Installation Site5.1 On-

10、Site LuminanceThe photopic luminance of on-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 le

19、ONSX2.1 In 5.1, On-Site Luminance, Specification E2072 re-quires luminance values at 10 and 60 min. after on-siteactivation has ceased. These values are to be measured at theinstallation site, following Test Method E2073.X2.2 Accomplishing the required luminance values dependson a variety of factors

20、, including but not limited to, the type ofactivating light source, the intensity of illumination (lx/fc) onthe marking surface, the color temperature of illumination (K,Kelvin), the length of illumination and the ambienttemperature, to mention a few factors.X2.3 How different the luminance results

21、may be, depend-ing on changing illumination conditions, is shown in TableX2.1. The luminance values in the table are averages forrandomly selected products. Results will vary for othersamples and other activation conditions.E2072 142X3. SUMMARY OF CHANGESX3.1 This specification was originally publis

These values stayed through the 2010 edition andwere updated to harmonize with U. S. Code requirements in the2014 edition.ASTM International takes no position respe
