EVS-EN 208:1999

This european standard applies to laser adjustment filters and eye-protectors. These are filters and eye-protectors for use in adjustment work on lasers and laser systems as defined in EN 60825-1:1994 (i.e. LED (Light Emitting Diode) radiation is included) where hazardous radiation occurs in the visible spectral range of 400 nm to 700 nm. Filters specified in this standard reduce this radiation to values defined for lasers of class 2 (< 1 mW for CW (Continuous wave) lasers). In this case aversion responses including the blink reflex contribute to eye protection.  This standard defines the requirements, test methods and marking. A guide is given in annex B with regard to selection and use.  EN 207 applies to eye-protection against laser radiation where aversion responses including the blink reflex is not stipulated and laser radiation outside the visible spectral range.  NOTE: Before selecting eye protection according to this standard a risk assessment should first be undertaken (see annex B).
