Aerospace series - LOTAR LOng-Term Archiving and Retrieval of digital technical product documentation such as 3D, CAD and PDM data - Part 100: Common concepts for long-term archiving and retrieval of 3D mechanical CAD information
Scope: This document specifies common fundamental concepts for long term archiving and retrieval of mechanical CAD information for elementary parts and assemblies. It details the “fundamentals and concepts” of EN 9300-003:2012 in the specific context of long-term archiving of CAD mechanical models.
Mechanical CAD information is divided into assembly structure and geometrical information, both including explicit and implicit geometrical representation, geometric dimensioning and tolerancing with form features.
The EN 9300-1XX series is organized as a sequence of parts, each building on the previous ones in a consistent way, each adding a level of complexity in the CAD data model. This includes the detailing of relationships between the essential information for the different types of CAD information covered by the EN 9300-1XX series.
As technology matures, additional parts will be released in order to support new requirements within the aerospace community.
1.2 In Scope
This document specifies:
- the fundamentals and concepts for long-term archiving and retrieval of 3D mechanical CAD information;
- the document structure of the EN 9300-1XX series, and the links between all these parts;
- the qualification methods for long-term preservation of archived mechanical CAD information; more specially, principles for the CAD validation properties and for verification of the quality of the CAD archived file;
- specifications for the preservation planning of archived CAD information;
- specific functions for administration and monitoring of CAD archived mechanical models;
- the definition of archive information packages for CAD data.
1.3 Out of scope
The following are out of scope for this part:
- long-term archiving of CAD 2D drawings;
- other CAD specialization disciplines, such as electrical harnesses, composite.

Aerospace series - Use of regrinds and recycled materials in thermoplastic parts
Scope: This document gives guidance on the use of regrinds and recycled materials for thermoplastic parts for aerospace use.
This document does not apply to reinforced thermoplastic materials, such as short fibre-reinforced plastics, due to their distinct processing characteristics, material degradation concerns, and stringent aerospace performance requirements.
The intended manufacturing processes for these virgin/regrind blends include standard thermoplastic methods such as injection moulding, extrusion, and blow moulding, among others as appropriate to the application.
