本文件提供了ISO 6165中定义的土方机械（EMM）通用功能和类型所需机器性能水平（MPLr）的标准表。然后，这些MPLr可以映射或应用于用于控制或影响表中定义的功能的安全控制系统（SCS）。 本文件中的MPLr通过ISO 19014-1中概述的机器控制系统安全分析（MCSSA）过程确定。本文简要解释了如何得出这些水平以及相关假设。 本文件不适用于在其发布日期之前生产的EMM。

This document provides normative tables of machine performance levels required (MPL_r) by common function and type for earth-moving machinery (EMM) as defined in ISO 6165. These MPL_r can then be mapped or applied to safety control systems (SCS) used to control or that affect the functions defined in the table. The MPL_r in this document are determined through the machine control system safety analysis (MCSSA) process outlined in ISO 19014-1. A brief explanation of how the levels were derived and the associated assumptions are contained herein. This document is not applicable to EMM manufactured before the date of its publication.
