Overview

EN 2365:1989 - adopted as SIST EN 2365:2001 - is a CEN aerospace standard that specifies the characteristics of aluminium alloy collars intended for aerospace applications. The standard defines the required characteristics for these collars when used in conjunction with shear pins (EN 2364) and split pins (EN 2367). It applies to collars used as part of aircraft fastening and retention systems where compatibility with the referenced pins is critical.

Key topics

The standard focuses on the essential characteristics that ensure safe, reliable performance of aluminium alloy collars in aerospace assemblies. Key technical topics typically covered include:

• Material specification: designation of aluminium alloy(s) appropriate for collar manufacture and their suitability for aerospace use.
• Dimensional and geometric characteristics: features required for proper fit with mating shear pins and split pins to ensure mechanical compatibility.
• Interface and compatibility: requirements to ensure collars work reliably with EN 2364 (shear pins) and EN 2367 (split pins).
• Manufacturing and quality aspects: expectations around consistent production, inspection, and traceability appropriate to aerospace components.
• Marking and identification: means to mark collars for part identification, batch control, and conformity demonstration.

Note: EN 2365 defines characteristics rather than giving application-specific installation procedures or torque values.

Applications

This standard is relevant wherever aluminium alloy collars are used as part of aircraft fastener systems and retention arrangements. Typical practical applications include:

• Retention and shear protection assemblies in airframe and subsystem components.
• Mechanical joints where controlled failure (shear) is required for safety or serviceability.
• Replacement and maintenance of collars in aerospace repair and overhaul activities.

Who uses this standard:

• Aerospace component designers and engineers specifying fastener interfaces.
• Fastener and small-components manufacturers producing aluminium collars.
• Procurement and quality assurance teams verifying supplier conformance.
• Maintenance, repair and overhaul (MRO) organizations working with compatible shear and split-pin assemblies.
• Certification and compliance personnel ensuring components meet industry standards.
