TS EN ISO 24096-1

TS EN ISO 24096-1 is Part 1 of the standard that provides a framework for classifying requirements in technical product documentation (TPD). It focuses on creating a structure that helps identify requirements of special importance and communicate them clearly for activities such as production set-up, verification, and audit.

What requirement classification is for

In general technical practice, not every product requirement carries the same weight. Some requirements may be critical to fit, function, safety-related performance, surface condition, material behaviour, or verification outcomes, while others may be less sensitive. A classification system is used to mark those requirements that need special attention so they can be handled consistently across documentation and manufacturing workflows.

This standard takes a framework-level approach. It does not define one fixed classification scheme, one set of symbols, or a specific assessment method. Instead, it describes the elements a classification system needs and offers support for choosing suitable symbols, leaving the detailed notation, classification levels, interpretation rules, and organization-specific procedures to the system adopted by the user.

What this part covers and what it leaves open

• Provides a framework for systems that classify requirements.
• Supports the use and interpretation of classification within TPD.
• Identifies the elements needed in a classification system.
• Offers guidance relevant to symbol selection.
• Does not prescribe a specific notation, classification level structure, or assessment procedure.
• Does not define contractual consequences or external documents for handling classification and nonconformity.

As a result, the document is useful as a common conceptual basis for organizations that want a consistent way to flag important requirements in technical product documentation. Its practical value lies in helping design, manufacturing, inspection, and quality teams read the same requirement in the same way.
