SAE J2664_201710建立了一个一致的程序，用于测量和分析特定挂车在特定载荷和操作条件下连接到特定车辆时的自然摇摆响应。本试验程序适用于但不限于乘用车、厢式货车、作为牵引车的轻型/中型卡车，以及额定车辆总重（GVWR）为11794 kg（26000 lb）或以下的半挂车。其他应用包括全拖车、拖车、拖车杆等。其他铰接式车辆可以使用该测试程序，只要测试不超过系统的线性行为。本试验程序不适用于牵引挂车的摩托车。

SAE J2664_201710 establishes a consistent procedure for measuring and analyzing the natural sway response of a particular trailer when attached to a particular vehicle under specific loading and operating conditions. This test procedure applies, but is not limited to, passenger cars, vans, light/medium-duty trucks as tow vehicles, and semitrailers with a Gross Vehicle Weight Rating (GVWR) of 11794 kg (26000 pounds) or less. Other applications include full trailers, tow dollies, tow bars, and the like. Other articulated vehicles can utilize this test procedure as long as the test does not exceed the linear behavior of the system. This test procedure does not apply to motorcycles towing trailers.
