CEN/SS F01 - Technical drawings

This document specifies a framework for building systems for the classification of requirements. Such systems can be used to indicate requirements of special importance, and communicate them for production set-up, verification, audit, etc.
This document:
—     gives background information why such systems are useful in many areas of manufacturing;
—     can be referred to for the concept of classification of requirements;
—     functions as a framework for applying such systems in technical product documentation (TPD);
—     indicates the needed elements for a classification system;
—     supports with aspects in the choice of symbols for a classification system.
As a framework, this document does not give the details of a specific classification system. Instead, it functions as a basis for an organization-specific system which contains details such as notations and symbols, classification levels, assessment procedures, etc., including usage and interpretation in the TPD.
This document does not specify the contractual consequences of a classification (e.g. needed actions such as choice of tools, reliability index or process capability for a classification level) nor other references to standards or documents for handling classifications and nonconformity to requirements.

This document specifies a method for the classification of requirements based on severity and susceptibility. The classification method requires a system in line with the framework described in ISO 24096-1 to form a complete system.
This document:
—     gives guidance on the needed elements for a consistent evaluation of the severity over time, and supports a company business model and its brand image;
—     gives background to why additional parameters alongside severity are useful as a base for classification;
—     adds susceptibility as a viable parameter along with severity;
—     gives guidance on the methodology for classification requirements using severity and susceptibility.

The proportions of the symbols are based on the standard heights of lettering given in ISO 3098-1.

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 presents an index of the terms used in the ISO 128 series in English, French, German, Chinese, Russian and Japanese.

This document gives general rules for the execution of technical drawings (2D and 3D), as well as presenting the structure of the other parts of the ISO 128 series. This document is applicable to technical drawing in the fields of mechanical engineering, construction, architecture and shipbuilding.

ISO 129-1:2018 establishes the general principles for presentation of dimensions and associated tolerances that apply to 2D technical drawings in all disciplines and trades but which can also be applied to 3D applications.
ISO 129-1:2018 does not cover the application of dimensional tolerances and their meaning. See ISO 14405‑1 for tolerancing principles. This document can only be used to describe the nominal model of a drawing, not the non-ideal surface model (skin model) used for tolerancing purposes (for more information on tolerancing specifications, see the list of GPS standards listed as normative reference or as bibliography)
Considering the ISO 14405 series, the presentation of tolerance indication is unambiguous when it is applied to a dimension which is a size and ambiguous when the dimension is not a size.
All rules presented in this document are available for any type of drawing (see ISO 29845).
In addition, this document introduces the concept of property indicators, developed length, between, surface indicators, flag notes and textual instructions.
NOTE 1    All figures are shown in 2D views only.
NOTE 2    Additional information and details for construction engineering are given in ISO 6284.

ISO 13715:2017 specifies rules for the indication and dimensioning of undefined edges in technical product and dimensions. The proportions and dimensions of the graphical symbols to be used are also specified.

ISO 13567-2:2017 covers the organization and allocation of layers for CAD on construction projects for the purposes of communication and management.

ISO 13567-1:2017 establishes the general principles of layer structuring within CAD files. Layers are used to control visibility and to manage and communicate CAD file data. Layer names are used to represent this structure.
The principles are applicable to all parties involved in preparing and using technical documentation on computer systems. Although these principles are primarily for users, CAD system developers are expected to provide software tools capable of implementing and supporting ISO 13567-1:2017. An important use is also to structure data in component libraries produced by third parties.

ISO 3098-1:2015 specifies the general requirements for lettering, in accordance with the other parts of ISO 3098, to be used in technical product documentation (in particular on technical drawings). It includes basic conventions as well as rules for the application of lettering using the following techniques: free-hand lettering (by means of an underlaid "grid"); templates and manual lettering instruments; dry transfer systems; numerically controlled lettering and draughting systems.

ISO 10628-1:2014 specifies the classification, content, and representation of flow diagrams. In addition, it lays down drafting rules for flow diagrams for chemical and petrochemical industry.

a)    general features of springs;
b)    application of springs in machinery and engineering;
c)        layouts and nomenclature of springs;
d)        specification requirements;
e)        design and calculation;
f)          manufacturing and processing;
g)        testing and inspection.
