(Test Method)Standard Test Method for Photopic Luminance of Photoluminescent (Phosphorescent) Markings (Withdrawn 2019)
Standard Test Method for Photopic Luminance of Photoluminescent (Phosphorescent) Markings (Withdrawn 2019)
SIGNIFICANCE AND USE
To assess how photoluminescent markings perform under identical test conditions, the luminance shall be measured in accordance with this test method (see Specification E 2072).
SCOPE
1.1 This test method covers a procedure for determining the photopic luminance of photoluminescent (phosphorescent) markings. It does not cover scotopic or mesopic measurements.
1.2 When reference is made regarding photoluminescence in the text of this test method, it implies phosphorescence.
1.3 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.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
WITHDRAWN RATIONALE
This test method covers a procedure for determining the photopic luminance of photoluminescent (phosphorescent) markings. It does not cover scotopic or mesopic measurements.
Formerly under the jurisdiction of Committee E12 on Color and Appearance, this test method was withdrawn in January 2019 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
