The scope of this document is limited specifically to the following types of passenger vehicles: automobiles, light trucks, and sport/utility vehicles. This document addresses modifications as they apply to legal use of the vehicle, and examines suspension modification as it applies to stock (as manufactured) ride height, and changed (raised or lowered) ride height. Note that modifications of ride height are considered, exclusive of wheel and/or tire modifications, which can also have potentially serious side effects, and are outside the scope of this document.

This SAE Recommended Practice describes a laboratory test procedure for evaluating the loss of thickness and the amount of structural breakdown of slab polyurethane foam seating materials. A test specimen is measured for thickness under a specified load and subsequently subjected simultaneously to compressive and shear deformation in a controlled atmosphere. This is accomplished by subjecting the foam to a rolling shearing action under a constant load for a specified number of cycles. Specimen thickness under a constant load is obtained after a 1hr recovery period following dynamic fatigue to determine loss in foam thickness.

This SAE Recommended Practice specifies design recommendations for the location of seat belt assembly anchorages which will promote proper transfer of occupant restraint forces on the strongest parts of the human anatomy to the vehicle or seat structure. Test procedures are specified in SAE J384.

This SAE Recommended Practice defines the information required to repair the various types of plastics found on modern light-duty highway vehicles. Information is included for the repair and refinishing of most plastic body parts, both interior and exterior. Repair information is described for all commonly used plastics including, but not limited to, polyurethanes, polycarbonate blends, modified polypropylenes, polyethylenes and nylons. Repairs can be made to these types of plastics using two-part (2K) repair adhesives, plastic welding, and other materials available from body shop suppliers. When a new type of plastic is being introduced to the market through a new vehicle program, specific repair and refinishing procedures should be provided, following the format in this document. Sheet-molded compounds (SMC), fiber-reinforced plastics (FRP) and carbon fiber reinforced plastics can also be repaired using slightly different procedures and repair materials.

This SAE Recommended Practice is designed to provide readily accessible paint and trim code information on all passenger vehicles, lightweight trucks, and vans in a way that minimizes the time and effort required to locate and effectively use that information for body repair, parts ordering, vehicle maintenance, and information systems.

This SAE Recommended Practice describes performance requirements for hardware used in motor vehicle seat belt assemblies when tested in accordance with the test procedures specified in SAE J140. Test procedures and performance requirements for retractors will be covered in separate SAE Recommended Practices to be issued later.

Almost all light trucks now are being manufactured with at least a driver side air bag and all will have dual air bags by 1998. The driving forces behind this feature are occupant safety, federal regulations, and competition in the industry. Along with the booming popularity of pickups and SUVs, they are commonly accessorized with a wide variety of products. Many accessories for four-wheel drives in particular are mounted on the front of the vehicle. These products include grille/brush guards, winches, snow plows, replacement bumpers, bicycle carriers, etc. Concerns have arisen over the compatibility of these accessories with the vehicle’s air bag system. The vehicle manufacturers are concerned because of their huge investment in design and crash test verification of the complete vehicle system and keen awareness of the federal regulations. The crushability of the front bumper and supporting structure are key elements in the system, so alterations to that area become logical concerns.
