<p>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.</p>
<p>This part of ISO 14405 also defines the specification modifiers and the drawing indications for these angular sizes.</p>
<p>This part of ISO 14405 covers the following angular sizes:</p>
<p>— local angular size:</p>
<p style="padding-left: 40px;">— angular size between two lines;</p>
<p style="padding-left: 40px;">— portion angular size;</p>
<p>— global angular size:</p>
<p style="padding-left: 40px;">— direct global angular size:</p>
<p style="padding-left: 80px;">— least squares angular size;</p>
<p style="padding-left: 80px;">— minimax angular size;</p>
<p style="padding-left: 40px;">— rank order angular size/indirect global angular size:</p>
<p style="padding-left: 80px;">— maximum angular size;</p>
<p style="padding-left: 80px;">— minimum angular size;</p>
<p style="padding-left: 80px;">— average angular size;</p>
<p style="padding-left: 80px;">— range of angular sizes;</p>
<p style="padding-left: 80px;">— mid-range angular size;</p>
<p style="padding-left: 80px;">— median angular size;</p>
<p style="padding-left: 80px;">— standard deviation of angular size.</p>
<p style="padding-left: 40px;">This part of ISO 14405 defines the meaning of tolerances of angular sizes indicated as</p>
<p>— + and/or - limit deviations, e.g. 0°/-0,5°, or</p>
<p>— indicated with upper limit of size (ULS) and/or lower limit of size (LLS), e.g. 35° max. or 15° min., 34°/36°,</p>
<p>— with or without modifiers.</p>
<p>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.</p>
