適用范圍：This European Standard specifies functional requirements and a product labelling applicable to temporary andpermanent passive guards (in the following called screens) for protection against laser radiation. Thisstandard includes test methods for testing functional performance and the specification of the userdocumentation 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 riskassessment.This European Standard applies to supervised screens for installations in working places at which laserradiation up to a maximum mean power of 100 W or single pulse energy of 30 J occurs within the spectralrange 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 toother hazards including hazards from secondary radiation that can arise during, for example, materialprocessing.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 alaser system to form a laser product (according to EN 60825-1) are not considered to be within the scope ofthe standard.
