本SAE标准的目的是定义试验条件，描述要进行的试验，指定要获得的数据，显示公式和计算，定义术语，并建立统一的报告方法，以便根据本文件进行试验的各种品牌和型号拖拉机上获得的性能数据，无论在何处进行试验，都具有可比性。由于许多型号和类型的拖拉机可以配备各种特殊或可选设备，因此本标准的范围必须限于获取和报告最重要的广泛使用的性能数据。 按照第4节中概述的标准规范或第5节中概述的受限Coed进行的试验将满足本农业拖拉机试验规范的要求。本标准在技术上等同于OECD拖拉机试验代码c（87）53附件一和附件二。本手册旨在为OECD官方测试前拖拉机的开发和预测试提供指南。然而，它不是OECD测试站使用的官方代码的替代品，任何有关OECD官方测试的问题或冲突都应通过咨询巴黎OECD协调中心的OECD官方代码来解决。

The purpose of this SAE standard is to define test conditions, describe tests to be made, specify data to be obtained, show formulas and calculations, define terms, and establish a uniform method of reporting so that performance data obtained on various makes and models of tractors, tested in accordance with this document, will be comparable regardless of where the tests are made. Because of the availability of many tractor models and types that can be equipped with a variety of special or optional equipment, the scope of this standard must be limited to obtaining and reporting only the most significant of widely used performance data.Test performed to either the Standard Code as outline in section 4 or the Restricted Coed as outlined in Section 5 will satisfy requirements of this Agricultural Tractor Test Code.This standard is technically equivalent to the OECD Tractor test Code c(87)53, Annex I and Annex II. It is intended as a guide to development and pre-testing of tractors prior to official OECD testing. It is not, however, a replacement for the official codes used by OECD test stations, and any questions or conflicts concerning official OECD testing should be resolved by consulting the official OECD codes of the OECD coordinating center in Paris.
