EVS-EN 12254:1999+A2:2008

This standard specifies functional requirements and a product labelling system applicable to a range of temporary and permanent passive guards 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.
