This part of ISO 14405 establishes the default specification operator for angular size and defines a number of special specification operators for features of size with angular size: cone, frustum (truncated or not), wedge (truncated or not), two opposite straight lines (intersection of a wedge/truncated wedge and a plane perpendicular to the median plane of the wedge/truncated wedge, intersection of a cone/frustum and a plane containing the axis of revolution of the cone/frustum). See Figures 1 and 2.
This part of ISO 14405 also defines the specification modifiers and the drawing indications for these angular sizes.
This part of ISO 14405 covers the following angular sizes.
¾ðLocal angular size;
¾ðAngular size between two lines;
¾ðPortion angular size.
¾ðGlobal angular size;
¾ðDirect global angular size;
¾ðLeast squares angular size;
¾ðMinimax angular size.
¾ðRank order angular size /indirect global angular size;
¾ðMaximum angular size;
¾ðMinimum angular size;
¾ðAverage angular size;
¾ðRange of angular size;
¾ðMid range angular size;
¾ðMedian angular size;
¾ðStandard deviation of angular size.
This part of ISO 14405 defines the meaning of tolerances of angular sizes indicated as:
¾ð+ and/or limit deviations, e.g. 0°/-0,5°, or;
¾ðindicated with upper limit of size (ULS) and/or lower limit of size (LLS), e.g., 35° max. or 15° min., 34°/36°;
¾ðwith or without modifiers.
This standard gives a set of tools, to express several types of angular size characteristic. It does not give any information on the relationship between a function or a use and an angular size characteristic.
