LAHTI PRO PROLINE MEGA TRYTON VULCAN Technical informations PAGE WWW.PROFIX.COM.PL 187 Marking of safety glasses and goggles is used for their identification and correct selection for hazards at the given workplace. Protection screens (lenses) and frames (mountings) are marked separately. However if they constitute the whole, all the required marking symbols should be on a frame (mounting). • CE mark • filter type (from 2 to 6) • shade (from 1.2 to 16) • identification mark of the manufacturer • optical class (from 1 to 3) • mechanical strength symbol (“S”, “F”, “B”) • additional protection features symbol (“K”, “N”, “R”, “T”) • CE mark • identification mark of the manufacturer • standard no. • mechanical strength symbol (“S”, “F”, “B”) • additional protection features symbol (“K”, “N”, “R”, “T”) 1.2 100 – 74.4 % 1.4 74.4 – 58.1% 1.7 58.1 – 43.2% 2.0 43.2 – 29.1% 2.0 43.2 – 29.1% 2.5 29.1 – 17.8% 3.1 17.8 – 8.0% 4.1 8.0 – 3.0% ... 16 0.000061 – 0.000023% EYE AND FACE PROTECTION CLASSES – MECHANICAL INJURIES PARAMETER SAFETY GLASSES GOGGLES FACE SHIELD Increased impact resistance 5.1m/s) – mark.
