Dentistry - Dental units - Part 2: Water and air supply (ISO 7494-2:2003)
ISO 7494-2:2003 specifies requirements and test methods for the materials, design and construction of the water and air supply within dental units in order to ensure that the compressed water and air supplied via the dental unit are of appropriate quality. It includes provisions for the prevention of retraction of oral fluids into the water supply of the dental unit.
ISO 7494-2:2003 does not address prevention of contamination and/or proliferation of hazardous microorganisms (for example bacteria, viruses) in the dental unit.

1 Anwendungsbereich
In diesem Teil von ISO 7494 werden Anforderungen an und Prüfverfahren für das Material, die Gestaltung und die Konstruktion von Wasser- und Luftvorsorgungen innerhalb der zahnärztlichen Behandlungsgeräte festgelegt, um sicherzustellen, dass das von dem zahnärztlichen Behandlungsgerät abgegebene Wasser und die komprimierte Luft eine einwandfreie Qualität besitzen. Festgelegt sind Schutzmaßnahmen, um eine Rücksaugung der Mundhöhlenflüssigkeiten in die Wasserversorgung des Behandlungsgerätes zu verhindern.
Dieser Teil von ISO 7494 beschreibt nicht, wie eine Kontamination und/oder Ausbreitung von gefährlichen Mikroorganismen (z. B. Bakterien, Viren) in den zahnärztlichen Behandlungsgeräten verhindert werden kann
Art dentaire - Units dentaires - Partie 2: Alimentation en eau et en air (ISO 7494-2:2003)
L'ISO 7494-2:2004 spécifie les exigences et les méthodes d'essai applicables aux matériaux, à la conception et à la construction de l'alimentation en eau et en air de l'unit dentaire de manière que l'eau et l'air comprimé fournis par l'intermédiaire de l'unit soient de qualité appropriée. Elle comporte des dispositions relatives à la prévention de la rétraction des fluides buccaux dans l'alimentation en eau de l'unit dentaire.
L'ISO 7494-2:2004 ne traite ni de la prévention de toute contamination, ni de la prévention de prolifération de micro-organismes dangereux (par exemple bactéries, virus) dans l'unit dentaire.

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 7494-2 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 6, Dental
equipment.
This first edition of ISO 7494-2, together with ISO 7494-1, cancels and replaces ISO 7494:1996, which has
been technically revised.
ISO 7494 consists of the following parts, under the general title Dentistry — Dental units:
Part 2: Water and air supply

Introduction
The requirements for water and air supply of dental units have been discussed extensively in
TC 106/SC 6/WG 2, and it was concluded that the technical specifications for the water and air lines within
dental units are sufficiently defined while the microbiological side of the problem is not addressed.
The formulation of criteria in order to avoid or reduce biofilm on the surfaces in water and air lines was
considered difficult. Because the current technical state of the art does not provide an all-inclusive solution, no
agreement could be reached. Therefore it was agreed to publish first the general technical requirements for
the water and air lines as an International Standard. In the next step it is envisaged to find a solution for the
microbiological problems, including evaluation criteria for controlling or removing dental waterline biofilm.
