标准范围

本文件说明了使用尺寸规格来控制线性或角度尺寸以外的特性所造成的歧义,以及使用几何规格的好处。尺寸公差可以用±公差或几何规格表示。线性或角度尺寸以外的尺寸使用±公差引起的歧义(根据ISO 2768-1和ISO 8062,针对单个公差和一般公差-3) 附件A对此进行了解释。注1:如本文件所示,图中仅说明了文本,并不打算反映实际使用情况。因此,这些数字被简化为仅表示相关原则。注2:有关尺寸规格的指示,请参见以下内容:-线性尺寸的ISO 14405-1;-角度尺寸的ISO 14405-3;-适用于楔块的ISO 2538-1和ISO 2538-2;-ISO 3040适用于锥体。注3:ISO 1101中给出了几何规范的规则。

This document illustrates the ambiguity caused by the use of dimensional specifications to control properties other than linear or angular size and the benefit of using geometrical specifications instead.Dimensional tolerancing can be indicated by ± tolerancing or geometrical specifications.The ambiguity caused by using ± tolerances for dimensions other than linear or angular sizes (for individual tolerances and general tolerances according to, e.g. ISO 2768-1 and ISO 8062-3) is explained in Annex A.NOTE 1 The figures, as shown in this document, merely illustrate the text and are not intended to reflect actual usage. The figures are consequently simplified to indicate only the relevant principles.NOTE 2 For indications of dimensional specifications, see the following:— ISO 14405-1 for linear size;— ISO 14405-3 for angular size;— ISO 2538-1 and ISO 2538-2 for wedges;— ISO 3040 for cones.NOTE 3 The rules for geometrical specifications are given in ISO 1101.
