Guaranteed minimum resistance of the protective eyewear against everyday risks including dropping the protective eyewear onto the ground, ageing by light exposure, exposure to heat or corrosion etc.
Risks relating to radiations - UV Protection - EN170
The protection filters ultraviolet radiation. This type of protection is particularly recommended during activities where the source of ultraviolet radiation is predominant, such as mercury vapor lamps, actinic or germicides. Levels of application: 2-1.2, 2C-1.2 Lens color: Clear, blue, yellow or green. Adding the code "C" indicates good color recognition by the holder
Solar radiations risks - EN172
Filter protection for industrial solar radiation. Recommended for outdoor work, EN172 norm guarantee a protection of 99.99% from ultra-violet solar radiation. Levels of application: 5-3.1 (Polarized) 5-2 (Twilight), 5-1.4 (ESP or CSP), 5/1.1-1.4 (Contrast), 5-2.5 and 5 to 4.1 (smoke) Lens colour: depends on the lens technology
European standard - CE
Frame marking must include the CE symbol
Chemical risk - 3
Chemical protection against liquid droplets or splashes. Goggles, adapted spectacles with strap or face shield mandatory.
Chemical risk - 4
Chemical protection against gas and fine dust particles < 5 microns (sealed goggle mandatory)
Mechanical risk - Low energy impact - F
Low energy impact, resists a 6 mm, 0.86 g ball at 45 m/s
Mechanical risk- Medium energy impact - B
Medium energy impact, resists a 6 mm, 0.86 g ball at 120 m/s
Mechanical risk- High speed particles at extreme temperatures - T
The letter T, immediately after the mechanical strength symbol, authorises use for high speed particles at extreme temperatures.
Optical class - 1
Continuous work - Worn permanently
