扭矩扳子检定规程

1范围

本规程适用于扭矩扳子、扭矩螺丝刀、其他结构形式的带有扭矩测量机构的拧紧计

量器具(含附件)的首次检定、后续检定和使用中检验。

2引用文献

GB/T15729-1995扭力扳手通用技术条件

ISO6789-1992螺纹紧固件(螺栓、螺钉及螺母)装配工具—手动扭矩工具—

要求与测试方法

3概述

3.1用途

扭矩扳子是一种带有扭矩测量机构的拧紧计量器具，它用于紧固螺栓和螺母，并能

测量出拧紧时的扭矩值。

3.2分类

扭矩扳子按所使用的动力源，一般分为手动、电动、气动和液压四大类;按制造、

测量原理一般分为示值式和预置式两种;示值式又可分为指针式和数字式;预置式又可

分为机械式和电子式。

4计量性能要求

示值相对误差、示值重复性、示值分辨力

扭矩扳子的扭矩示值相对误差、示值重复性和分辨力应符合表1要求。
