Bibliography
This European Standard specifies the scale numbers and transmittance requirements for filters for protection against ultraviolet radiation. The other applicable requirements for these types of filters are given in EN 166:1995. Guidance on the selection and use of these filters are given in Annex A. NOTE: The protective filters specified in this standard are not suitable for the direct or indirect observation of an electric arc. For this purpose a welding filter appropriate to the source being observed should be used. Such a filter would not have a scale number less than 6.
