| Published By | Publication Date | Number of Pages |
| ASTM | 2009 | 3 |
1.1 This specification covers minimum photometric requirements for newly applied photoluminescent (phosphorescent) safety materials used to provide supplemental markings of escape routes, emergency equipment, and obstructions along the escape route. (see also Test Method E 2073 and Guide E 2030 ).
1.2 This specification establishes minimum luminance values for photoluminescent (phosphorescent) markings.
1.3 This specification applies to all types of photoluminescent (phosphorescent) markings, including but not limited to plastics, coatings, ceramics, films, etc.
1.4 This specification does not cover potentially diminished performance due to wear and tear and aging.
1.5 This specification applies only to photoluminescent (phosphorescent) markings emitting the majority of spectral energy within the 515 to 535 nanometer range.
1.6 When reference is made regarding photoluminescence in the text of this standard, it implies phosphorescence.
1.7 The values stated in SI units are the standard. The values given in parentheses are provided for information purposes only.
