CONTAINED IN VOL. 04.03, 2015 Defines determination of an average stopping distance number (SDN) under the conditions that this method was executed.

1.1This test method covers determination of an average stopping distance number (SDN) under the conditions that this method was executed. The experimental conditions are generally intended to be similar to those of a specified traffic incident. The data from this method is not comparable to measured distances of a specified traffic incident vehicle that cannot be shown to have continuous, full application of its braking system.

1.2This test method determines the SDN from the measured stopping distance and initial speed when the wheels on specified axles are braked in the same manner as the specified traffic incident vehicle. The evaluation vehicle’s braking system is required to duplicate the specified incident vehicle for both type (conventional, partial ABS, or full ABS) and functionality (all brakes functional or not).

1.3The method documents the test conditions as a basis for evaluating their similarity to conditions of a specified traffic incident.

1.4The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the test, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.

1.5This standard may involve hazardous materials, operations, and equipment. 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.
