前言

本标准是首次制定

本标准修改采用ISO1211711997《土方机械小m挖掘机倾翻保护结构的试验室试验和性能要

求》(英文版)，包括其200。年12月1日出版的技术勘误1,

本标准根据ISO12117;1997重新起草。

本标准与ISO1211711997的技术差异如下

a)对规范性引用文件:

-ISO12117:1997中引用了两个将要出版的ISO标准，现本标准的引用改为采用国际标准

现行版本的我国国家标准;GB/T8498-1999《土方机械基本类f术语》(eqv1SC

6165;1997)和GB/T19932-2005土《方机械液压挖掘机司机防护装置的试验室试验

和性能要求》(ISO10262;1998,MOD)，本标准相应删除了ISO12117:1997中关于版本

说明的脚注1)和脚注2);

-ISO12117:1997中引用的是ISO898-1;1988，现本标准的引用改为采用ISO898-1:1999

的GB/T3098.1-2000((紧固件机械性能螺栓、螺钉和螺柱》。

b)删除了ISO12117:1997中7.2中的注“注:采用英制的国家，应采用相同性能级别的螺栓和

螺母。”。

为了便于使用.本标准还做了一些编辑性修改:

—“本国际标准”一词改为“本标准”;

—用小数点“.”代替作为小数点的“，”;

—删除了国际标准的前言‘

本标准的附录A是规范性附录，附录B是资料性附录。

本标准由中国机械工业联合会提出。

本标准由机械工业工程机械标准化技术委员会归口。

本标准负责起草单位:天津工程机械研究院。

本标准参加起草单位;广西柳工机械股份有限公司、三一重工股份有限公司。
