Optics and optical instruments - Lasers and laser-related equipment - Determination of laser resistance of tracheal tube shafts (ISO 11990:2003)
ISO 11990:2003 specifies a method of testing the continuous wave (cw) laser resistance of the shaft of a tracheal tube. Other components of the system, such as the inflation system and cuff, are outside the scope of ISO 11990:2003.
The specified test method shall be used to measure and describe the properties of materials, products or assemblies in response to heat and flame under controlled laboratory conditions and shall not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all the factors which are pertinent to an assessment of the hazard of a particular end use. Caution should be observed in interpreting these results, since the direct applicability of the result of this test method to the clinical situation has not been fully established.
Optik und optische Instrumente - Laser und Laseranlagen - Bestimmung der Laserresistenz des Schafts von Trachealtuben (ISO 11990:2003)
Diese Internationale Norm legt ein Verfahren zur Prüfung der Laserresistenz des Schaftes eines Trachealtubus mit Dauerstrichlaser (cw) fest. Andere Komponenten des Systems, wie das Aufblassystem und die Manschette, gehören nicht zum Anwendungsbereich dieser Internationalen Norm.
Das angegebene Prüfverfahren muss angewendet werden, um die Eigenschaften der Materialien, Produkte und Zusammenbauten infolge der Einwirkung von Hitze und Flammen unter kontrollierten Laborbedingungen zu beschreiben. Es muss nicht angewendet werden, um die Feuergefahr oder das Brandrisiko von Materialien, Produkten und Zusammenbauten unter wirklichen Brandbedingungen zu beschreiben oder zu beurteilen. Jedoch dürfen Ergebnisse dieser Prüfung im Rahmen einer Brandrisikobetrachtung verwendet werden, die all jene Faktoren einbezieht, die zur Gefährdungsbestimmung eines besonderen Endzwecks dazugehören. Diese Ergebnisse sollten mit Vorsicht interpretiert werden, da die unmittelbare Anwendbarkeit des Ergebnisses dieses Prüfverfahrens auf die klinische Situation nicht umfassend abgesichert ist.
ANMERKUNG Dieses Prüfverfahren kann die Anwendung von gefährlichen Materialien, Handhabungen und Ausrüstungsgegenständen beinhalten. Diese Internationale Norm hat nicht den Anspruch, alle Sicherheitsprobleme anzusprechen, die sich bei ihrer Anwendung ergeben. Es liegt in der Verantwortung des Anwenders dieses Prüfverfahrens, die passenden Praktiken bezüglich Sicherheit und Gesundheit festzulegen sowie vor der Anwendung zu bestimmen, welche gesetzlichen Beschränkungen zu beachten sind.
Optique et instruments d'optique - Lasers et équipements associés aux lasers - Détermination de la résistance au laser des tubes trachéaux (ISO 11990:2003)
L'ISO 11990:2003 spécifie une méthode d'essai de la résistance à un laser fonctionnant en régime continu du tube proprement dit d'un tube trachéal. Les autres éléments du système, comme le système de gonflage et le ballonnet, n'entrent pas dans le domaine d'application de la présente Norme internationale.
La méthode d'essai spécifiée sera utilisée pour mesurer et décrire les propriétés des matériaux, produits ou assemblages par rapport à la chaleur et à la flamme, en conditions de laboratoire contrôlées, et non pour décrire ou évaluer le danger ou le risque de feu pour les matériaux, produits ou assemblages en conditions réelles de feu. Cependant, les résultats de cet essai peuvent constituer des éléments d'évaluation du risque de feu prenant en compte tous les facteurs pertinents pour l'évaluation du danger dans le cadre d'un usage particulier. Il convient d'interpréter ces résultats avec prudence, car l'applicabilité directe du résultat de cette méthode d'essai à la situation clinique n'a pas été complètement établie.

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 11990 was prepared by Technical Committee ISO/TC 172, Optics and optical instruments, Subcommittee
SC 9, Electro-optical systems.
This second edition cancels and replaces the first edition (ISO 11990:1999), Clause 12 of which has been
technically revised.

ISO 11990:2003(E)
Introduction
Surgery in the airway in which a laser is used brings together an oxygen-enriched atmosphere, fuel and high
energy that can combine to create a fire. In the early to middle 1980s, the increasing use of such lasers was
followed by airway fires and the subsequent development of tracheal tubes designed specifically to be resistant
to laser ignition and damage. Unfortunately, some of these tubes were not sufficiently resistant under operating
room conditions, and airway fires continued to occur. These events lead to the development of the test method
described in this International Standard, in order to assist the clinician in determining which tracheal tube shaft
is most laser-resistant for a defined set of conditions.
