DIN EN ISO 11810-2-2009 激光和相关的激光设备.手术单和/或病患者护罩耐激光性的试验方法和分类.第2部分:次级点火(ISO 11810-2:2007),英文版本DIN EN ISO 11810-2:2009-07
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); English version of DIN EN ISO 11810-2:2009-07
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 I1 or 12 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.
The 20 W CO2 laser (continuous wave) has been selected as the laser to be used for this part of ISO 11810.
NOTE Users of products tested by 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, the power settings and modes of delivery need to be explicitly stated.
