Personal eye-protection - Infrared filters - Transmittance requirements and recommended use

This European Standard specifies the scale numbers and transmittance requirements for filters for protection against infrared radiation.
The other applicable requirements for these types of filters and the frames/mountings to which they are intended to be fitted are given in EN 166.
Guidance on the selection and use of these filters is given in annex B.
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 by used.

Persönlicher Augenschutz - Infrarotschutzfilter - Transmissionsanforderungen und empfohlene Verwendung

Diese Europäische Norm legt Schutzstufen und Transmissionsanforderungen für Infrarotschutzfilter fest.
Weitere geltende Anforderungen für diese Filterarten und Fassungen/Tragkörper dieser Filter werden in EN 166 angegeben.
Anhang B gibt einen Leitfaden für die Auswahl und Anwendung dieser Filter.
ANMERKUNG      Die in dieser Norm festgelegten Schutzfilter sind nicht brauchbar für direkte oder indirekte Beobachtung von elektrischen Lichtbögen. Für diese Zwecke sollte ein für die Lichtquelle geeignetes Schweißerschutzfilter verwendet werden.

Protection individuelle de l'oeil - Filtres pour l'infrarouge - Exigences relatives au facteur de transmission et utilisation recommandée

La présente Norme européenne spécifie les numéros d'échelon et les exigences relatives au facteur de transmission des filtres de protection contre le rayonnement infrarouge. Les autres exigences applicables pour ce type de filtres figurent dans l'EN 166:1995. Un guide pour le choix et l'utilisation de ces filtres est donné en Annexe A.
