5.1 The quality of the stripe is determined by the coefficient of retroreflected luminance, RL, and depends on the materials used, age, and wear pattern. These conditions shall be observed and noted by the user.5.2 Under the same conditions of illumination and viewing, larger values of RL correspond to higher levels of visual performance.5.3 Retroreflectivity of pavement (road) markings degrade with traffic wear and require periodic measurement to ensure that sufficient line visibility is provided to drivers.5.4 For a given viewing distance, measurements of RL made with a retroreflectometer having a geometry corresponding to that viewing distance are a good indicator of the visual ranking of material measured.5.5 As specified by CEN, the measurement geometry of the instrument is based on a viewing distance of 30 m, a headlight mounting height of 0.65 m directly over the stripe, and an eye height of 1.2 m directly over the stripe.5.6 It shall be the responsibility of the user to employ an instrument having the specified observation and entrance angles.1.1 This test method covers measurement of the retroreflective properties of horizontal pavement marking materials containing retroreflecting beads, such as traffic stripes and surface symbols, using a portable retroreflectometer that can be placed on the road delineation to measure the retroreflection at a prescribed geometry.NOTE 1: The restriction to bead based materials is for the purpose of ensuring a sufficiently gradual optical response function (from points of the source aperture to points of the receiver aperture) to allow generous sized instrument source and receiver apertures.1.2 The entrance and observation angles of the retroreflectometer affect the readings. As specified by the European Committee for Standardization (CEN), the entrance and observation angles shall be 88.76° and 1.05°, respectively.1.3 This test method is intended to be used for field measurement of pavement markings but may be used to measure the performance of materials on sample panels before placing the marking material in the field.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

4.1 Aircraft flying in national airspace are required by the ICAO Chicago Convention and national regulatory rules to have visible markings to determine nationality and registration. UAS shall comply with these rules, although small UAS will have unique rules or exemptions from existing rules due to their small size. This standard is designed to allow UAS to comply with these marking requirements in Annex 7 to the Convention on International Civil Aviation as amended by state regulatory rules.4.2 Many ICAO states are assigning UAS to different classes and categories to define the rules UAS must operate under. The ICAO Annex 7 Standards and Recommended Practices (SARPS) apply to UAS Aircraft with the exception of small UAS. The classification of what constitutes a small UAS (sUAS) has been left to ICAO states and the rules under which sUAS operate are dictated by each state.4.3 This practice follows ICAO Annex 7 SARPS except in areas where the unique aspects of UAS may not allow compliance. In these cases, this document will address the issue and recommend the need for an alternate compliance method.1.1 This practice prescribes guidelines for the display of marks to indicate appropriate UAS registration and ownership for all Unmanned Aircraft Systems (UAS) except those categorized as small UAS (sUAS) by regulatory authorities. The FAA is developing a Special Federal Aviation Regulation (SFAR) to define the term small UAS and provide regulations for these aircraft.1.2 This practice will allow determination of nationality in cases where UAS may cross international boundaries.1.3 This practice does not apply to sUAS. The International Civil Aviation Organization (ICAO) has left the designation of sUAS to each state and the states will develop rules and regulations for sUAS.1.4 This practice does not apply to model aircraft.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.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.
