This standard shall apply to transparent welding curtains and screens used for all welding and cutting operations or processes where harmful sparks, spatter, and radiation are emitted, and excludes those sources that emit x-rays, gamma rays, particulate radiation (such as alpha and beta radiation), laser light, or electron beams. This standard informs the reader of reasonable and adequate means, ways, and methods for the testing, selection, and safe use of transparent welding curtains and screens. 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.
