(Specification)Standard Specification for Color of Pavement Marking Materials
Standard Specification for Color of Pavement Marking Materials
ABSTRACT
This specification covers the daytime and nighttime color of retroreflective pavement marking materials, both painted and tape lines, including thermoplastic, epoxy and other types, used for traffic control lane markings and symbols on road surfaces. This specification is not applicable to the testing, for quality control purposes, of marking material without added drop-on beads. The performance requirements for which the marking materials shall be tested on and conform accordingly to are the daytime and nighttime chromaticity limits, retroreflectance, and daytime lightness limits (Y tristimulus coordinate).
SCOPE
1.1 This specification covers the daytime and nighttime color of retroreflective pavement marking materials used for traffic control lane markings and symbols on road surfaces. It is intended to apply throughout the service life of the material.
1.2 This specification applies to both painted and tape lines, including thermoplastic, epoxy and other types.
1.3 This specification is not applicable to the testing, for quality control purposes, of marking material without added drop-on beads.
1.4 In addition, it does not describe requirements other than color such as retroreflectance.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5.1 Exception—This specification is noted to be a SI document, where angles are generally expressed in radians. However, as angles used in retroreflection have historically been identified in degrees, the International Committee for Weights and Measures (CIPM, Comité International des Poids et Mesures) accepts the use of degrees with SI units, and European Normatives and documents from the International Commission on Illumination (CIE) use degrees for retroreflection geometry.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
