New Specification for Standard Specification for Photoluminescent (Phosphorescent) Safety Markings
1. Scope
1.1 This specification covers minimum performance 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 E2073 and Guide
E2030).
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 inch-pound units are to be regarded
as standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only
and are not considered standard.
E12.13 subcommittee has had Standard E2072 for many years. Standard Specification E2072-14 recently expired since E12.13 did not have a successful ballot action in time for renewal. ASTM Regulations required automatic withdrawal of this standard due to old age (year 2014 edition). Following the June 2023 subcommittee meeting, members were invited to join a task group to work on improving E2072-14. The task group participants were Charles Barlow, Marina Batzke and Mark Watson. The task group feedback was incorporated into a suggested draft of E2072 that shall go for ballot. At the Jan. 2024 virtual meeting, it was decided to go into concurrent Sub- and Main Committee ballot with this improved E2072 standard.
