28、ork 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-govern

29、mental, 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.The procedures used to develop this document and those intended for its further maintenance are described in t

30、he ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the poss

Surgical d

35、rapes 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-resist

36、ant, specifically designed surgical 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 can have other risks but they can provide a laser barrier. While the

37、re are many potential ignition devices present in the operating room (e.g. fibre optic illumination systems, electro-surgical units, hot wire cauteries), this test method addresses only the laser ignition source. This International Standard is intended for use in testing a surgical drape or other pa

38、tient-protective cover that claims to be laser-resistant. In addition, areas within this product can vary in material composition or design. Depending on the claims being made by the manufacturer or end-user requirements, all areas for which laser resistance is claimed might need to be tested.CO2las

39、ers can induce the most challenging conditions of all medical lasers. Ignition/flammability tests and penetration tests can reveal more challenging laser wavelengths as well as modes of laser delivery, for example Q-switching in the nanosecond range. The 20 W CO2laser (continuous wave) has been sele

40、cted as the laser for this International Standard.Users of this test method are cautioned that the laser resistance of a surgical drape or other patient-protective cover will be wavelength sensitive and that a surgical drape or other patient-protective cover should be tested at the wavelengths for w

41、hich it is intended to be used. If tested using other wavelengths, it is necessary to explicitly state the power settings and modes of delivery.The results from this International Standard should not be applied to other wavelengths and temporal formats.The performance of laser-resistant surgical dra

42、pes or other patient-protective covers can be changed when used in combination rather than individually.

43、protective covers Primary ignition, penetration, flame spread and secondary ignitionCAUTION This test method can involve hazardous materials, operations and equipment. This International Standard provides advice on minimizing some of the risks associated with its use but does not purport to address

44、all such risks. It is the responsibility of the user of this International Standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.1 ScopeThis International Standard is applicable to disposable and reusable, as well as w

45、oven and non-woven materials used as surgical drapes and other patient-protective covers which claim to be laser-resistant. The purpose of this International Standard is to provide a standardized method for testing and classifying surgical drapes and other patient-protective covers with respect to l

46、aser-induced hazards. 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, this International Standard does not cover other sources of ignition.All materials reflect portions of the beam and

47、it is necessary for the user to decide whether specular reflectance can be a hazard. This measurement, however, is not covered in this International Standard.The test procedure can be used to assess the laser induced flammability properties of non-laser-resistant itemsNOTE Users of products tested b

48、y this method are cautioned that the laser resistance of a surgical drape and/or patient-protective cover will be wavelength sensitive and that a surgical drape and/or patient-protective cover are better tested at the wavelength for which it is intended to be used. If tested using other wavelengths,

49、 it is necessary to explicitly state the power settings and modes of delivery.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
