Purpose.

The purpose of this standard is to provide reasonable and adequate means, ways and methods for the testing, selection and safe use of transparent welding curtains and screens.

In order to carry this out, the function of these transparent welding curtains and screens needs to be understood clearly.

These devices are designed to provide outside viewers, at some distance from the welding arc or operation, a safe view of the operation and operator.

Transparent welding curtains and screens are not meant to replace a welding filter plate or to provide a close-up view of the welding operation.

Transparent welding curtains or screens are intended to be used at least 1 meter from the arc or operation.

In establishing safety requirements, the hazards for a viewer at least 1 meter away were considered, with an 8-hour viewing time.
