SIST EN 2146:2001

Overview

SIST EN 2146:2001 is a European standard from the CEN Aerospace series that defines the specifications for solid rivets with a universal head made from aluminium alloy 2017A. This standard focuses specifically on inch-based series rivets designed for aerospace applications. The rivets covered by SIST EN 2146:2001 are engineered to operate at a maximum temperature of 120 °C, ensuring performance reliability within typical aerospace environmental conditions.

This standard is essential for manufacturers, engineers, and quality assurance professionals involved in aerospace component assembly, providing a consistent framework for material properties, dimensions, and performance criteria of aluminium alloy rivets.

Key Topics

• Solid Rivets with Universal Head
  SIST EN 2146:2001 specifies rivets that are solid and feature a universal head design, suitable for a broad range of aerospace structural connections.

• Material: Aluminium Alloy 2017A
  The rivets are made from aluminium alloy 2017A, known for its favorable strength-to-weight ratio and corrosion resistance, critical for aerospace usage.

• Inch-Based Series Dimensions
  The standard applies inch-based series sizes, which align with aerospace industry preferences for inch measurement systems.

• Operating Temperature Limit
  Rivets conforming to this standard are rated for a maximum operating temperature of 120 °C, ensuring suitability for various aerospace environments.

• Dimensional and Mechanical Characteristics
  SIST EN 2146:2001 outlines precise geometric dimensions as well as mechanical property requirements that rivets must meet to ensure proper fit and structural integrity.
