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。

本文件为GB/T24630《产品几何技术规范（GPS）

平面度》的第2部分。GB/T24630已经发布

了以下部分：

—第1部分：词汇和参数；

—第2部分：规范操作集。

本文件代替GB/T24630.2—2009《产品几何技术规范（GPS）

平面度第2部分：规范操作

集》，与GB/T24630.2—2009相比，除结构调整和编辑性改动外，主要技术变化如下：

a）更改了范围的表述（见第1章，2009年版的第1章）；

b）将“触针针尖”更改为“测针针头”（见第4章，2009年版的第4章）。

本文件等同采用ISO12781﹘2：2011《产品几何技术规范（GPS）

平面度第2部分：规范操

作集》。

GB/T24630.2—2024/ISO12781﹘2:2011

引言

平面度是产品几何技术规范中常见的形状公差之一，也是评估产品几何形状精度的关键指标之一，

更是现代化生产制造过程中必不可少的技术要素之一。平面度作为几何误差中最基本的一项，对保证零

部件的精确定位和配合，提升产品的准确性和可靠性，优化制造流程有着重要的基础作用。精准的平面

度规范不仅能减少制造过程中的误差和损失，还能显著降低产品的故障率，延长产品使用寿命，让产品

更具竞争力。随着数字化测量技术和产品几何技术规范的发展，原标准中的相关定义与现行的国家

GPS标准不相称，技术要求落后于当前生产需求，不再能有效地规范和指导市场生产现状。修订后的标

准能够更好地规范和指导产品几何要素，为企业在设计、制造、检验等过程提供技术支持，牵引我国高

端装备制造业的发展。

GB/T24630旨在规定组成要素的平面度规范，由2个部分构成。

—第1部分：词汇和参数。目的在于界定单一组成要素平面度的术语和概念。

—第2部分：规范操作集。目的在于规定单一组成要素平面度的完整规范操作集。
