devices of Class IV A the CIL values must be at least equal to those in the table below, expressed in millicandelas per lux, for the angles of divergence and illumination shown.

       4. When the CIL of a retro-reflecting device is measured for an angle beta of V = H = 0 degrees, it shall be ascertained whether any mirror effect is produced by slightly turning the device.  If there is any such effect, a reading shall be taken with an angle beta of

       V = +/- 5 degrees, H = 0 degrees. The position adopted shall be that corresponding to the minimum CIL for one these positions.

       4.1. With and illumination angle beta of V = H = 0 degrees, or the angle specified in paragraph 4 above, and an angle of divergence of 20', retro-reflecting devices which are not marked "TOP" shall be rotated about their axes of reference to the position of minimum CIL, which must conform to the value specified in paragraph 3 above. When the CIL is measured for the other angles of illumination and divergence, the retro- reflecting device shall be placed in the position corresponding to this value of e. If the specified values are not attained, the device may be rotated about its axis of reference ? 5 degrees from that position.

       4.2. With an illumination angle beta of V = H = 0 degrees, or the angle specified in paragraph 4 above, and an angle of divergence of 20', retro-reflecting devices marked "TOP" shall be rotated about their axes +/- 5 degrees. The CIL must not fall below the prescribed value in any position assumed by the device during this rotation.

       4.3. If for the direction V = H = 0 degrees, and for e = 0 degrees the CIL exceeds the specified value by 50% or more, all measurements for all angles of illumination and divergence shall be made for e = 0 degrees.
