ISO 13715:2017规定了技术产品和尺寸中未定义边缘的指示和尺寸标注规则。还规定了要使用的图形符号的比例和尺寸。 如果需要几何定义的边缘形状（例如，1×45°），ISO 129-1中给出的一般尺寸标注原则适用。

ISO 13715:2017 specifies rules for the indication and dimensioning of undefined edges in technical product and dimensions. The proportions and dimensions of the graphical symbols to be used are also specified. In cases where the geometrically defined shape of an edge (for example, 1 × 45°) is required, the general dimensioning principles given in ISO 129？1 apply.
