根据ISO 10326-1，本国际标准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装置——最大360kg（1类）、最大3600kg至6500kg（2类），以及重量超过6500kg（3级）的机器，每个机器定义了一组具有相似振动特性的机器。

This International Standard 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.
