前言

本文件按照GB/T1.1—2020《標準化工作導則第1部分：標準化文件的結構和起草規則》的規

定起草。

本文件代替GB/T5974.1—2006《鋼絲繩用普通套環》和GB/T5974.2—2006《鋼絲繩用重型套

環》，與GB/T5974.1—2006和GB/T5974.2—2006相比，除結構調整和編輯性改動外，主要技術變化

如下：

——增加了術語和定義（見第3章）；

——增加了套環的型式分類（見4.1）；

——更改了普通套環和重型套環的型號表示方法（見4.3，GB/T5974.1—2006的3.2和GB/T5974.2—

2006的3.2）；

——更改了重型套環的材料適用規格（見表3，GB/T5974.2—2006的表2）；

——更改了重型套環的承載能力（見5.2.2，GB/T5974.2—2006的4.4）；

——增加了重型套環的疲勞性能（見5.3）；

——增加了重型套環的無損檢測要求（見5.5）；

——增加了套環承載能力試驗的試驗機要求（見6.3.1）；

——增加了重型套環的疲勞試驗（見6.4）；

——增加了重型套環的無損檢測方法（見6.5）；

——增加了套環的檢驗分類（見7.1）；

——增加了套環的檢驗項目（見表5）；

——更改了套環出廠檢驗的抽樣方法和判定原則（見7.2.2，GB/T5974.1—2006的表3和GB/T5974.2—

2006的表3）；

——增加了套環的型式檢驗（見7.3）。
