CEN/SS F01 - Technical drawings

This document specifies rules to identify specifications in the technical product documentation (TPD). It is applicable, if needed, to facilitate communication.

This document specifies how to uniquely identify the integral features of a part by an integral feature indicator with a unique alpha-numerical label and how indication in technical product documentation (TPD) is done, where needed to improve human readability.
The proportions and dimensions of graphical symbols for a simplified indication of repeated features are also specified.

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.

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.
