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.
