SIST EN 2319:2018

Overview

SIST EN 2319:2018 is a European standard developed by CEN in the Aerospace series, specifying the requirements for aluminium alloy 2024- in the T3510 temper, supplied as drawn bar with a thickness (a) less than or equal to 75 mm. This standard is vital for aerospace manufacturers and suppliers who require high-performance aluminium bar products for demanding aerospace applications, ensuring consistent quality across European and international markets.

By adhering to SIST EN 2319:2018, organizations guarantee that the drawn aluminium bars meet a defined set of mechanical properties, chemical composition, and manufacturing processes, supporting safety and reliability in aerospace structures.

Key Topics

• Material Specification: Defines the chemical composition for aluminium alloy 2024-, including specific limits for alloying elements and impurities, ensuring material uniformity.
• Delivery Condition: Specifies that bars must be delivered in the T3510 temper, which involves solution heat treatment, controlled stretching, and natural aging to achieve desirable mechanical properties.
• Production Method: Covers the requirements for drawn aluminium bar production methods, with maximum permitted dimension (a ≤ 75 mm).
• Technical References: Mandates use of related standards (EN 2070-1, EN 2070-3, and EN 2044 to EN 2046) for technical specifications, tolerances, and dimensions.
• Inspection and Marking: Includes requirements for marking, dimensional inspection, and electrical conductivity testing per EN 2004-1 to verify quality compliance.

Applications

SIST EN 2319:2018 is specifically tailored for aerospace applications and is widely utilized in the production and supply chain of:

• Aircraft Structures: The high strength-to-weight ratio of aluminium alloy 2024- T3510 drawn bars makes them ideal for load-bearing components, frames, and structural supports in both commercial and military aircraft.
• Spacecraft Manufacturing: Ensures reliability and resilience in critical aerospace components exposed to extreme operating environments.
• Aerospace Fasteners and Connectors: Used as feedstock for precision-machined parts where mechanical integrity and stable properties are paramount.
• Aerospace and Defense Supply Chain: Guarantees consistency and interoperability when sourcing aluminium bar stock across national and international projects.

By standardizing material requirements, SIST EN 2319:2018 helps aerospace suppliers and OEMs reduce risk, lower costs related to rework or rejection, and maintain traceability throughout the product lifecycle.
