ISO 5131:2015规定了用于农业和林业的拖拉机操作员位置处噪声的测量和报告方法。测得的噪声仅与基本机器有关，适用于配有机器操作员的拖拉机。这些结果为操作员提供了信息，以避免暴露在可能危及听力的噪音水平下。 测量期间机器运行的规定条件旨在为操作员操作机器时应承受的最大噪音提供真实且可重复的评估。 本国际标准中规定的试验程序是ISO 12001中定义的调查方法。

ISO 5131:2015 specifies a method for the measuring and reporting of the noise at the operator(s) position of a tractor used in agriculture and forestry. The measured noise relates only to the basic machine and applies to tractors with machine-carried operators. The results provide information to the operator(s) in order to avoid exposing themselves to noise levels that could put their hearing at risk. The conditions specified for the operation of the machines during the measurements are defined to provide a realistic and repeatable assessment of the maximum noise an operator should be subjected to when operating a machine. The test procedures specified in this International Standard are survey methods as defined in ISO 12001.
