Standard Test Method for Nighttime Retroreflected Chromaticity of Retroreflective Sheeting

Importancia y uso:

5.1 The results of this test method are used to assess conformance of retroreflective sheeting to the nighttime color requirements of industry standards and government regulations, such as Specification D4956 and U.S. Code of Federal Regulations Title 23 Part 655 Subpart F.

5.2 Requirements in specifications referring to this test method are for the chromaticity of the material as viewed at night. These requirements are generally stated using four or five corner points that form a box that limits the range of acceptable chromaticity. Most of these specifications are categorical in nature; they describe a small range of colors that are recognizable from a color naming or coding purpose

5.3 The method for compliance with the specification is to plot the measured (x, y) values and determine if the measured point falls within the specification box for the color of interest.
