The on-site lighting shall be used as activation. Markings must be a minimum of 1-in.(25.4-mm) width. For markings of width The

15、 W, the required photopic luminance shall, at all times, be not less than:1500/Wmcd/m2 at 10 min after activation has ceased30 mcd/m2 at 10 min after activation has ceased;and 5 mcd/m2 at 90 min after activation has ceased.220/W mcd/m2 at 60 min after activation has ceasedFor this calculation, the w

LUMINANCE COMPARISON FOLLOWING DIFFERENT ILLUMINATION CONDITIONSX2.1 In 5.1, On-Site Luminance, Specification E2072 requires luminance values at 10 and 60 min. after on-site activation hasceased. These values are to be measured at the installation site, following

23、Test Method E2073.X2.2 Accomplishing the required luminance values depends on a variety of factors, including but not limited to, the type ofactivating light source, the intensity of illumination (lx/fc) on the marking surface, the color temperature of illumination (K,Kelvin), the length of illumina

24、tion and the ambient temperature, to mention a few factors.X2.3 How different the luminance results may be, depending on changing illumination conditions, is shown in Table X2.1. Theluminance values in the table are averages for randomly selected products. Results will vary for other samples and oth

SUMMARY OF CHANGESX3.1 This specification was originally published in 2000 with luminance values of 20.0 mcd/m2 at 10 min after activation hasceased and 2.8 mcd/m2 at 60 min after activation has ceased. These values stayed through the 2010 edition and were update
