1.1This 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.
1.2This specification applies to both painted and tape lines, including thermoplastic, epoxy and other types.
1.3This specification is not applicable to the testing, for quality control purposes, of marking material without added drop-on beads.
1.4In addition, it does not describe requirements other than color such as retroreflectance.
1.5The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5.1Exception—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.
