This document 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 provide protection against harmful levels of optical radiation and spatter for workers who are in the vicinity of arc welding processes but not involved in the welding itself. They are intended to reduce the discomfort glare from the arc but also allow sufficient luminous transmittance to permit a view into the workspace behind. The transparent welding curtains can also be used in other applications as long as the UV- and blue-light emissions are less than in arc welding and the transmitted infrared irradiance is below applicable exposure limits. 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 document are not intended to replace welding filters. For intentional viewing of welding arcs, other means of protection are used, see ISO 16321-1 and ISO 16321-2. This document is not applicable to protection against laser radiation, for which ISO 19818-1 applies.
Abstract
Overview
ISO 25980:2023 specifies safety requirements and test methods for transparent welding curtains, strips and screens used around arc welding operations. The standard is intended to protect bystanders and nearby workers from harmful optical radiation (UV, blue light) and spatter, while still allowing visual access to the workspace. These products are designed for use at distances of at least 1 m from the arc and are not a substitute for welding filters used for intentional viewing.
Key topics and technical requirements
- Transmittance limits
- Effective ultraviolet transmittance (τUV): less than 0.002 % (200–400 nm).
- Effective blue‑light transmittance (τB): less than 1.0 % (300–700 nm).
- Luminous transmittance (τV, D65): classified into grades
- Light: 29.0–100 %
- Medium: 8.5–29.0 %
- Dark: 1.0–8.5 %
- Extra dark: 0.02–1.0 %
- Resistance to UV degradation
- Material must retain spectral protection after xenon‑arc exposure and show ≤ ±20 % relative change in luminous transmittance.
- Flame spread and fire performance
- When tested, flames must not reach the test mark, must self‑extinguish after burner removal, and not continue to glow for >3.0 s.
- Mechanical integrity
- Seams and eyelets (for curtains
