Overview

EN ISO 14405-3:2017 - "Geometrical product specifications (GPS) - Dimensional tolerancing - Part 3: Angular sizes" defines how to specify, tolerate and document angular dimensions in technical product specifications. Published by CEN and aligned with ISO 14405-3:2016, this standard provides the default specification operator for angular size and a set of special operators for common angular features such as cones (and frustums), wedges (and truncated wedges) and two opposite straight lines. It also standardizes drawing indications, specification modifiers, and how to express angular tolerances.

Key topics and requirements

  • Default and special specification operators: establishes the ISO default operator for angular size and special operators for revolute (cone/frustum) and prismatic (wedge) angular features.
  • Angular feature types: covers cones, frustums, wedges, truncated wedges and intersections that form two opposite straight lines.
  • Angular size characteristics: defines local and global angular sizes and specific measures including:
    • local angular size
    • angular size between two lines
    • portion angular size
    • direct global angular size (least squares, minimax)
    • rank order/indirect global angular sizes (maximum, minimum, average, range, mid-range, median, standard deviation)
  • Tolerance expression: permits +/− limit deviations (e.g., 0°/−0.5°), upper/lower limits (ULS/LLS, e.g., 35° max or 15° min, 34°/36°) and the use of modifiers.
  • Drawing indications and symbols: specifies graphical and text conventions for indicating angular sizes and their modifiers on engineering drawings.
  • Scope boundaries: provides tools to express angular characteristics but does not prescribe their relationship to function or intended use.

Practical applications

  • Use EN ISO 14405-3:2017 for consistent specification of angles in mechanical design, assemblies, precision components, and mould/tool design where angular tolerances affect fit and function.
  • Applicable to CAD/drafting, engineering drawing standards, metrology and inspection procedures, quality control, and production engineering.
  • Beneficial for manufacturers, design engineers, metrologists, quality managers and technical drafters who need unambiguous angular dimensioning and tolerance interpretation.

Who should use this standard

  • Mechanical and product designers, CAD specialists
  • Metrology and inspection teams implementing measurement procedures
  • Quality assurance and manufacturing engineers specifying tolerances
  • Standards committees and technical authors producing drawings and specifications

Related standards

  • ISO 14405-1 (Linear sizes)
  • ISO 14405-2 (Dimensions other than linear sizes)
  • ISO 8015 (GPS fundamentals)
  • ISO 17450 series (General GPS concepts and feature definitions)

Keywords: EN ISO 14405-3:2017, angular sizes, GPS, dimensional tolerancing, angular tolerances, cones, wedges, frustums, drawing indications, least squares, minimax, metrology.

Introduction
This part of ISO 14405 is a geometrical product specification (GPS) standard and is to be regarded as a
general GPS standard (see ISO 14638). In the general GPS matrix, it influences chain links “Symbols and
indications”, “Feature requirements” and “Feature properties” of the size chain of standards.
The ISO/GPS Masterplan given in ISO 14638 gives an overview of the ISO/GPS system of which this
part of ISO 14405 is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this part of
ISO 14405 and the default decision rules given in ISO 14253-1 apply to specifications made in accordance
with this part of ISO 14405, unless otherwise indicated.
For more detailed information on the relation of this part of ISO 14405 to other standards and to the
GPS matrix model, see Annex D.

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 also defines the specification modifiers and the drawing indications for these
angular sizes.
This part of ISO 14405 covers the following angular sizes:

— 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°,
ISO 14405-3:2016(E)
— 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.

angular size
angular dimension of a cone or between two coplanar opposite straight lines or between two opposite
non parallel planes
Note 1 to entry: The angular size is defined from nominal features or from associated features which are angular
features of size.
Note 2 to entry: See example of angular size on Figure 1 and Figure 2.
Note 3 to entry: Definition of “angular feature of size (feature of angular size)” is given in ISO 17450-1, the angle
dimension cannot be 0° or 180°.
Note 4 to entry: Angular features of size are of two types.
— Revolute angular feature of size: a cone or a frustum. Two opposite straight lines are established from
a longitudinal section of a cone/frustum with a plane containing the associated axis of revolution of the
cone/frustum.
— Prismatic angular feature of size: a wedge (truncated or not). Two opposite straight lines are established
from a cross section of a wedge/truncated wedge with a plane perpendicular to the intersection straight line
of the two associated planes of the wedge/truncated wedge.

Für die Anwendung dieses Dokuments gelten die Begriffe nach ISO 8015, ISO 17450-1, ISO 17450-2, ISO 17450-3, ISO 14405-1, ISO 14405-2 und die folgenden Begriffe. Es wird bei Assoziationskriterien davon ausgegangen, dass die Begriffe „der kleinsten Abweichungsquadrate“ und „Gauß“ sowie „Minimax“ und „Tschebyschew“ äquivalent sind. In diesem Dokument werden die Begriffe „der kleinsten Abweichungsquadrate“ und „Minimax“ beibehalten. Das Kriterium der kleinsten Abweichungsquadrate wird in diesem Gesamten Teil von ISO 14405 ohne Nebenbedingung des Materials verstanden. 3.1 Winkelgrößenmaß Winkelgrößenmaß eines Kegels oder zwischen zwei auf einer Ebene gegenüberliegenden Geraden oder zwischen zwei gegenüberliegenden nicht parallelen Ebenen Anmerkung 1 zum Begriff: Das Winkelgrößenmaß wird durch Nenngeometrieelemente oder assoziierte Geometrieelemente festgelegt, die Größenmaßelemente von Winkeln sind. Anmerkung 2 zum Begriff: Siehe Beispiel für Winkelgrößenmaß in Bild 1 und Bild 2. Anmerkung 3 zum Begriff: Die Definition für „Größenmaßelemente von Winkeln (Winkelgrößenmaßelemente)“ ist ISO 17450-1 zu entnehmen; das Winkelmaß kann weder 0° noch 180° betragen. Anmerkung 4 zum Begriff: Winkelgrößenmaßelemente werden in zwei Typen unterteilt. — Rotationssymmetrische Winkelgrößenmaßelemente: ein Kegel oder ein Kegelstumpf. Zwei gegenüberliegende Geraden werden durch einen Längsschnitt eines Kegels/Kegelstumpfes mit einer Ebene, die die assoziierte Rotationsachse des Kegels/Kegelstumpfes einschließt, festgelegt. — Prismatische Winkelgrößenmaßelemente: ein Keil (abgeschnitten oder nicht). Zwei gegenüberliegende Geraden werden durch einen Querschnitt eines Keils/abgeschnittenen Keils mit einer Ebene senkrecht zur Schnittgeraden der beiden assoziierten Ebenen des Kegels/Kegelstumpfes festgelegt. SIST EN ISO 14405-3:2017

Siehe auch Anhang B. Anmerkung 7 zum Begriff: Die Hüllbedingung ist nicht auf Winkelgrößenmaßelemente anwendbar.

Anmerkung 2 zum Begriff: In Bild 4 ist ein Beispiel für ein örtliches Winkelgrößenmaße dargestellt. Anmerkung 3 zum Begriff: Zwei örtliche Winkelgrößenmaßassoziationen können festgelegt werden: örtliches Winkelgrößenmaß der kleinsten Abweichungsquadrate und örtliches Minimax-Winkelgrößenmaß.

Anmerkung 2 zum Begriff: Der Prozess zur Festlegung des Zwei-Linien-Winkelgrößenmaßes ist von der Invarianzklasse des Geometrieelements abhängig: rotationssymmetrische oder prismatische Oberfläche. Anmerkung 3 zum Begriff: Der Default-Spezifikationsoperator, der das Zwei-Linien-Winkelgrößenmaß definiert, ist in Anhang A beschrieben. SIST EN ISO 14405-3:2017
