(1) The basic requirement
specified in EN 166 : 1995 clause 7.1 must be satisfied for basic usage and
for all other applications |
| (2)
If the S, F, B and A symbols are not the same for the lens and the frame,
then the lowest level should be assigned to the complete eye protection. |
| EN
166 2001: the letter T immediately after the impact letter allows a use for
high speed particles at extremes of temperature. |
| (3)
A face shield for usage range with symbol 8 must be fitted with a scale
number 2-1,2 or 3-1,2 and its minimum thickness must be 1.2mm. |
| (4)
For eye protection satisfying usage range symbole 9, the frame and the glass
must both be marked with this symbol and one of the symbols F, B or A. |
