工业自动化系统与集成 产品数据表示与交换 第47部分：集成通用资源：形状变化公差

[中文适用范围]： ISO 10303-47 规定了形状公差的集成资源构造。ISO 10303-47 的适用范围包括以下内容：作为产品形状特征约束的公差；对特定形状的公差进行规定；几何公差和正负公差的表示；公差值的表示；尺寸的表示；将尺寸特征分配给形状；将定位和定向特征分配给形状；通过引用基准建立的基准和基准系统的规定；识别派生形状元素，如中心线和交点；形状的极限与配合系统的结构。 [外文原描述]： ISO 10303-47 specifies the integrated resource constructs for Shape variation tolerances. The following are within the scope of ISO 10303-47: tolerances as constraints on the shape characteristics of a product; the specification of the tolerances on a defined shape; the representation of geometrical tolerances and plus-minus tolerances; the representation of tolerance values; the representation of dimensions; the assignment of size characteristics to a shape; the assignment of location and orientation characteristics to a shape; the specification of datums and datum systems that are established by referencing datums; the identification of derived shape elements such as centre lines and intersections; the structure for limit and fit systems for shapes.
