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 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 are not stipulated, and laser radiation outside the visible spectral range.
NOTE Before selecting eye-protection according to this standard a risk assessment should be undertaken (see Annex B).
