ratio relative to the luminance white level for the same specific viewing direction L(Ɵmonitor/D, ϕ monitor/D) does not exceed 35 per cent of the luminance white level for the monitor standard isotropy range and shall not exceed 50 per cent of the luminance white level for the monitor extended isotropy range.

              For the standard isotropy range:

              ,

              for points i = 1, 2, 3, 4, 5, 6, 7, 8, 9 as defined in Table 1 below.
