Dieser Teil von ISO 17510 gilt für Masken, ihre Verbindungselemente und für Zubehörteile, die verwendet
werden, um ein Schlafapnoe-Atemtherapiegerät an den Patienten anzuschließen. Er legt Anforderungen an
Masken und Zubehörteile, einschließlich aller Verbindungselemente, fest, die erforderlich sind, um die
Patientenanschlussöffnung des Schlafapnoe-Atemtherapiegeräts mit einem Patienten zu verbinden, und die
bei Anwendung der Schlafapnoe-Atemtherapie eingesetzt werden, z. B. Nasenmasken, Abgasöffnungen und
Kopfgeschirr.
Schlafapnoe-Atemtherapiegeräte werden in ISO 17510-1 behandelt. Siehe auch Bild A.1, in dem die
typischen Bestandteile der beiden Teile von ISO 17510 dargestellt sind.

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 17510-2 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 17510-2:2003) 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

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 during use of this equipment.
ISO 17510-2 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 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 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.
Throughout this document, text for which a rationale is provided in Annex A is indicated by an asterisk (*).

Part 2:
Masks and application accessories
1 Scope
This part of ISO 17510 applies to masks, their fixing and to the accessories used to connect a sleep apnoea
breathing therapy equipment to the patient. It specifies requirements for masks and accessories, including any
connecting element, that are required to connect the patient connection port of sleep apnoea breathing
therapy equipment to a patient, and are used for the application of sleep apnoea breathing therapy, e.g. nasal
masks, exhaust ports and headgear.
Sleep apnoea breathing therapy equipment is covered by ISO 17510-1. See Figure A.1 for typical elements of
the two parts of ISO 17510.
This part of ISO 17510 does not cover oral appliances.
