SIST EN 2364:2001

Overview

SIST EN 2364:2001 specifies the characteristics for close tolerance headed shear pins manufactured from steel with cadmium plating, specifically designed for aerospace applications. These pins are engineered for use at temperatures below 235 °C and are integral components for precise and secure connections in demanding environments. Published by the Slovenian Institute for Standardization (SIST), this European Standard provides consistent guidelines for quality, safety, and performance in the aerospace sector.

Key Topics

• Pin Characteristics: Defines dimensions, material requirements, and mechanical properties of headed shear pins, ensuring compatibility and interchangeability across aerospace projects.
• Material Specification: Focuses on steel pins with cadmium plating, improving corrosion resistance and ensuring durability in various aeronautical conditions.
• Operating Temperature: Specifies usage below 235 °C, providing clarity for safe application and material longevity.
• Interconnection: Designed for use with compatible fasteners, specifically collars (EN 2365) and split pins (EN 2367), supporting robust and standardized assembly solutions.

Applications

Aerospace professionals rely on SIST EN 2364:2001 for:

• Aircraft Manufacturing: Ensuring reliable fastening in structural assemblies, such as wing sections, fuselage panels, and landing gear attachment points, where shear loads are critical.
• Maintenance and Repair: Specifying parts during repair or retrofitting to maintain compliance with international aerospace standards and guarantee continued airworthiness.
• Component Design: Assisting design engineers in selecting standardized connecting hardware, which streamlines the design process and reduces risk of component mismatch.
• Quality Assurance: Establishing clear benchmarks and inspection criteria for manufacturers and suppliers of aerospace fastening hardware, enhancing traceability and product consistency.

By adhering to this standard, aerospace engineers and manufacturers can achieve high levels of safety, performance, and interchangeability across complex systems. The specification of close tolerance shear pins plays a crucial role in supporting the structural integrity and reliability required for modern aerospace operations.
