Overview

EN 2851:1992 - "Aerospace series - Marking of parts and assemblies other than engines - Indications on drawings" is a CEN standard that defines the method for indicating, on engineering drawings, the instructions required for marking of parts and assemblies used in aerospace applications. The standard applies to aerospace drawings except those for engines. EN 2851:1992 was later adopted by the Slovenian Institute for Standardization as SIST EN 2851:2001.

Key topics and requirements

EN 2851:1992 concentrates on how marking instructions should be represented on technical drawings to ensure consistent interpretation across design, manufacture and maintenance. Key topics covered by the standard include:

• Method of indication on drawings for marking requirements (how marking instructions are shown and referenced).
• Scope limitation explicitly excluding engine drawings; applies to parts and assemblies in the rest of the aerospace product.
• Consistency and clarity of drawing notes so marking instructions are unambiguous for suppliers and production.
• Traceability and identification instructions to support part identification, quality control and lifecycle management.
• Conventions for placement and referencing of marking notes on mechanical and aerospace drawings to avoid misinterpretation.

(EN 2851:1992 specifies the drawing-level conventions rather than prescribing particular marking processes or technologies.)

Applications

This standard is practical for organizations and functions that create, interpret or act on aerospace engineering drawings, including:

• Aerospace design and engineering teams preparing assembly and part drawings.
• Drafting and CAD departments establishing drawing templates and note conventions.
• Suppliers and manufacturers implementing marking instructions during production.
• Quality assurance, inspection and traceability teams verifying that parts carry required identification.
• Maintenance, repair and overhaul (MRO) organizations interpreting marking notes for in-service items.

Using EN 2851:1992 helps maintain consistent aerospace marking practices across the supply chain, reducing errors and improving part traceability.

Related standards

EN 2851:1992 sits within the broader set of CEN and international standards for technical drawings, part identification and traceability. Organizations typically apply it alongside other drawing standards and aerospace-specific marking or serialisation guidance to create a complete marking and documentation system.
