NBN EN ISO 11810-2:2007

This International Standard 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.
The purpose of this standard is to provide a standardized method for testing and classifying surgical drapes and other patient protective covers with respect to laser-induced hazards. An appropriate classification system is given. It is not the purpose of this standard to serve as a general fire safety specification. This standard is limited to testing the secondary ignition of materials that are rated I1 or I2 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 standard.
