Standard Specification for Photoluminescent (Phosphorescent) Safety Markings

SCOPE
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 other potentially dangerous objects. (see also Test Method E 2073, Test Method for Photopic Luminance of Photoluminescent (Phosphorescent) Markings, and Guide E 2030, Guide for Recommended Uses of Photoluminescent Safety Markings).
1.2 This specification establishes minimum luminance values for photoluminescent (phosphorescent) markings for detection in clear air under blackout conditions.
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.

Standard Specification for
Photoluminescent (Phosphorescent) Safety Markings
This standard is issued under the fixed designation E 2072; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
e NOTE—Editorial changes were made throughout in June 2002.
