This Standard specifies requirements for filters used in eye protectors intended to provide protection against radiation of high intensity emitted during welding and allied operations. It specifies the shade numbers and the transmittance requirements of the filters, and applies to filters made of glass or other materials for absorption of radiation.
This Standard also applies to cover lenses employed for the protection of filters from damage by abrasion and weld spatter, and to filters incorporated in demonstration welding booths in so far as the relevant requirements of Table 2.1 and Table 2.2 are appropriate. Requirements for welding curtains and screens are covered in AS 3957/NZS 5852.
NOTE: Guidance on the selection of filters is given in Appendix A.
