Personal eye-protection - Ultraviolet filters - Transmittance requirements and recommended use
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.
Persönlicher Augenschutz - Ultraviolettschutzfilter - Transmissionsanforderungen und empfohlene Anwendung
Die vorliegende Europäische Norm legt Schutzstufen und Transmissionsanforderungen für Schutzfilter gegen Ultraviolettstrahlung fest.
Die weiteren geltenden Anforderungen für diese Filterarten und die Anforderungen für die Tragkörper/Rahmen, in die sie eingebaut werden sollen, sind in EN 166 angegeben.
Anhang B gibt einen Leitfaden für die Auswahl und Anwendung dieser Filter.
ANMERKUNG Die in dieser Norm behandelten Schutzfilter sind nicht für das direkte Sehen in helle Lichtquellen wie Xenon-Hochdruckbogenlampen oder für die direkte oder indirekte Beobachtung eines Lichtbogens geeignet. Für diese Zwecke sollte ein Schweißerschutzfilter nach EN 169 mit einer entsprechenden Schutzstufe angewendet werden, das für die beobachtete Lichtquelle geeignet ist.
Protection individuelle de l'oeil - Filtres pour l'ultraviolet - 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 ultraviolet.
Les autres exigences applicables pour ces types de filtres et les montures/supports sur lesquels ils doivent etre montés figurent dans l'EN 166.
Un guide pour le choix et l'utilisation de ces filtres est donné a l'annexe B.
NOTE Les filtres de protection spécifiés dans la présente norme ne conviennent pas pour l'observation directe de sources lumineuses vives telles que les lampes a arc de xénon a haute pression ou pour l'observation directe ou indirecte d'un arc de soudage électrique. Dans ce cas, il convient d'utiliser un filtre de soudage tel que spécifié dans l'EN 169, ayant un numéro d'échelon approprié a la source observée.

EN 170:2002 (E)3ForewordThis document (EN 170:2002) has been prepared by Technical Committee CEN /TC 85, "Eye-protectiveequipment", the secretariat of which is held by AFNOR.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by April 2003, and conflicting national standards shall be withdrawn at the latest byApril 2003.This document supersedes EN 170:1992.This document has been prepared under a mandate given to CEN by the European Commission and the EuropeanFree Trade Association, and supports essential requirements of EU Directive(s).For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document.In this European Standard, Annex A is normative and Annexes B and C are informative.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,Sweden, Switzerland and the United Kingdom.
EN 170:2002 (E)41 ScopeThis European Standard specifies the scale numbers and transmittance requirements for filters for protectionagainst ultraviolet radiation.The other applicable requirements for these types of filters and the frames/mountings to which they are intended tobe fitted are given in EN 166.Guidance on the selection and use of these filters are given in annex B.NOTEThe protective filters specified in this standard are not suitable for the direct viewing of bright light sources likeXenon high-pressure arc lamps or for the direct or indirect observation of an electric welding arc.
