This Recommended Practice covers service performance tests, test methods, and requirements applicable to sealed beam headlamp units covered by SAE J579 and J571. It is intended to supplement the dimensional requirements and engineering design test procedures and requirements, and is the means for service evaluation of sealed beam headlamp units.
These criteria apply to pneumatic-tired prime movers such as those used to pull scrapers, water wagons, bottom dump wagons, side dump wagons, rear dump wagons, and towed fifth wheel attachments. (See SAE J869, J728, and J734 for description and nomenclature.) Because, this recommended practice presents both procedure and criteria that are intended for consideration as worldwide standards for ROPS, the following points are explicitly stated to aid in understanding its underlying principles, intention, and application.
The static laboratory test will test the adequacy of the ROPS used to protect the operator during the following vehicle operation: Vehicle operating over hard clay where roll-over would be limited to a roll angle of 360 deg or less and speed would be limited to 10 mph or less.
The static laboratory test will test the adequacy of the structures used to protect the operator during the following vehicle operation: Vehicle operating 0-10 mph over hard clay where roll-over would be limited to a maximum roll angle of 360 deg down a slope of 30 deg maximum.
These criteria apply to pneumatic-tired self-propelled motor graders. (See SAE J870 for description and nomenclature.) Because this recommended practice presents both procedure and criteria that are intended for consideration as worldwide standards for ROPS, the following points are explicitly stated to aid in understanding its underlying principles, intention, and application.
The static laboratory test will test the adequacy of the structures used to protect the operator during the following vehicle operation: Vehicle operating at 0-10 mph over hard clay where rollover would be limited to a maximum roll angle of 360 deg down a slope of 30 deg maximum. This criteria applies to loaders classified as construction equipment.
These criteria apply to wheeled front-end loaders and wheeled dozers. Because this recommended practice presents both procedure and criteria that are intended for consideration as worldwide standards for ROPS, the following points are explicitly stated to aid in understanding its underlying principles, intention, and application.
This SAE Recommended Practice provides tire dimensions and uniform laboratory test procedures for evaluating certain essential characteristics of new pneumatic tires intended primarily for highway use on trucks, buses, trailers, and multipurpose passenger vehicles. (The requirements and test procedures published in this SAE recommended practice pertain to tire sizes currently used in the United states on trucks, buses, trailers, and multipurpose passenger vehicles. For related information on tire sizes not listed, contact Society of automotive Engineers, Inc., Detroit Branch Office, 18121 East eight Mile road, East Detroit, Michigan 48021.)
The static laboratory test will test the adequacy of the structures used to protect the operator during the following operation: Vehicle operating 0-10 mph over hard clay where roll-over would be limited to 360 deg down a slope of 30 deg maximum. This criteria applies to graders classified as construction equipment.
