The frame shall be designed so that no laser radiation can penetrate from the side. This requirement is met if for the horizontal angle range α from - 50° (nasal side) to + 90° (temporal side) the vertical angle range β is protected within the following limit angles in degrees (°). The upward limit βu of the protected range shall be: ()()46212103,1123001,055−×−−−=−ααβu (4) The downward limit βl of the protected range shall be: ()()462522103,2221070−×+−+−=−−ααβl (5) Testing shall be done in accordance with 4.10.
3.10 Mechanical strength of eye-protectors 3.10.1 Basic requirement Filters for protection against laser radiation shall satisfy the requirement for minimum robustness as specified in 7.1.4.1 of EN 166:2001. The frames of the eye-protectors shall satisfy the requirements of 7.1.4.2 or 7.2.2 of EN 166:2001. 3.10.2 Optional requirements If the mechanical strength of filters and eye-protectors against laser radiation is required to satisfy more stringent requirements, the requirements specified in 7.1.4.2 or the requirements specified in 7.2.2 of EN 166:2001 shall be met. 4 Testing 4.1 General The testing schedule in Table 3 shall be applied to testing of filters, frames and complete eye-protectors. The sequence of testing 1 to 9 and 13 to 16 may be changed. At least 16 filters or eight complete eye-protectors are required for testing. If testing for several wavelengths (wavelength ranges) or testing conditions according to 4.4 and/or several optional requirements has to be done, more than 16 samples may be necessary.
