This part of ISO 14405 establishes the default specification operator for angular size and defines a number of special specification operators for features of angular size: cone (truncated, i.e. frustum, or not), wedge (truncated or not), two opposite straight lines (intersection of a wedge/truncated wedge and a plane perpendicular to the intersection straight line of the two planes of the wedge/truncated wedge, intersection of a cone/frustum and a plane containing the axis of revolution of the cone/frustum). See Figure 1 and Figure 2.
This part of ISO 14405 provides a set of tools to express several types of angular size characteristics. It does not give any information on the relationship between a function or a use and an angular size characteristic.

ISO 14405-1:2010 provides a set of tools to express several types of size characteristics. It does not present any information on the relationship between a function or a use and a size characteristic.
ISO 14405-1:2016 provides a set of tools to express several types of size characteristic. It does not present any information on the relationship between a function or a use and a size characteristic.
WG12 looks after a number of standards relating to size such as the ISO 286 series for linear sizes and the ISO 14405 series on dimensional tolerancing (linear sizes, sizes other than linear sizes, and angular sizes).
This article presents the general standard ISO 14405-1 describing and defining tolerances of linear sizes. We do not intend to discuss every single aspect of this standard but try to focus on the contents the author considers relevant for the purpose of defining specifications, especially of creating drawings and interpreting them.
Although the title of ISO 14405-1 refers to linear sizes, the standard itself (its contents) talks about features of size. This wording reflects the terminology of geometric tolerancing of form and location. This specialist field introduced geometrical features a long time ago. 2ff7e9595c
