Overview

SIST EN 683-2:2024 is a European standard developed by CEN specifying the mechanical properties of wrought aluminium and aluminium alloy finstock. This document replaces the previous EN 683-2:2006 version and aligns with modern testing procedures and product specifications. It defines key mechanical characteristics such as yield strength, tensile strength, and elongation for various aluminium alloys and tempers, primarily used in heat exchanger applications. The chemical composition limits adhere to EN 573-3, and temper designations follow EN 515.

This standard is critical for manufacturers, suppliers, and purchasers involved with aluminium finstock products, ensuring consistent quality, performance, and safety across Europe and beyond.

Key Topics

• Scope of Mechanical Properties
  SIST EN 683-2:2024 outlines the mechanical limits for aluminium finstock in different tempers including H14, H16, H18, H19, O, H22, and H24. Specified properties include:

  • Yield strength (Rp0.2)
  • Tensile strength (Rm)
  • Elongation at fracture (A or n)
    These are detailed for various alloys such as EN AW-1050A, EN AW-1100, EN AW-3003, EN AW-6063, and newly included EN AW-5052.

• Tensile Testing Methods
  Testing must comply with EN ISO 6892-1, focusing on room temperature tensile tests. Test specimens are described precisely, including parallell-sided or shouldered shapes and specific dimensions for width, gauge length, and thickness ranges (60 μm to 400 μm). Procedures detail strain rates and methods for measuring elongation, especially for thin finstock.

• Rounding Rules for Test Results
  Annex A provides specific rules for rounding mechanical test results to ensure uniform reporting and interpretation across laboratories and suppliers.

• Reference to Related Standards
  SIST EN 683-2:2024 incorporates references to:

  • EN 573-3: Chemical composition and form of wrought aluminium alloys
  • EN 515: Temper designations for wrought aluminium
  • EN ISO 6892-1: Tensile testing at room temperature
  • EN 683-1: Technical conditions for inspection and delivery of finstock

Applications

• Heat Exchanger Manufacturing
  Aluminium finstock is widely used in thermal exchange equipment such as radiators, condensers, and evaporators where mechanical properties directly impact durability and heat transfer efficiency.

• Automotive Industry
  Components such as cooling systems and air conditioning units often rely on aluminium finstock specified by SIST EN 683-2:2024 for performance under thermal and mechanical stress.

• Construction and HVAC
  Aluminium finstock complying with this standard assures structural integrity and longevity in heating, ventilation, and air conditioning units exposed to varying operational conditions.

• Quality Control and Compliance
  Suppliers utilize SIST EN 683-2:2024 to certify that finstock meets consistent mechanical criteria required by purchasers or regulatory bodies, facilitating international trade and standardization.
