1.1 本规范涵盖了用于道路表面交通控制车道标线和符号的反光路面标线材料的日间和夜间颜色。 1.2 本规范适用于所有反光路面标记（包括位于表面的反光光学器件的标记） 3.2.5 。 1.3 本规范不适用于表面不包括反光光学器件的路面标线。 1.4 本规范不涉及除反光路面标线颜色以外的任何要求。 1.5 以国际单位制表示的数值应视为标准。本标准中不包括其他计量单位。 1.5.1 例外-- 本规范是一份国际单位制文件，其中角度通常以弧度表示。 然而，由于回射中使用的角度历来以度为单位，国际度量衡委员会（CIPM，国际计量委员会）接受使用国际单位制的度，而欧洲规范和国际照明委员会（CIE）的文件则将度用于回射几何。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

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. 1.2 This specification applies to all retroreflective pavement markings (markings that include retroreflective optics residing on the surface) except structured pavement markings as defined in 3.2.5 . 1.3 This specification is not applicable to pavement markings that do not include retroreflective optics on the surface. 1.4 This specification does not address any requirements other than the color of retroreflective pavement markings. 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 an 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. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
