PROTECTION : ASSOCIATED RISKS
Low energy impact - F
Low energy impact, resists a 6 mm, 0.86 g ball at 45 m/s this is very good safety numbers
risk- High speed particles at very high temperatures - T
The letter T, after the strength symbol, authorises the glasses for use at high speed
particles at very high temperatures.
UV Protection is EN 170 - (2-1.2, 2C-1.2)
The protection filters ultraviolet radiation and gives protection
