MARKING OF FRAMES (a) Manufacturer (b) EN standard number (c) Suitable areas of application No marking = basic use (glasses) 3 = liquids (goggles and visors) 4 = dust particles >μm (goggles) 5 = gas and dust particles >μm (goggles) 8 = short circuit electrical arcs (visors) 9 = molten metal and hot material (goggles and visors) (d) Mechanical resistance S = enhanced strength F = high speed, low energy impact (6mm steel ball at 45 m/s) B = high speed, medium energy impact (6mm steel ball at 120 m/s) A = high speed, high energy impact (6mm steel ball at 190 m/s) Marking “T” after the symbol for mechanical resistance indicates protection at extreme temperatures (FT, BT, AT) (e) H = suitable for a smaller head shape (f) Highest shade number compatible with that particular frame MARKING OF LENSES a) Filter type 2 or 2C = UV 4 = IR b) Shade number c) Manufacturer d) Optical class 1 = permanent use 2 = temporary use 3 = used in exceptional cases e) Mechanical resistance S = enhanced strength F = high speed, low energy impact (6mm steel ball at 45 m/s) B = high speed, medium energy impact (6mm steel ball at 120 m/s) A = high speed, high energy impact (6mm steel ball at 190 m/s) Marking “T” after the symbol for mechanical resistance indicates protection at extreme temperatures (FT, BT, AT) f) Other requirements 8 = short circuit electric arcs (visors) 9 = molten metal and hot materials (goggles and visors) 386
