前言

本文件按照GB/T1.1—2020《標準化工作導(dǎo)則第1部分：標準化文件的結(jié)構(gòu)和起草規(guī)則》的規(guī)定

起草。

本文件是GB/T17889《梯子》的第4部分。GB/T17889已經(jīng)發(fā)布了以下部分：

—第1部分：術(shù)語、型式和功能尺寸；

—第2部分：要求、試驗和標志；

—第3部分：使用信息；

—第4部分：鉸鏈梯；

—第5部分：伸縮梯；

—第6部分：可移動式平臺梯。

本文件代替GB/T17889.4—2012《梯子第4部分：帶有單個或多個鉸鏈的梯子》，與

GB/T17889.4－2012相比，除結(jié)構(gòu)調(diào)整和編輯性改動外，主要技術(shù)變化如下：

—將術(shù)語“縱向鉸鏈梯子”更改為“鉸鏈梯”并更改了定義（見3.1，2012年版的3.1）；

—將術(shù)語“帶一個可鎖定鉸鏈接頭裝置的梯子”更改為“雙鉸鏈梯”，并增加了示例（見3.1.1，

2012年版的3.1.1）；

—將術(shù)語“帶多個可鎖緊鉸鏈接頭裝置的梯子”更改為“多鉸鏈梯”，并增加了示例（見3.1.2，

2012年版的3.1.2）；

—刪除了術(shù)語“橫向鉸鏈梯子”及其定義（見2012年版的3.2）；

—更改了功能尺寸的一般要求（見4.1，2012年版的4.1）；

—刪除了關(guān)于縱向鉸鏈梯的要求（見2012年版的5.3）；

—更改了試驗方法通則（見6.1，2012年版的6.1）；

—更改了鉸鏈梯強度試驗方法，并將梯子分為專業(yè)級梯和家用級梯（見6.2，2012年版的6.2）；

—增加了多鉸鏈梯的附加強度試驗（見6.3）；

—更改了臺板件強度試驗（見6.5.2，2012年版的6.2.4.2）；

—增加了用作平臺時鉸鏈梯及其臺板件強度試驗（見6.5.3）；

—刪除了梯子安全試驗（見2012年版的6.2.4.3）；

—刪除了橫向鉸鏈梯的試驗（見2012年版的6.3）；

—更改了使用說明書的要求（見第7章，2012年版的第8章）；

—刪除了橫向鉸鏈梯的試驗順序（見2012年版的表A.2）。

引言

梯子是常用的一種登高類安全設(shè)施。GB/T17889旨在提高梯子相關(guān)產(chǎn)品的質(zhì)量安全水平，保障使

用者安全，擬由6個部分構(gòu)成。

—第1部分：術(shù)語、型式和功能尺寸。目的在于協(xié)調(diào)梯子相關(guān)的標準，給出梯子常用的術(shù)語、型

式，以及設(shè)計和測試等需要用到的影響梯子質(zhì)量和安全水平的功能尺寸。

—第2部分：要求、試驗和標志。目的在于保障梯子的安全水平，對影響梯子質(zhì)量安全水平的因

素規(guī)定要求，并給出相應(yīng)試驗方法。

—第3部分：使用信息。目的在于確保使用者能按照標志指示和使用說明書正確使用梯子，對梯

子使用過程中起警示作用的標簽，以及說明書中需要給出的信息和表述方式規(guī)定要求。

—第4部分：鉸鏈梯。目的在于保障鉸鏈梯的質(zhì)量安全水平，對鉸鏈梯規(guī)定特殊要求。

—第5部分：伸縮梯。目的在于保障伸縮梯的質(zhì)量安全水平，對伸縮梯規(guī)定特殊要求。

—第6部分：可移動式平臺梯。對可移動式平臺梯規(guī)定特殊要求，目的在于保障可移動式平臺梯

的質(zhì)量安全水平。
