ISO 3040:2016规定了适用于锥形（直角圆锥体）的图形指示，以定义其尺寸或指定其公差。 为了本国际标准的目的，术语“锥形”仅涉及直角圆锥（通过与标称锥体的轴垂直的平面的任何交点是圆）。 注1:为简单起见，本国际标准仅表示截锥体。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本国际标准并不旨在防止使用其他尺寸和公差的方法

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.
