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, Comite 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.
