标准范围

ISO 129-1:2018确立了尺寸和相关公差表示的一般原则，适用于所有专业和行业的2D技术图纸，但也适用于3D应用。ISO 129-1:2018未涵盖尺寸公差的应用及其含义。公差原则见ISO 14405-1。本文件只能用于描述图纸的标称模型，而不是用于公差标注目的的非理想表面模型（皮肤模型）（有关公差标注规范的更多信息，请参阅作为规范性参考或参考书目列出的GPS标准列表）考虑到ISO 14405系列，当公差表示应用于尺寸时，它是明确的，当尺寸不是尺寸时，它是模糊的。本文件中的所有规则适用于任何类型的图纸（见ISO 29845）。此外，本文件还介绍了属性指示器、展开长度、间距、表面指示器、旗帜注释和文字说明的概念。注1:所有图仅在二维视图中显示。注2:ISO 6284中给出了建筑工程的附加信息和细节。

ISO 129-1:2018 establishes the general principles for presentation of dimensions and associated tolerances that apply to 2D technical drawings in all disciplines and trades but which can also be applied to 3D applications.ISO 129-1:2018 does not cover the application of dimensional tolerances and their meaning. See ISO 14405？1 for tolerancing principles. This document can only be used to describe the nominal model of a drawing, not the non-ideal surface model (skin model) used for tolerancing purposes (for more information on tolerancing specifications, see the list of GPS standards listed as normative reference or as bibliography)Considering the ISO 14405 series, the presentation of tolerance indication is unambiguous when it is applied to a dimension which is a size and ambiguous when the dimension is not a size.All rules presented in this document are available for any type of drawing (see ISO 29845).In addition, this document introduces the concept of property indicators, developed length, between, surface indicators, flag notes and textual instructions.NOTE 1 All figures are shown in 2D views only.NOTE 2 Additional information and details for construction engineering are given in ISO 6284.
