前言

本文件按照GB/T1.1—2020《标准化工作导则第1部分：标准化文件的结构和起草规则》的规定

起草。

本文件是GB/T17889《梯子》的第4部分。GB/T17889已经发布了以下部分：

—第1部分：术语、型式和功能尺寸；

—第2部分：要求、试验和标志；

—第3部分：使用信息；

—第4部分：铰链梯；

—第5部分：伸缩梯；

—第6部分：可移动式平台梯。

本文件代替GB/T17889.4—2012《梯子第4部分：带有单个或多个铰链的梯子》，与

GB/T17889.4－2012相比，除结构调整和编辑性改动外，主要技术变化如下：

—将术语“纵向铰链梯子”更改为“铰链梯”并更改了定义（见3.1，2012年版的3.1）；

—将术语“带一个可锁定铰链接头装置的梯子”更改为“双铰链梯”，并增加了示例（见3.1.1，

2012年版的3.1.1）；

—将术语“带多个可锁紧铰链接头装置的梯子”更改为“多铰链梯”，并增加了示例（见3.1.2，

2012年版的3.1.2）；

—删除了术语“横向铰链梯子”及其定义（见2012年版的3.2）；

—更改了功能尺寸的一般要求（见4.1，2012年版的4.1）；

—删除了关于纵向铰链梯的要求（见2012年版的5.3）；

—更改了试验方法通则（见6.1，2012年版的6.1）；

—更改了铰链梯强度试验方法，并将梯子分为专业级梯和家用级梯（见6.2，2012年版的6.2）；

—增加了多铰链梯的附加强度试验（见6.3）；

—更改了台板件强度试验（见6.5.2，2012年版的6.2.4.2）；

—增加了用作平台时铰链梯及其台板件强度试验（见6.5.3）；

—删除了梯子安全试验（见2012年版的6.2.4.3）；

—删除了横向铰链梯的试验（见2012年版的6.3）；

—更改了使用说明书的要求（见第7章，2012年版的第8章）；

—删除了横向铰链梯的试验顺序（见2012年版的表A.2）。

引言

梯子是常用的一种登高类安全设施。GB/T17889旨在提高梯子相关产品的质量安全水平，保障使

用者安全，拟由6个部分构成。

—第1部分：术语、型式和功能尺寸。目的在于协调梯子相关的标准，给出梯子常用的术语、型

式，以及设计和测试等需要用到的影响梯子质量和安全水平的功能尺寸。

—第2部分：要求、试验和标志。目的在于保障梯子的安全水平，对影响梯子质量安全水平的因

素规定要求，并给出相应试验方法。

—第3部分：使用信息。目的在于确保使用者能按照标志指示和使用说明书正确使用梯子，对梯

子使用过程中起警示作用的标签，以及说明书中需要给出的信息和表述方式规定要求。

—第4部分：铰链梯。目的在于保障铰链梯的质量安全水平，对铰链梯规定特殊要求。

—第5部分：伸缩梯。目的在于保障伸缩梯的质量安全水平，对伸缩梯规定特殊要求。

—第6部分：可移动式平台梯。对可移动式平台梯规定特殊要求，目的在于保障可移动式平台梯

的质量安全水平。
