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:
— local angular size:
— angular size between two lines;
— portion angular size;
— global angular size:
— direct global angular size:
— least squares angular size;
— minimax angular size;
— rank order angular size/indirect global angular size:
— maximum angular size;
— minimum angular size;
— average angular size;
— range of angular sizes;
— mid-range angular size;
— median angular size;
— standard deviation of angular size.
This part of ISO 14405 defines the meaning of tolerances of angular sizes indicated as
— + and/or - limit deviations, e.g. 0°/-0,5°, or
— indicated with upper limit of size (ULS) and/or lower limit of size (LLS), e.g. 35° max. or 15° min., 34°/36°,
— with or without modifiers.
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.
