规定了用于评估安装在后轮距通常大于1150 mm的拖拉机上的防滚翻保护结构的试验程序和最低性能标准。它适用于驾驶员控制的拖拉机，但不包括土方设备。它包括静态和动态测试的测试程序。包括翻滚保护结构的理论分析，该结构将提供与物理测试同等的性能。

Specifies the test procedures and minimum performance criteria for evaluating roll-over protective structures fitted to tractors having a rear track width generally greater than 1150 mm. It applies to driver-controlled tractors, but does not cover earth-moving equipment. It includes test procedures for both static and dynamic testing. A theoretical analysis of roll-over protective structures, which would provide equivalent performance to physical testing, is included.
