A Tilt Table Procedure for Measuring the Static Rollover Threshold for Heavy Trucks
1998-12-01
HISTORICAL
J2180_199812
The test procedure applies to roll coupled units such as straight trucks, tractor semitrailers, full trailers, B-trains, etc. The test is aimed at evaluating the level of lateral acceleration required to rollover a vehicle or a roll-coupled unit of a vehicle in a steady turning situation. Transient, vibratory, or dynamic rollover situations are not simulated by this test. Furthermore, the accuracy of the test decreases as the tilt angle increases, although this is a small effect at the levels of tilt angle used in testing heavy trucks. The test accuracy is accepted for vehicles that will rollover at lateral acceleration levels below 0.5 g corresponding to a tilt table angle of less than approximately 27 degrees. Even so, the results for heavy trucks with rollover thresholds greater than 0.5 g could be used for comparing their relative static roll stability.

Exterior Sound Level for Heavy Trucks and Buses
2001-04-27
HISTORICAL
J366_200104
This SAE Standard establishes the test procedure, environment, and instrumentation for determining the maximum exterior sound level for highway motor trucks, truck tractors, and buses. The test results obtained by this test procedure give an objective measure of the maximum noise level emitted by vehicles under a prescribed condition. A subjective rating of the annoyance caused by vehicles in use may not be directly related to this type of noise level measurement.

Fifth Wheel Kingpin Performance – Commercial Trailers and Semitrailers
2011-07-13
CURRENT
J133_201107
The purpose of this SAE Recommended Practice is to establish test procedures and minimum performance standards for kingpins and their supporting structure manufactured to SAE specifications. The dimensions shown in SAE J700 will permit the establishment of standard clearances in the installed condition which, in turn, will permit fifth wheel manufacturers to design their products to establish interchangeability with any kingpin made and installed to the SAE specification.
