标准范围

本文件建立了适用于图案规范的ISO 1101补充规则，并定义了结合各个几何规范的规则，例如使用符号位置、对称性、线条轮廓和表面轮廓，以及附录C中列出的直线度（在被测特征名义上同轴的情况下）和平面度（在被测特征名义上共面的情况下）。当通过使用CZ、CZR或SIM修改器将一组公差带与位置或方向约束组合在一起时，这些规则适用。本文件不包括应用最小和最大材料要求时的图案规范的使用（见ISO 2692）。本文件不包括基于图案特征建立通用基准（见ISO 5459）。

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.
