- Part 2: Specifications for progressivepower lenses (ISO 8980-2:1996).EN ISO 8980-3, Ophtalmic optics – Uncut finished spectacle lenses – Part 3 : Transmittance specifications and testmethods ( ISO 8980-3 :1999).3 Terms and definitionsFor the purpose of this European Standard, the terms and definitions given in EN 165 and the following apply.3.1visual centrethe point on the ocular corresponding to the intersection of the horizontal and vertical planes through the pupil ofthe appropriate head-form specified in clause 17 of EN 168:2001 when the eye-protector is fitted to it in accordancewith the manufacturers instructions4 Classification4.1 Function of eye-protectorsThe function of eye-protectors is to provide protection against: impacts of different severities; optical radiations; molten metals and hot solids; droplets and splashes; dust; gases; short circuit electric arc;or any combination of these.4.2 Types of eye-protectorsNOTERefer to definitions given in EN 165.4.2.1 Spectacles with or without lateral protection4.2.2 Goggles4.2.3 Face-shieldsNOTEFace-shields normally incorporate a suitable headband, browguard, helmet, protective hood or other appropriatemounting device.

10°.7.1.2.1.3 Cover platesThe refractive powers of cover plates shall comply with the tolerances for optical class 1 given in Tables 2 and 3.7.1.2.2 Transmittance7.1.2.2.1 Oculars without filtering actionOculars intended to protect the eyes against mechanical or chemical hazards only, and cover plates, shall have aluminous transmittance greater than 74,4 % when measured as given in clause 6 of EN 167:2001 (based on CIEsource A (2856 K)).7.1.2.2.2 Oculars with filtering action (filters) and housings for oculars with filtering action.The transmittance of oculars with filtering action shall meet the requirements given in the specific standards relatingto the various types of ocular (see 7.2.1).Goggles and face-shields which claim to provide protection against optical radiation shall provide at least the samelevel of protection against optical radiation as given by a filter of any scale number declared usable with the eye-protector by the manufacturer or supplier. Testing shall be in accordance with clause 6 of EN 167:2001.7.1.2.2.3 Variations in transmittance (Oculars without filtering action are exempt from this requirement)7.1.2.2.3.1 Oculars without corrective effectVariations in luminous transmittance shall be measured in accordance with clause 7 of EN 167:2001.The relative variations of the luminous transmittance around the visual centre(s) P1 (and P2) shall not exceed thevalues of Table 4.The relative difference in luminous transmittance P3 between left and right eye shall not exceed the values ofTable 4 or 20 % whichever is greater.

The exemption does not apply to coated or laminatedglass.7.1.5.1 Stability at an elevated temperatureAssembled eye-protectors shall show no apparent deformation when tested by the method specified in clause 5 ofEN 168:2001.7.1.5.2 Resistance to ultraviolet radiation (oculars only)Oculars shall be subjected to the test for resistance to ultraviolet radiation in accordance with the method specifiedin clause 6 of EN 168:2001.At the end of the test, oculars shall meet the following requirements.a) The relative change of luminous transmittance shall not be greater than the values specified in Table 6.If for welding filters the relative change of the luminous transmittance is larger than the values specified inTable 6 but the actual value of luminous transmittance remains within the range specified by its shade number,a second irradiation is performed in accordance with clause 6 of EN 168:2001
on the same sample. Therelative change of luminous transmittance due to the second irradiation shall not be greater than the valuesspecified in Table 6 and the actual value of luminous transmittance shall remain within the range specified byits shade number;b) The value of the reduced luminance factor shall not exceed the permissible limits given in 7.1.2.3.Table 6 — Permissible relative change in luminous transmittance following the ultraviolet radiation testLuminous transmittanceless thanup toPermissible relativechange%%%10017,8± 517,80,44± 100,440,023± 150,0230,0012± 200,00120,000023± 307.1.6 Resistance to corrosionAfter having undergone the test for resistance to corrosion specified in clause 8 of EN 168:2001, all metal parts ofthe eye-protector shall display smooth surfaces, free from corrosion, when they are examined by a trainedobserver.7.1.7 Resistance to ignitionEye-protectors shall be tested in accordance with the method specified in clause 7 of EN 168:2001 and shall beconsidered to be satisfactory if no part of the eye-protector ignites or continues to glow after removal of the steelrod.
