-1:2007(E)
Introduction
Sleep apnoea is the clinically significant intermittent absences of normal respiration occurring during sleep.
The awareness of the risks associated with sleep apnoea has grown significantly in recent years. As a result,
the use of sleep apnoea breathing therapy equipment has become common. This document covers basic
safety and essential performance requirements needed to protect patients in the use of this equipment.
This document 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 document for the
safety of 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 electrical 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 Standard can be found in IEC 60601-1:1988, 1.5 and A.2,
respectively.
To facilitate the use of this document, the following drafting conventions have been applied.
This document 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 document.
⎯ “Addition” means that the relevant text of this document is supplementary to the requirements of the
General Standard.
⎯ “Amendment” means that existing text of the General Standard is modified as indicated by the text of this
document.
To avoid confusion with any amendments to the General Standard itself, a particular numbering has been
employed for elements added by this document: 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.
Throughout this document, text for which a rationale is provided in Annex AA is indicated by an asterisk (*).
