This document specifies general requirements for operators' eye protectors for intense light source (ILS) equipment used on humans and animals for cosmetic and medical applications against excessive exposure to optical radiation in the spectral range 250 nm to 3 000 nm, with the exception of laser radiation.
This document is applicable to devices intended for patient protection during ILS procedures, except for treatment in the periorbital area. For guidance on patient eye protection during ILS procedures, see ISO/TR 22463.
For guidance on the use and selection of ILS eye protectors, see ISO 12609-2.
This document does not apply to:
—    laser protectors, for which ISO 19818-1 applies;
—    protectors for medically prescribed applications (not occupational), e.g. eye protection for severe dry eye, tints prescribed for medical conditions;
—    protectors specifically intended for protection against only solar radiation and used in non-occupational environments for which the ISO 12312 (all parts) applies;
—    protectors used with tanning equipment;
—    protectors intended to protect against ionizing radiation, e.g. X-rays, for which IEC 61331-3 applies.

This European standard specifies requirements for automatic welding filters which switch their luminous transmittance to a lower predetermined value when a welding arc is ignited (referred to as welding filters with switchable scale numbers). It also specifies requirements for automatic welding filters which switch their luminous transmittance to a lower value, where the lower value of luminous transmittance is set automatically in dependence on the illuminance generated by the welding arc (referred to as welding filters with automatic scale number setting).
The requirements of this standard apply if such a filter is to be used for continuous viewing of the welding process, (including gas welding and cutting), and if it is to be used only during the period when the arc is being ignited.
These filters are used in welders' eye protectors or are fixed to equipment.
If they are to be used in welders’ eye protectors, other applicable requirements for these types of filters are given in EN 166. The requirements for the frames/mountings to which they are intended to be fitted are given in EN 175.
Guidance on the selection and use of these filters is given in annex A.
The specifications for welding filters without switchable luminous transmittance are given in EN 169.

This European standard specifies the scale numbers and transmittance requirements for filters intended to protect operators performing work involving welding, braze-welding, arc gouging and plasma jet cutting. 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. The specifications for welding filters with switchable luminous transmittance and welding filters with dual luminous transmittance are given in EN 379:1994.

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.
