EN 2544:1987

Overview

EN 2544:1987 (CEN) - Aerospace series - Representation of rivets on drawings for aerospace equipment - is a European standard that specifies how rivets should be represented on technical drawings used in the aerospace sector. The standard establishes uniform drawing conventions to ensure clear communication of rivet types, locations and intent across designers, manufacturers, suppliers and regulatory bodies.

Key Topics

While the full text contains the authoritative requirements, this standard focuses on the following core areas related to the representation of rivets on aerospace drawings:

• Graphical representation and symbols for rivets to ensure consistent depiction across engineering drawings and CAD outputs.
• Annotation and labeling conventions that identify rivet type, size class and any special installation notes.
• Views and projection rules for showing rivets in plan, section and detail views so that joint configuration and stack-ups are unambiguous.
• Drawing conventions for holes and edge conditions where rivets pass through structural elements (e.g., alignment of holes, countersinks or counterbores) to aid manufacturing and inspection.
• Information transfer best practices to ensure rivet-related data (location, spacing, pitch, and special requirements) are recorded clearly for production and quality control.

Applications

EN 2544:1987 is practical for professionals involved in the lifecycle of aerospace structures and equipment:

• Aerospace design engineers preparing structural assembly drawings and rivet schedules.
• CAD/drafting teams producing consistent technical drawings and library symbols for rivets.
• Manufacturing and assembly personnel who rely on clear drawing representation to install rivets correctly.
• Quality, inspection and certification teams that verify riveted joints against drawing intent.
• Suppliers and subcontractors who need unambiguous drawing information for fabrication and procurement.

Adoption of EN 2544 helps reduce interpretation errors, speeds up communication between stakeholders, and supports conformity to aerospace drawing practices.
