This document describes the framework for building a system for classification of requirements. Such a system can be used to indicate requirements of special importance, and communicate them for production set-up, verification, and audit etc.
This document
— gives background information why such a system is useful in many areas of manufacturing;
— can be referred to for the concept of classification of requirements;
— functions as a framework for applying such a system 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 the details such as notations and symbols, classification levels, assessment procedures etc., including usage and interpretation in the TPD.
This document does not describe contractual consequences of a classification e.g., required actions like choice of tools, reliability index or process capability for a classification level, nor needed references to
other such standards or documents for handling classifications and non-conformity to requirements.

This document describes a method for classification of requirements based on severity and susceptibility. This classification method needs a system in line with the framework described in ISO 24096-1 to form a complete system. This document
— indicates 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 more than severity is useful as a base for classification;
— adds susceptibility as a viable parameter along with severity;
— describes the methodology for classification requirements using severity and susceptibility.
