TS EN 4385

TS EN 4385 is a standard that defines the general organization of the EN standards used for non-metallic materials in aerospace applications and explains how these standard types relate to other standards. Its focus is not on the performance of one specific material, but on the structure of standardization itself: which documents set the general framework, which define material or product characteristics, and how those documents are linked across the aerospace field.

How the standard family is organised

As a framework standard, this document helps coordinate terminology, test methods and product specifications within the wider non-metallic materials domain. In aerospace, non-metallic materials can include polymers, composites, elastomers, adhesives, sealants and related material groups, so a clear organizational scheme helps avoid overlap and inconsistency between documents. The general technical value lies in making the standards system more traceable, easier to navigate and more coherent.

What the stated scope means in practice

The stated scope says that the document specifies the general organization of EN standards for non-metallic materials and their links with other types of standards for aerospace applications, and that it corresponds to level 0. In general technical terms, this indicates a top-level reference structure: more detailed material standards, test standards and application standards are positioned within a hierarchy. That makes it easier to identify which document is primary for a given material topic and which documents are supporting references.

• Covers the top-level organisation of the EN standard family for non-metallic materials.
• Describes links between different standard types used in aerospace applications.
• Is identified as a level 0 reference structure.
• Focuses on how standards are grouped and related, rather than on a single material specification.
