产品几何量技术规范(GPS).几何公差.图案与组合几何规范

[中文适用范围]： 本文件建立了 ISO 1101 的补充规则，应用于图案规范，并定义了组合各个规范的规则，对于几何规范，例如使用符号位置、对称、线轮廓和表面轮廓，以及直线度（在公差的情况下）附件 C 中列出的公差特征名义上是同轴的）和平面度（在公差特征名义上共面的情况下）。 当通过使用 CZ 将一组公差带与位置或方向约束分组在一起时，这些规则适用， CZR 或 SIM 修饰符。 本文件不涵盖应用最小和最大材料要求时图案规范的使用（参见 ISO 2692）。 本文件不涉及基于图案特征的通用基准的建立（参见ISO 5459）。 [外文原描述]： This document establishes complementary rules to ISO 1101 to be applied to pattern specifications and defines rules to combine individual specifications, for geometrical specifications e.g. using the symbols POSITION, SYMMETRY, LINE PROFILE and SURFACE PROFILE, as well as STRAIGHTNESS (in the case where the toleranced features are nominally coaxial) and FLATNESS (in the case where the toleranced features are nominally coplanar) as listed in Annex C. These rules apply when a set of tolerance zones are grouped together with location or orientation constraints, through the use of the CZ, CZR or SIM modifiers. This document does not cover the use of the pattern specifications when the least and maximum material requirement is applied (see ISO 2692). This document does not cover the establishment of common datum (see ISO 5459) based on pattern features.
