ISO 5007:2003根据ISO 10326-1规定了一种实验室方法，用于测量和评估农业轮式拖拉机操作员座椅悬挂的有效性。它还规定了基于试验结果的验收标准，同时定义了与三类农用拖拉机相关的输入光谱等级，这三类拖拉机配有橡胶轮胎、非簧载后轴和无低频驾驶室隔离——最大360kg（1类）、3600kg至6500kg（2类），以及重量超过6500kg（3级）的机器——每种机器定义了一组具有相似振动特性的机器。 该方法测试座椅悬架在降低以1 Hz至20 Hz的频率传递给操作员的垂直全身振动方面的有效性。 它不适用于通过座椅以外的方式到达操作员的振动（例如，操作员在平台上的脚或控制踏板或方向盘上的手感应到的振动）。

ISO 5007:2003 specifies, in accordance with ISO 10326-1, a laboratory method for measuring and evaluating the effectiveness of the suspension of operator seats on agricultural wheeled tractors. It also specifies acceptance criteria based on the test results, while defining the input spectral classes relating to three classes of agricultural tractor with rubber tyres, unsprung rear axles and no low-frequency cab isolation -- those of up to 3 600 kg (class 1), those of from 3 600 kg to 6 500 kg (class 2), and those of over 6 500 kg (class 3) -- each of which defines a group of machines having similar vibration characteristics. The method tests the effectiveness of the seat suspension in reducing the vertical whole-body vibration transmitted to the operator at frequencies of from 1 Hz to 20 Hz. It is not applicable to vibration reaching the operator other than through the seat (e.g. that sensed by the operator's feet on the platform or control pedals or hands on the steering wheel).
