Standard Guide for Measuring Roundness of Glass Spheres Using a Flowing Stream Digital Image Analyzer

Importancia y uso:

4.1 The roundness of glass beads has a significant influence on the retroreflective efficiency of a pavement marking system.

4.2 The guide is for the characterization of the roundness of glass beads for the purpose of compliance testing against standard specification for glass beads in pavement marking applications.

4.3 While there are potential industrial applications for this guide beyond the measurement of roundness of glass beads for pavement markings, those are beyond the scope of this standard.
