Scope

本标准定义了关于几何规范、特征和条件的一般术语。这些定义是基于GB/T 24637.1和GB/T 38760中的概念，以及GB/T 24637.1-2020附录B中的数学描述。
本标准不仅仅适用于工业应用领域，而且可以作为理解和规划几何特征要求的“路线图”，从而使工业和软件制造商在标准化上得到统一。
本标准定义了几何特征和条件的基本类型，这些描述适用于以下的情况：
——一个工件；
——一个装配件；
——一批工件；
——一批装配件。
这些定义基于GB/T 24637.1和 GB/T 24637.2中的操作集的概念和对偶性原理，以及由GB/T 38760中的几何特征类型的描述。
从概念上讲，这些规范操作可用作规范操作集或检验操作集（对偶性原理）。
本标准不旨在于定义GPS规范、符号或其他类型的表述。
