This specification covers white or yellow preformed retroreflective pavement marking tapes that are designed to provide a service life of typically 3 to 6 months, on roads with up to 15 000 average daily traffic count (ADT). The tapes are intended for use as longitudinal, transverse, or word/symbol pavement markings that provide delineation day and night. The tapes may be either Type I (removable) or Type II (nonremovable). The marking tape shall be a reflective film coated with a pressure-sensitive adhesive with or without a protective liner. It shall be flexible and shall conform to the the typical road pavement surface. In addition, it shall adhere to asphalt or portland cement concrete roadway surfaces when applied. Also, the marking tape shall be retroreflective, reflecting white or yellow, respectively, and shall be readily visible when viewed with automobile headlights at night and shall have minimum reflective values as specified.

1.1 This specification covers white or yellow preformed retroreflective pavement marking tapes that are designed to provide a service life of typically three to six months, depending on wear and durability factors.

1.2 The tapes are intended for use as longitudinal, transverse, or word/symbol pavement markings that provide delineation day and night. The tapes may be either removable or nonremovable.

1.3 The values stated in inch-pound units are to be regarded as the standard except where noted in the document. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.4 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.
