标准范围

ISO 25378:2011定义了几何规格、特性和条件的通用术语。这些定义基于ISO 17450-1和ISO 22432中开发的概念，并通过使用基于ISO 17450-1:20 11附录B的数学描述给出。ISO 25378:2011并不打算供设计师工业使用，而是旨在作为基于几何特征绘制需求的“路线图”，从而以一致的方式为行业和软件制造商实现未来的标准化。ISO 25378:2011定义了可用于GPS的几何特征和条件的一般类型。这些描述适用于工件，组件，工件群体，以及一组程序集。这些定义基于ISO 17450中包含的算子概念和对偶原则-1和ISO/TS 17450-2以及ISO 22432中定义的几何特征类型的描述。从概念上讲，这些规范运算符可以用作规范运算符，也可以用作验证运算符（对偶原则）。ISO 25378:2011无意定义GPS规范、符号或其他类型的表达。

ISO 25378:2011 defines general terms for geometrical specifications, characteristics and conditions. These definitions are based on concepts developed in ISO 17450-1 and ISO 22432 and they are given by using a mathematical description based on Annex B of ISO 17450-1:2011.ISO 25378:2011 is not intended for industrial use as such among designers, but is aimed to serve as the "road map" mapping out the requirements based on geometrical features, thus enabling future standardization for industry and software makers in a consistent manner.ISO 25378:2011 defines general types of geometrical characteristics and conditions which can be used in GPS. These descriptions are applicable to

• a workpiece,
• an assembly,
• a population of workpieces, and
• a population of assemblies.

These definitions are based on concepts of operators and the duality principle contained in ISO 17450-1 and ISO/TS 17450-2 and on the description of types of geometrical features defined in ISO 22432.Conceptually, these specification operators can be used as specification operators or as verification operators (duality principle).ISO 25378:2011 is not intended to define GPS specifications, symbology or other types of expression.
