SINCAP MDB - 51<br />

C. The centerline of the MDB shall be perpendicular 90° ± 1.5° to the centerline of the test<br />

vehicle at the time of impact.<br />

D. The MDB shall be crabbed at an angle of 27° ± 1° to the line of forward motion. This<br />

crabbed impactor position simulates a moving vehicle-to-vehicle collision.<br />

E. The MDB’s impact speed shall be 61.90 ± 0.80 km/h.<br />

F. The longitudinal impact tolerance is ± 51 mm (between MDB and test vehicle).<br />

G. The vertical impact tolerance is ± 20 mm.<br />

H. The MDB brakes shall be applied 1,000 to 1,500 milliseconds (1- 1.5 seconds) after the<br />

side impact (duration of MDB/vehicle contact is approximately 150 milliseconds).<br />

12. POST-TEST MEASUREMENTS AND OBSERVATIONS<br />

After the test, the information specified in the following sections shall be recorded on the<br />

applicable Data Sheets (see APPENDIX E).<br />

Record the following information post-test on the applicable Data Sheets in APPENDIX E.<br />

12.1 TEST SPEED AND RELEVANT ANGLES<br />

Record the test speed (km/h) recorded by the primary and redundant speed traps. Also record<br />

the angles between the following:
