Lasers and laser-related equipment - Test method and classification for the laser-resistance of surgical drapes and/or patient-protective covers - Part 2: Secondary ignition (ISO 11810-2:2007)
This part of ISO 11810 is applicable to disposable and re-usable, as well as woven and non-woven materials used as surgical drapes and/or patient protective covers which claim to be laser-resistant. The purpose of this part of ISO 11810 is to provide a standardized method for testing and classifying surgical drapes and/or patient protective covers with respect to laser-induced hazards. An appropriate classification system is given. It is not the purpose of this part of ISO 11810 to serve as a general fire safety specification. This part of ISO 11810 is limited to testing the secondary ignition of materials that are rated 1 or 2 from ISO 11810-1. All materials reflect portions of the beam and it is necessary for the user to decide whether specular reflection may be a hazard. This measurement, however, is not covered in this part of ISO 11810. The results of this part of ISO 11810 are not to be applied to other wavelengths and temporal formats.
Laser und Laseranlagen - Prüfverfahren und Einstufung zur Laserresistenz von Operationstüchern und/oder anderen Abdeckungen zum Schutz des Patienten - Teil 2: Sekundäre Entzündung (ISO 11810-2:2007)
Dieser Teil von ISO 11810 gilt für Einwegprodukte und wieder verwendbare gewebte Materialien und Vliesstoffe, die als Operationstücher und andere Abdeckungen zum Schutz des Patienten mit dem Anspruch auf Laserstrahlungsbeständigkeit verwendet werden.
Der Zweck dieses Teils von ISO 11810 ist, ein genormtes Verfahren zur Prüfung und Einstufung von Operationsabdecktüchern und anderen Abdeckungen zum Schutz des Patienten hinsichtlich der durch Laser hervorgerufenen Gefährdungen zur Verfügung zu stellen. Ein geeignetes Einstufungssystem wird angegeben. Der Zweck dieses Teils von ISO 11810 besteht nicht darin, als allgemeine Brandsicherheitsvorschrift zu dienen. Dieser Teil von ISO 11810 beschränkt sich darauf, ein Verfahren zur Prüfung der sekundären Entzündung für Materialien festzulegen, die nach ISO 11810 1 mit I1 oder I2 bewertet wurden.
Alle Materialien reflektieren Anteile des Strahls, und es ist für den Anwender erforderlich, entscheiden zu können, ob die spiegelnde Reflexion eine Gefährdung darstellen kann. Diese Messungen werden jedoch in diesem Teil von ISO 11810 nicht erfasst.
Prüfergebnisse nach diesem Teil von ISO 11810 sollten nicht auf andere Wellenlängen und Zeitverhaltensweisen angewendet werden.
ANMERKUNG Für diesen Teil von ISO 11810 wurde der 20 W CO2 Laser (Dauerstrich) ausgewählt. Die Anwender der nach diesem Verfahren geprüften Produkte werden warnend darauf hingewiesen, dass die Laserstrahlungsbeständigkeit eines Operationstuches und/oder einer anderen Abdeckung zum Schutz des Patienten von der Wellenlänge abhängt und dass das Tuch und/oder die Abdeckung bei der Wellenlänge geprüft werden sollte, für die ihr Einsatz vorgesehen ist. Bei Prüfung unter Anwendung anderer Wellenlängen müssen die Leistungswerte und Anregungsarten explizit angegeben werden.

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 11810-2 was prepared by Technical Committee ISO/TC 172, Optics and photonics, Subcommittee SC 9,
Electro-optical systems.
ISO 11810 consists of the following parts, under the general title Lasers and laser-related equipment — Test
method and classification for the laser-resistance of surgical drapes and/or patient-protective covers:
⎯ Part 1: Primary ignition and penetration
⎯ Part 2: Secondary ignition
For the purposes of this part of ISO 11810 the CEN annex regarding fulfilment of European Council Directives
will be removed at publication stage.

ISO 11810-2:2007(E)
Introduction
Some laser applications in medicine may require laser-resistant surgical drapes or other patient protective
covers. Surgical drapes or other patient protective covers are necessary when a sterile procedure is
performed and the surrounding area needs to be protected from liquids, secretions and inadvertent laser
radiation. While conventional surgical drapes or other patient protective covers are not necessarily laser-
resistant, specifically designed drapes offer the possibility of laser resistance.
Laser-induced risks include ignition, inflammability, melting, penetration, thermal transfer and reflectivity.
Textile and non-woven drape materials may have other risks but they may provide a laser barrier. While there
are many potential ignition devices present in the operating room, e.g. fibre optic illumination systems, electro-
surgical units, hot wire cauteries, etc., this test method addresses only the laser ignition source. A surgical
drape or other patient protective cover that claims to be laser-resistant must be tested according to this part of
ISO 11810.
CO lasers may provide the most challenging conditions of all medical lasers. Ignition/inflammability tests and
2
penetration tests may disclose more challenging laser wavelengths as well as modes of laser delivery, for
example Q-switching in the nanosecond range. The 20 W CO laser (continuous wave) has been selected as
2
the laser to be used for this part of ISO 11810. For laser-induced secondary ignition of drapes and/or patient
protective covers, the risk is dependent on spot size at a given power setting. In addition, areas within a given
product may vary in material composition or design. Depending on the claims being made by the
manufacturer or end-user requirements, all areas within the product may need to be tested.
This part of ISO 11810 applies to secondary ignition and is provided with information additional to
ISO 11810-1 for testing and reporting test results. The purpose of secondary ignition is to simulate a situation
where a surgical drape or other protective cover is placed over another material. A piece of cotton gauze is
used to simulate this other material. This part of ISO 11810 determines whether ignition of the cotton gauze
will ignite the surgical drape and/or patient protective cover and whether the surgical drape and/or patient
protective cover will continue to burn once the burning cotton has been removed. The afterflame of the
surgical drape and/or protective cover is also determined.
The performance of laser resistant surgical drapes or other patient covers may be degraded when used in
combination rather than individually.
