A Tilt Table Procedure for Measuring the Static Rollover Threshold for Heavy Trucks

2011-05-17
CURRENT
J2180_201105
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.

Thermal Containment Efficiency of Sleeve Materials

2008-09-04
HISTORICAL
J2495_200809
This SAE Standard measures the percent thermal efficiency of materials in sleeve form used to contain heat or insulate around a hot component. The percent thermal efficiency (%TE) is determined by measuring the power difference expended by the heat source (cartridge heater) with and without the test sleeve at the specified temperature. See SAE J2302 to measure radiant heat flow of sleeves.

The flanges covered by this document are designated type A and type S. The type A flanges are equivalent to type A ISO 7646. The type S flanges are equivalent to the type S ISO 7647. Type A is an external (male) pilot construction and type S is an internal (female) pilot construction. These flanges are not interchangeable. Dimensions not specified are left to the discretion of the component manufacturer.

Life Cycle Testing of Electric Vehicle Battery Modules

1997-01-01
HISTORICAL
J2288_199701
This SAE Recommended Practice defines a standardized test method to determine the expected service life, in cycles, of electric vehicle battery modules. It is based on a set of nominal or baseline operating conditions in order to characterize the expected degradation in electrical performance as a function of life and to identify relevant failure mechanisms where possible. Accelerated aging is not included in the scope of this procedure, although the time compression resulting from continuous testing may unintentionally accelerate battery degradation unless test conditions are carefully controlled. The process used to define a test matrix of accelerated aging conditions based on failure mechanisms, and to establish statistical confidence levels for the results, is considered beyond the scope of this document. Because the intent is to use standard testing conditions whenever possible, results from the evaluation of different technologies should be comparable.
