ISO 3040:2016规定了适用于圆锥体（直角圆锥体）的图形指示，以定义其尺寸或规定其公差。 在本国际标准中，术语“圆锥体”仅与直角圆锥体有关（与标称圆锥体轴线垂直的平面的任何交点都是圆）。 注1:为简单起见，本国际标准中仅表示截锥。然而，本国际标准可适用于其范围内的任何类型的锥体。 注2:本国际标准无意阻止使用其他尺寸标注和公差标注方法。

ISO 3040:2016 specifies graphical indication applicable to a cone (right-angle circular cones) to define its dimensioning or to specify its tolerancing. For the purposes of this International Standard, the term "cone" relates to right-angle circular cones only (any intersection by a plane perpendicular to the axis of the nominal cone is a circle). NOTE 1 For simplicity, only truncated cones have been represented in this International Standard. However, this International Standard can be applied to any type of cone within its scope. NOTE 2 This International Standard is not intended to prevent the use of other methods of dimensioning and tolerancing.
