Scope

This standard specifies functional requirements and a product labelling system applicable to a range of 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 also the specification of the user documentation to be supplied with the product. The screens are designed to protect the user from uncontrolled emission of direct and/or diffuse radiation for a defined exposure to lasers, based on the necessary functional requirements for any particular application being determined by risk assessment principles. This 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 æm) and 106 nm (1000 æm). This 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 standard gives guidance on how to select such screens. The following are not considered to be within the scope of the standard: - 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 IEC 60 825-1:1998); - any screen whose protective properties are limited to a restricted range of angles of incidence (e.g. some interference filters).
