Причина отмены

This test method describes the instrumental measurement of the colorimetric properties (CIE tristimulus values, luminance factors, and chromaticity coordinates) of fluorescent-retroreflective sheeting and marking materials when illuminated by daylight.

Formerly under the jurisdiction of Committee E12 on Color and Appearance, this test method was withdrawn in April 2012 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the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.

Значение и использование

This test method provides procedures for obtaining tristimulus values, luminance factors and chromaticity coordinates of fluorescent-retroreflective materials by bispectral colorimetry using a 45:0 or 0:45 optical measuring system.

The CIE 1931 (2°) standard observer is used to calculate the colorimetric properties of fluorescent-retroreflective sheeting and markings used in daytime high visibility traffic control and personal safety applications because in practice these materials are primarily viewed from a distance where they subtend less than 4° of the visual field.

This test method is applicable to object-color specimens of any gloss level.

Due to the retroreflective properties of these materials the colorimetric data may not be suitable for use in computer colorant formulation.

This test method is suitable for quality control testing of fluorescent-retroreflective sheeting and marking materials.

Note 1—Separation of the fluorescence and reflectance components from the total colorimetric properties provides useful and meaningful information to evaluate independently the luminescent and diffuse reflective efficiency and consistency of these materials.

This test method is the referee method for determining the conformance of fluorescent-retroreflective sheeting and marking materials to standard daytime colorimetric specifications.

Область применения

1.1 This test method describes the instrumental measurement of the colorimetric properties (CIE tristimulus values, luminance factors, and chromaticity coordinates) of fluorescent-retroreflective sheeting and marking materials when illuminated by daylight.

1.2 This test method is generally applicable to any sheeting or marking material having combined fluorescent and retroreflective properties used for daytime high visibility traffic control and personal safety applications.

1.3 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.
