EN 169:2002 (E)3ForewordThis document (EN 169:2002) 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of an identical text orby endorsement, at the latest by May 2003, and conflicting national standards shall be withdrawn at the latest byMay 2003.This document has been prepared under a mandate given to CEN by the European Commission and the EuropeanFree Trade Association, and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.The annexes A and C are informative.

Annex B is normative.In the revision of this European Standard, and that of EN 379, which was performed concurrently, it was decided toremove from EN 379 welding filters with dual scale numbers and include them within this European Standard.This document supersedes EN 169:1992.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland,Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the UnitedKingdom.

The light zone is used for brief viewing when setting the electrode to the weld and igniting it. Thedark zone is used for viewing the welding process4 Designation and identificationThe complete table of numbering of filters is given in EN 166.The marking of oculars and frame is described in EN 166.The scale number of these filters comprises only the shade number corresponding to the filter, from 1,2 to 16(see Table 1).

EN 169:2002 (E)55 Requirements5.1 GeneralThe requirements of EN 166 apply to welding filters. Only those requirements that are different from or supplementthe EN 166 specifications are given in this European Standard.5.2 Transmittance requirementsThe definitions of transmittances are given in EN 165.The determination of luminous transmittance is described in EN 167.The transmittance requirements for filters used in welding and related techniques are given in Table 1.Table 1 – Transmittance requirementsMaximumspectral transmittancein the ultraviolet()LuminoustransmittancevMaximum meanspectral transmittanceinthe infraredAScale number313 nm%365 nm%Maximum%Minimum%780 nm to 1 400 nm%1,20,00035010074,4691,40,00033574,458,1521,70,00032258,143,24020,00031443,229,1282,50,00036,429,117,81530,00032,817,88,51240,00030,958,53,26,450,00030,303,21,23,260,00030,101,20,441,770,00030,0500,440,160,8180,00030,0250,160,0610,4390,00030,0120,0610,0230,20100,00030,0060,0230,00850,10110,00030,00320,00850,00320,050120,00030,00120,00320,00120,027130,00030,000440,00120,000440,014140,000160,000160,000440,000160,007150,0000610,0000610,000160,0000610,003160,0000230,0000230,0000610,0000230,003Minimum and maximum values of luminous transmittance may be exceeded by taking into account the limits of“relative uncertainty” given in EN 167.
