SAE J1194, Rollover Protective Structures (ROPS) for Wheeled Agricultural Tractors
Published by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.orgASAE J1194 November 2016
Although SAE J1194, Rollover Protective Structures (ROPS) for Wheeled Agricultural Tractors, is stabilized, ASABE technical committee MS 23/2/2, Ag Tractors ROPS, recommends the use of the state-of-the-art ROPS standards, which are available through the ASABE Technical Library and are as follows:
1) ASABE/ISO 5700:2013, Tractors for agriculture and forestry — Roll-over protective structures — Static test method and acceptance conditions; and
2) ASABE/ISO 3463:2006, Tractors for agriculture and forestry — Roll-over protective structures (ROPS) — Dynamic test method.
3) ASABE/ISO 12003-2:2008 ROPS for narrow tractors - Part 2: Rear-mounted ROPS
Access to the cited SAE standards are also available through ASABE.
Approved by ASABE Committee MS-23/2/2 January 30, 2020.

1.1 Fulfillment of the intended purpose requires testing as follows:
1.1.1 A laboratory test, under repeatable and controlled loading, to permit analysis of the ROPS for compliance with the performance requirements of this SAE Standard. Either the static test (6.1) or the dynamic test (6.2) shall be conducted.
1.1.2 A crush test to verify the effectiveness of the deformed ROPS in supporting the tractor in an upset attitude.
1.1.3 A field upset test under reasonably controlled conditions, both to the rear and side, to verify the effectiveness of the protective system under actual dynamic conditions. (See 188.8.131.52 for requirements for the omission of this test.)
1.1.4 In addition to the laboratory and field loading requirements, there is a temperature-material requirement (see 7.1.2).
1.2 The test procedures and performance requirements outlined in this document are based on currently available engineering data.
1.3 Purpose―The purpose of this document is to establish the test and performance requirements of a rollover protective structure (ROPS) designed for wheel-type agricultural tractors to minimize the frequency and severity of operator injury resulting from accidental upsets. All self-propelled implements are excluded.(Download PDF) (Export to EndNotes)
