FRAME MARKING
Frame marking must include the EC Symbol and the manufacturer's identification (logo or brand).
If spectacles refer to the EN Standard, the number of the EN Standard is compulsory with the various application and mechanical strength symbols, in accordance with the tests requested by the manufacturer.
APPLICATION symbols :
3 Liquid droplets or splashes.
4 Large dust particles > 5 microns.
5 Gases and small dust particles < 5microns.
8 Short circuit electric arc.
9 Molten metal and hot solids.
MECHANICAL STRENGTH symbols :
S Extra strong, resists a 22 mm 43 g ball falling 1.30 m
F Low energy impact, resists a 6 mm 0.86 g ball at 45 m/s
B Medium energy impact, resists a 6 mm 0.86 g ball at 120 m/s
A High energy impact, resists a 6 mm 0.86 g ball at 190 m/s
MARKING OF LENSES
Marking of lenses must include:
The echelon grating for filtering lenses
The manufacturer's identification (logo or brand)
The optical class
The various mechanical strength symbols, in accordance with the tests requested by the manufacturer
The various application symbols, in accordance with the tests requested by the manufacturer.
Symbols for the OPTICAL CLASS:
1 Continuous work
2 Intermittent work
3 Occasional work, but must not be worn continuously.
MECHANICAL STRENGTH symbols :
S Extra strong, resists a 22 mm 43 g ball falling 1.30 m
F Low energy impact, resists a 6 mm 0.86 g ball at 45 m/s
B Medium energy impact, resists a 6 mm 0.86 g ball at 120 m/s
A High energy impact, resists a 6 mm 0.86 g ball at 190 m/s
K Resistance to surface deterioration by small particles (optional)
N Resistance to misting (optional)
T The letter T immediately after the impact letter allows a use for high speed particles at extremes of temperatures.
APPLICATION symbols :
9 Molten metal and hot solids.
WARNING:
F Maximum protection for spectacles with side arms
B Maximum protection for goggles
A Maximum protection for face shields
If the S,F,B and A symbols are not the same for the lens and for the frame, the lower level must be assigned to the complete protective equipment.
