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 3.
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 International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 11810 was prepared by Technical Committee ISO/TC 172, Optics and optical instruments, Subcommittee
SC 9, Electro-optical systems.

ISO 11810:2002(E)
Introduction
Only a small number of laser applications in medicine require laser-resistant surgical drapes and/or other
patient-protective covers. Surgical drapes and/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 and/or other patient-protective covers are not necessarily
laser-resistant, specifically designed drapes offer the possibility of laser-resistance.
Laser-induced risks include ignition, flammability, 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. fiberoptic illumination systems, electrosurgical units,
hot wire cauteries, etc., this test method addresses only the laser ignition source. While it may not be necessary for
all materials used in combination with laser equipment to possess laser-resistance, a surgical drape or other
patient-protective cover that claims to be laser-resistant must be tested according to this International Standard.
CO lasers may provide the most challenging conditions of all medical lasers, but this is not certain.
2
Ignition/flammability tests, and penetration tests may disclose more challenging laser wavelengths, as well as
modes of laser delivery, for example Q-switching in the nanosecond range. Nevertheless, the 20 W CO laser
2
(continuous wave) has been selected as the default laser for this International Standard. The structure of this
International Standard is sufficiently general so that it can be performed using other wavelengths, power settings
and modes of delivery. When a CO laser is used in testing under this International Standard, in no case should it
2
have a power level less than 20 W. Users of this test method are cautioned that the laser-resistance of a surgical
drape and/or other patient-protective cover will be wavelength sensitive and that a surgical drape and/or other
patient-protective cover shall be tested at the wavelength for which it is intended. If used, those other wavelengths,
power settings and modes of delivery need to be explicitly stated.

INTERNATIONAL STANDARD ISO 11810:2002(E)

Optics and optical instruments — Lasers and laser-related
equipment — Test method for the laser-resistance of surgical
drapes and/or patient-protective covers
1 Scope
This International Standard specifies a standardized method for testing and classifying surgical drapes and other
patient-protective covers with respect to laser-induced hazards. It applies to disposable and reusable, as well as
woven and non-woven materials used as surgical drapes and other patient-protective covers which claim to be
laser-resistant. An appropriate classification system is given.
It is not the purpose of this International Standard to serve as a general fire safety specification and, as such, it
does not cover other sources of ignition nor does it cover the issue of laser-induced secondary ignition.
All materials reflect portions of the beam and it is necessary for the user to decide whether specular reflectance
may be a hazard. This measurement, however, is not covered in this International Standard.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
publications do not apply. However, parties to agreements based on this International
