TS EN 9300-100

TS EN 9300-100 defines the common concepts for the long-term archiving and retrieval of 3D mechanical CAD information in aerospace. Its focus is not a single file format, but the foundational approach needed to preserve mechanical CAD data reliably, validate it over time, and make it usable again when required.

Core building blocks of mechanical CAD information

In this part, mechanical CAD information is organized around two main areas: assembly structure and geometric information. The geometric content is understood in a framework that includes explicit and implicit geometric representation, geometric dimensioning and tolerancing, and form features. This distinction matters because long-term preservation is not only about storing shapes; it is also about keeping the meaning of the model, including how individual parts relate within an assembly.

Position within the EN 9300-1XX series

The standard carries forward the fundamentals and concepts of EN 9300-003:2012 into the specific context of long-term archiving of mechanical CAD models. It also explains the structure of the EN 9300-1XX series, where each part builds on the previous one and adds increasing complexity to the CAD data model. In practice, this makes TS EN 9300-100 a reference point for the shared terminology and relationship logic that supports the later parts of the series.

Archiving, validation and administration

• Fundamental concepts for long-term archiving and retrieval
• The document structure of the EN 9300-1XX series and the links between its parts
• Principles for preservation planning of archived CAD information
• Administration and monitoring functions for archived CAD models
• Definition of archive information packages for CAD data
• Principles for CAD validation properties and quality verification of archived files

In general technical terms, long-term archiving is more than storage: it is an information management approach designed to preserve readability, integrity and meaning over time. The exclusion of 2D drawings and other specializations such as electrical harnesses and composites shows that this part is focused specifically on 3D mechanical CAD information.
