Luminance measurements of C0 values shall be made within 5° from the normal to the face
of the exit sign,using a meter with a circular measurement field of diameter not less than
75% and not more than 85% of the arm width as specified in Figure 3.4.Luminance
measurements of C60 (horizontal) values shall be made at an angle between 55° and 75° in
the horizontal plane to the normal to the face of the sign.
