BS EN 208:1999 Personal eye-protection. Eye-protectors for adjustment work on lasers and laser systems (laser adjustment eye-protectors)

BS EN 208 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 BS EN 208 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.

BS EN 208 defines requirements, test methods and marking. A guide is given in Annex B with regard to selection and use.

BS EN 208 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.

Before selecting eye-protection according to this standard a risk assessment should be undertaken.
