d) lateral protection failure the lateral pI’otection shall be considered to have failed if it fractures through its entire thickness into two or more separate pieces, or if one or more particles become detached from the surface remote from the impact point, or if it allows the ball to penetrate completely, or it it partially or totally detaches from the eye-protector, or if its component parts become separated.
71.5 Resistance to ogeing
NOTE Cover plates and glass oculars are exempt from these tests. The exemption does not apply to coated or Iwnated glass.
7.1,5.1 StabIlity at an elevated temperature
Assembled eye-protectors shall show no apparent deformation when tested by the method specified in clause 5 of EN 168:2001.
7.1.5.2 Resistance to ultraviolet radiation (oculars only)
Oculars shall be sublected to the test for resistance to ultraviolet radiation in accordance with the method specified in 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 in Table 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. The relative change of luminous transmittance due to the second irradiation shall not be greater than the values speofied in Table 6 and the actual value of luminous transmittance shall remain within the range specified by its shade number;
b) The value of the reduced luminance factor shaM not exceed the permissible limits given in 7.1.2.3,
a) the eye-protector is either a goggle or a face-shield;
b) the viewing area of oculars for face-shields has a minimum vertical centre-line depth of 150 mm when mounted in the appropriate housing:
C) face-shields cover the eye-region rectangle 01 the appropriate head-form as assessed i accordance with 10.2 of EN 1682001;
d) the eye-protector satisfies the requirements for one of me three impact energy categories given in 7.2,2;
e) when tested and assessed in accordance with 10.1 of EN 168:2001 they prevent the adherence of molten metal to the portion of me eye-protector which affords protection to the eye-region rectangle ABCD shown ii Figure 11 01 EN 168:2001;
I) complete penetration of oculars for goggles, and all types of frames. housings, owguards, etc. does not occur within 7 s when tested as described in clause 11 of EN 168:2001:
g) complete penetration of oculars for lace-stiields does not occur within 5s when tested as described ii clause 11 of EN 168-2001.
7.2.4 Protection agaInst droplets and splashes of lIquIds
Eye-protectors for use against droplets (goggles) and sptashes of liquids (face-shields) shall be tested in accordance with the methods specihed in clause 12 of EN 168:2001, The results shall be considered to be satisfactory if:
a) no pink or crimson colouration appears in the ocular regions delined by the two circles when assessing goggles for protection against droplets. No account shall be taken of any such colouration to a distance of 6 mm inside the edges of the eye-protector:
b) face-shields cover the eye-region rectangle of the appropriate head-form as described in 10.2.2.2 of EN 168:2001 as assessed in accordance with 10.201 EN 1682001.
Additionally, face-shields for protection against splashes of liquids shall have a viewing area with a mirmum vertical centre-line depth oft 50 mm when mounted in the appropriate housing.
7.2.5 ProtectIon against larg. dust particles
Eye-protectors for use against large dust particles shall be tested in accordance with the method specified in clause 13 of EN 168:2001. The result shall be considered to be satisfactory if the reflectance after the test is not less than 80% of its value before the test.
7.2.6 Protection against gases and fine dust particles
Eye-protectors for use against gases and fine dust particles shall be tested In accordance with the method specified In clause 14 of EN 1682001. They shall be regarded as satisfactory ii no pink or crimson coloration appears t the area covered by the eye-protector. No account shall be laken of any such coloration up to a distance of 6 mm inside the edges of the eye-protector.
7.2.7 Protection against short circuit electric arc
Eye-protectors for protection against short circuit electric arc shall be face-shields only. They shall have no exposed metal parts and all external edges of the protector shall be radiussed, chamfered or otherwise treated to eliminate sharp edges.
Oculars shall have a minimum thickness of 1.4 mm and a scale number of 2.1 .2 or 3-1.2.
