本推荐规程定义了具有类似特性的拖拉机类别，这些特性会影响通过操作员座椅传递给操作员的振动。本推荐规程为农业轮式拖拉机的各种分类建立了进行操作员座椅振动试验的输入数据参数。该分类旨在帮助为特定拖拉机型号选择座椅，并减少确定是否符合适用标准和/或建议所需的测试量。分类基于基本结构和总质量。 SAE J1013 JAN80中规定了仪器和测量程序。SAE J1384中规定了试验程序。本文件符合1984年10月在西班牙马德里由ISO/TC23/SC3通过的dIS 5007。

This Recommended Practice defines classes of tractors having similar characteristics which affect the vibration transmitted to the operator through the operator seat. This recommended practice establishes input data parameters for conducting operator seat vibration tests for various classifications for agricultural wheeled tractors. The classification is intended to aid in the selection of a seat for a specific tractor model and to reduce the amount of testing necessary to determine compliance with applicable standards and/or recommendations. Classification is based on basic configuration and total mass. Instrumentation and measurement procedures are specified in SAE J1013 JAN80. Test procedures are defined in SAE J1384. This document is in compliance with dIS 5007 adopted by ISO/TC23/SC3 October 1984 in Madrid, Spain.
