5.1 It is important to obtain a truly representative sample of the thermoplastic pavement marking material prior to performing any tests. This can be difficult due to the wide ranges of sizes, shapes, and densities of the individual components that are used in the manufacture of these types of materials. The sample that is obtained using this guide should be representative of the manufactured lot from which it was obtained and can be used for the testing of the chemical and physical properties of the material as required by the governing specification.1.1 This practice covers the proper field sampling of thermoplastic pavement marking materials to ensure test results are representative of the material being tested.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.3 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.1.4 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.

5.1 This practice provides a standard procedure for the preparation of thermoplastic pavement marking material test specimens prior to testing for various properties as called for in the governing specification. Specimens that are prepared using this standard methodology yield test results that are consistent with the material from which it was sampled. Test results from specimens can be used to determine compliance of the thermoplastic pavement marking material to the specification. This practice can also be used by manufacturers of these materials to prepare specimens for testing to determine the uniformity of thermoplastic pavement marking materials from batch to batch.5.2 This practice does not address any issues related to specific testing of the thermoplastic pavement marking materials for any physical or chemical property.1.1 This practice covers the proper preparation of test specimens of thermoplastic pavement marking materials obtained to ensure test results are representative of the material being tested.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.3 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.1.4 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.

4.1 This practice establishes the criteria to treat, or mark, or both WPM with permanent identification for the phytosanitary treatment, or intended service cycle, or both, repair, specification used, and other designated characteristics.4.2 The marking of the WPM shall be performed after ensuring the material complies with the applicable specification.1.1 This practice covers the development of recommended treatment, or marking practices, or both, for wood packaging materials (WPM) and aids in identifying WPM as to phytosanitary treatment, intended service cycles, repair, the specific specification used to manufacture or recycle, and other user designated characteristics.1.2 This practice identifies WPM treated, or marked, or both in accordance with industry, government, or international recognized standards.1.3 The values stated in inch-pound units are to be regarded as standard. 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 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 and health practices and determine the applicability of regulatory limitations prior to 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.

1.1 This practice covers the selection and use of a portable retroreflectometers for the measurement at a prescribed geometry of the retroreflective properties of horizontal pavement marking materials containing glass spheres, such as traffic stripes and surface symbols. 1.2 The entrance and observation angles provided in the retroreflectometer greatly affect the test results and must be a major consideration in the selection of the instrument. Information on the relationship between instrument geometry and viewing geometry is provided in Section 5. Information on viewing geometry is provided in Table 1. Information on the relationship between viewing geometry and coefficient of retroreflected luminance, RL is given in fig. 1. 1.3 This practice is intended to be used for selection of portable retroreflectrometers for field measurement of pavement markings but may also be used to select portable retroreflectometers 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. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
