UNE-EN ISO 25980:2023

This International Standard specifies safety requirements for transparent welding curtains, strips, and screens to be used in workplaces where arc welding is taking place. They are intended to provideprotection of workers against harmful levels of optical radiation and spatter who are in the vicinity of arc welding processes but not involved in the welding itself. They are intended to reduce the discomfortglare from the arc but also allow sufficient luminous transmittance to permit a view into the workspace behind. The transparent welding curtains may also be used in other applications as long as the UV- andblue-light emissions are less than in arc welding. They are designed to be used at a distance from the arc of at least 1 m.Welding curtains, strips, and screens specified in this International Standard are not intended to replace welding filters. For intentional viewing of welding arcs other means of protection are used, seeISO 16321-1 and ISO 16321-2.This International Standard is not applicable for protection against laser radiation for which ISO 19818-1 applies.
