For all formats of safety signs, the maximum viewing distances and luminance conditions are given in EN 1838: 2013. Signs can be either internally illuminated, such as exit boxes or edge lit luminaires with a screened sign that have a controlled illuminance or painted signs. These include photoluminescent signs, but to be acceptable they must have an external lighting illuminating them in normal condition to OX[ DQG OX[ RQ DQ\ SDUW RI WKH IDFH XQGHU PDLQV IDLOXUH FRQGLWLRQ 0D[LPXP YLHZLQJ GLVWDQFHV DUH
