ASTM WK35613

    New Practice for Standard Practice for Measuring Retroreflective Signs Using Mobile Equipment

    (What is a Work Item?)

    Developed by Subcommittee: E12.10 | Committee E12 | Contact Staff Manager


    1. Scope

    This practice covers the use of mobile equipment to measure the retroreflective properties of sign materials such as traffic signs and symbols (vertical surfaces). The mobile retroreflectometer is a vehicle-mounted system that can be used at highway speeds to measure retroreflective properties of traffic signs.

    The need is based on the new US regulations to maintain traffic sign retroreflectivity at specified levels.


    sign retroreflectivity; retroreflected luminance; retroreflectance

    The title and scope are in draft form and are under development within this ASTM Committee.
