This document establishes rules for the simplified representation of threaded parts, with the exception of screw thread inserts, which are covered in ISO 6410-2. This representation is applicable when it is not necessary to show the exact shape and details of the parts (see ISO 6410-1), for example in assembly drawings.

This document specifies the requirements for a digital mock-up virtual assembly test (VAT) for mechanical products, which is suitable for guiding virtual assembly testing before physical production. The application of this document is intended to result in an effective VAT and efficient on-site assembly. This test is applicable to 3D nominal models with theoretically exact dimensions.

This document establishes rules and conventions for particular use with technical drawings on glassware, for example, laboratory glassware or glassware used in other technical fields. Optical parts are not, however, included herein.

ISO 21600:2019 specifies the composition, basic principles, preparation process, general requirements, detailed requirements, publication and application requirements, and management requirements of mechanical product digital manuals. ISO 21600:2019 is intended to be used for guidance in the preparation of digital manuals, which provide guidance in the use, repair and maintenance of products. It is also intended to be used for reference in production and manufacturing. ISO 21600:2019 does not specify function or data structure of any specific software. ISO 21600:2019 applies to the preparation of mechanical product digital manuals based on service bills of material and modularized technical information.

This document specifies the rules and graphical symbols for the representations of splines and serrations in technical product documentation. Two methods of representation are specified: a) complete representation; b) simplified representation. The rules and graphical symbols specified in this document are applicable to detail drawings of parts (shafts and hubs) and to assembly drawings of joints. NOTE For uniformity, all the figures in this document have been drawn in the first-angle orthographic projection. A third-angle orthographic projection could equally have been used without prejudice to principles established.

ISO 129-4:2013 specifies the dimensioning for general use on metal hulls on shipbuilding drawings.

ISO 13444:2012 specifies a series of knurling dimensions intended for general use in mechanical engineering and is intended to avoid an unnecessary multiplicity of tools by restricting the profile angle to 90° and by restricting the selection of diametral pitches.

ISO 128-71:2010 specifies general principles and basic methods for the application of the simplified representation on mechanical engineering drawings.

Specifies the representation in front view of rivets on drawings for aerospace equipment.

Specifies a detailed simplified representation for various rolling bearings. Should be used in cases where it is not necessary to show the exact shape and details of the rolling bearings, for example in assembly drawings.

Gives rules for the simplified representation of compression, extension, torsion, disc, spiral and leaf springs on technical drawings.

Specifies methods for the representation: detailed representation of the true shape, conventional representation, simplified representation, designation and dimensioning.

Specifies methods for representation in general: detailed representation, conventional representation, assembled threaded parts, designation and dimensioning, indication of direction of lead.

The principle of the drawing method in this part is that only essential features are shown, preferably in outline. The degree of simplification depends on the kind of object represented, the scale of the drawing and the purpose of the documentation. Part 2 deals with the detailed simplified representation.

In contrast to the general simplified representation of part 1, this method shows more details of a seal, for example the configuration of lips. It should also be used when it is not necessary to show the exact shape and details of the seals, for example in assembly drawings. Elements and examples of this representation mode are given in tables and figures.

This method indicates only essential features ans should be used when it is not necessary to show the exact shape and details of the seals, for example in assembly drawings. The degree of simplification depends on the kind of object represented, the scale of the drawing and the purpose of documentation. ISO 9222-2 deals with the detailed simplified representation.

The symbols system is intended for simplifying the preparation of diagrams of products in all branches of industry and is to be used in technical documentation as well as in technical and educational literature. It will facilitate the execution and understanding of such diagrams by specialists of different countries. This part contains miscellaneous mechanisms and their components.

This representation mode may be used particulary when it is not necessary to show the exact form and size and where the designation of standardized centre holes is sufficient for information. Annex A gives the dimensions for types R, A and B, and Annex B the proportions and dimensions of symbols.

The symbols system is intended for simplifying the preparation of diagrams of products in all branches of industry and is to be used in technical documentation as well as in technical and educational literature. This part contains the following: Motion of links of mechanisms, kinematic pairs, links and connections of their components, and N-bar linkages and their components.

The symbols system is intended for simplifying the preparation of diagrams of products in all branches of industry and is to be used in technical documentation as well as in technical and educational literature. It will facilitate the execution and understanding of such diagrams by specialists of different countries. This part contains friction and gear mechanisms and cam mechanisms.

The symbols system is intended for simplifying the preparation of diagrams of products in all branches of industry and is to be used in technical documentation as well as in technical and educational literature. It will facilitate the execution and understanding of such diagrams by specialists of different countries. This part contains Geneva and ratchet mechanisms as well as couplings and brakes.

Establishes how to draw the toothed portion of gears including worm gearing and chain wheels. Applicable to detail drawings (individual gears) and assembly drawings (gear pairs). As a fundamental principle a gear is represented (except in axial section) as a solid part without teeth, but with the addition of the pitch surface in a thin long dash-and-dot line. For uniformity all figures are in first angle projection.

ISO 128-24:2014 specifies general rules and basic conventions for the types of lines on mechanical engineering drawings.

This part of ISO 128 specifies rules for the presentation of views additional to those of ISO 128-30 and applicable to mechanical engineering drawings that follow the orthographic projection methods specified in ISO 5456-2. Attention has also been given to reproduction requirements, including those of microcopying according to ISO 6428.

Annex A gives proportions and dimensions of the symbols, annex B gives synoptic tables, annex D includes examples.

The figures merely illustrate the text and should not be considered design examples. They are simplified and not to ecale.
