ASTM E 2521:2024

1.1 This terminology identifies and precisely defines terms as used in the standard test methods, practices, and guides for evaluating response robots intended for hazardous environments. Further discussions of the terms can be found within the standards in which the terms appear. 1.2 The term definitions address response robots, including ground, aquatic, and aerial systems. Some key features of such systems are remotely operated from safe standoff distances, deployable at operational tempos, capable of operating in complex environments, sufficiently hardened against harsh environments, reliable and field serviceable, durable or cost effectively disposable, and equipped with operational safeguards. 1.3 Units- Values stated in either the International System of Units (metric) or U.S. Customary units (inch-pound) are to be regarded separately as standard. The values stated in each system may not be exact equivalents. Both units are referenced to facilitate acquisition of materials internationally and minimize fabrication costs. Tests conducted using either system maintain repeatability and reproducibility of the test method and results are comparable. 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.
