9、 90 min after activation has ceased.4.2 Walking Surfaces Materials:4.2.1 Photoluminescent safety markings intended to beinstalled on walking surfaces of the means of egress shall havea slip-resistant surface and be securely attached.5.Installation Site5.1 On-Site LuminanceThe photopic luminance of o
10、n-siteinstalled photoluminescent markings shall be measured incompliance with Test Method E2073.The on-site lighting shallbe used as activation.Markings must be a minimum of 1-in.(25.4-mm)width.The required photopic luminance shall,at alltimes,be not less than:30 mcd/m2at 10 min after activation has
11、 ceased;and 5 mcd/m2at 90 min after activation has ceased.5.2 ActivationThe required recharging activation level forphotoluminescent safety markings depends on the ambientluminance level,the type of light source utilized,and theduration of exposure to the activating light source.Consultmanufacturers
