12.1.2.3-1 Illumination Levels

The illumination levels should be consistent with those listed in Table 12.1.

Additional Information:
The values in the table are preferred levels based on conservative assumptions about the reflectance of the task background, the age of the operator, and the criticality of the task being performed. Lower illuminances may be justified for more favorable visual conditions or where the need to perform critical tasks can be ruled out.
