This European Standard specifies functional requirements and a product labelling applicable to temporary and
permanent passive guards (in the following called screens) for protection against laser radiation. This
standard includes test methods for testing functional performance and the specification of the user
documentation to be supplied with the product. The screens are designed to protect the user from:
? unintentional exposure to direct and/or diffuse laser radiation;
? a time limited exposure to laser radiation, based on the functional requirements determined by risk
assessment.
This European Standard applies to supervised screens for installations in working places at which laser
radiation up to a maximum mean power of 100 W or single pulse energy of 30 J occurs within the spectral
range between 180 nm (0,18 μm) and 106 nm (1 000 μm).
This European Standard applies to the protection against laser radiation only. This standard does not apply to
other hazards including hazards from secondary radiation that can arise during, for example, material
processing.
This European Standard gives guidance on how to select such screens.
Laser enclosures and housings that are supplied as part of the laser product or are supplied to be fitted to a
laser system to form a laser product (according to EN 60825-1) are not considered to be within the scope of
the standard.
