significance And Use:

scope:

1.1 This test method measures an automatic/automated/autonomous-unmanned ground vehicle (A-UGV) kinetic energy reduction when objects appear in the A-UGV path and within the stop-detect range of the vehicle safety sensors in situations in which the desired reaction is for the vehicle to stop as opposed to avoiding the obstacle by traveling on an alternative path. The test method measures the performance of the A-UGV only and does not measure the effect on the stability of loads. This test method describes the use of one test piece as described in ANSI/ITSDF B56.5. Other test pieces from ANSI/ITSDF B56.5 could be used. This test method is intended for use by A-UGV manufacturers, installers, and users. This test method does not substitute for required safety testing under ANSI/ITSDF B56.5 or other normative standards.

1.2 Performing Location-This test method shall be performed in a testing laboratory or the location where the apparatus and environmental test conditions are implemented. Environmental conditions are recorded as specified in Practice F3218.

1.3 Units-The values stated in SI units are to be regarded as the standard. The values given in parentheses are not precise mathematical conversion to inch-pound units. They are close approximate equivalents for the purpose of specifying material dimensions or quantities that are readily available to avoid excessive fabrication costs of test apparatuses while maintaining repeatability and reproducibility of the test method results. These values given in parentheses 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, health and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 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.
