Mechanical risk - Low energy impact. Low energy impact, resists a 6 mm, 0.86 g ball at 45 m/s.
Mechanical risk- High speed particles at extreme temperatures. The letter T, immediately after the mechanical strength symbol, authorises use for high speed particles at extreme temperatures.
Resistance to surface damage by fine particles - The anti-scratchcoating K provides enhanced scratch-certified coating.Resistance to fogging - The anti-fog coating N is an anti-fog treatment certified.Optical class - Continuous work - Worn permanently.
