Standard Test Method for Measuring Gradation of Glass Spheres Using a Flowing Stream Digital Image Analyzer

Importancia y uso:

5.1 The gradation (size distribution) of glass beads has a significant influence on the retroreflective efficiency of a pavement marking system.

5.2 This test method is for the characterization of the gradation (size distribution) of glass beads for the purpose of compliance testing against standard specification for glass beads in pavement marking applications.

5.3 While there are potential industrial applications for this test method beyond the measurement of gradation (size distribution) of glass beads for pavement markings, those are beyond the scope of this standard.
