The scope of this document is to provide an overview of the techniques found in the published literature for rollover testing and rollover crashworthiness evaluation at the vehicle and component levels. It is not a comprehensive literature review, but rather illustrates the techniques that are in use or have been used to evaluate rollover crashworthiness-related issues.

The objective of this document is to enhance the test procedure that is used for ejection mitigation testing per the NHTSA guidelines as mentioned in the FMVSS226 Final Rule document (NHTSA Docket No. NHTSA-2011-0004). The countermeasure for occupant ejection testing is to be tested with an 18kg mass on a guided linear impactor using the featureless headform specifically designed for ejection mitigation testing. SAE does not endorse any particular countermeasure for ejection mitigation testing. However, the document reflects guidelines that should be followed to maintain consistency in the test results. Examples of currently used countermeasures include the Inflatable Curtain airbags and Laminated Glass.

This SAE Recommended Practice establishes a uniform laboratory test method to evaluate the strength characteristics of roof systems. The test procedure is intended to provide reliable and repeatable results and to permit numerical comparisons. A test is conducted in which the vehicle roof system is loaded under controlled laboratory conditions. Structural strength measurements are obtained under load application angles chosen to concentrate forces on the forward portions of the roof panel and roof supporting structure.

Collision tests are conducted on automotive vehicles to obtain information of value in evaluation of structural integrity and in reducing the risk of occupant injuries. The deformation resulting from a moving rigid barrier impact is more severe at a given speed than that produced by using an actual vehicle, but is more readily reproducible than that occurring during vehicle to vehicle impacts. The purpose of this SAE Recommended Practice is to establish sufficient standardization of such moving barriers and moving barrier collision methods so that results of tests conducted at different facilities may be compared.

This SAE Recommended Practice describes the test procedure for conducting a rollover test using a dolly fixture designed to laterally trip a vehicle into a roll. Its purpose is to establish a recommended test procedure which will standardize the procedure between different test facilities. A description of the test procedure, test instrumentation, photographic/video coverage, and the rollover fixture is included.

This SAE Recommended Practice is intended to establish guidelines for conducting passenger car roll-over tests so that data obtained by various test facilities may be more readily compared. A description is provided of the facilities and procedures for a curved rail-ramp technique, which has been found to be successful in producing roll-overs. Techniques and instrumentation for the study and evaluation of vehicle structure effects and occupant movement resulting from roll-overs produced by the curved rail-ramp system are also specified. The curved rail-ramp procedure has been evolved from laboratory and field studies and tests which have sought to establish procedures which would provide realistic simulations of roll-over accidents without collision, and which would be reproducible among laboratories and between different types of passenger cars. The original issue of SAE J857 described ground level and hill roll-over techniques.

Roll-over tests are conducted to evaluate vehicle structure and occupant injury potential. This SAE Recommended Practice is in tended to establish guidelines for conducting passenger car rollover tests for the purpose of standardizing these tests, so that data obtained by various test facilities may be more readily compared. Methods and instrumentation are recommended for the study and evaluation of vehicle structures and occupant movement in simulated roll-over accidents without collision. Procedures and equipment described will be subject to continuing review and will be revised as experience and improvements in the technology warrant.
