SIST EN 2134:2004

Overview

SIST EN 2134:2004 is an international standard that defines the dimensions and tolerances for extruded round bars made from aluminium and aluminium alloys, specifically with diameters ranging from 10 mm to 220 mm. Published by the Slovenian Institute for Standardization (SIST), this standard is aligned with EN 2134:2001 and forms part of the broader European standards for aerospace metallic materials. Its primary focus is on products intended for the demanding requirements of aerospace applications, ensuring precision and reliability in manufacturing and engineering processes.

Key Topics

• Scope: This standard covers extruded round bars in aluminium and aluminium alloys, with strict dimensional limits between 10 mm and 220 mm in diameter.
• Dimensional Tolerances: Detailed ranges for diameter, length, straightness, and roundness deviations are specified, facilitating consistent quality across aerospace projects.
• Measurement Methods: The standard references established procedures for assessing form deviations and geometric tolerances vital for aerospace manufacturing.
• Supply Lengths: Provisions are made for both fixed and random bar lengths, with minimum and maximum lengths to be agreed upon at the time of order.

Applications

SIST EN 2134:2004 is essential for organizations involved in the aerospace sector and related industries where high-performance, reliable aluminium components are required. Key uses include:

• Aerospace Manufacturing: Ensures that aluminium round bars used in airframe structures, engine components, and systems meet strict dimensional and tolerance requirements.
• Quality Assurance: Provides a common reference for engineers, suppliers, and quality managers to verify compliance and traceability of material specifications.
• Procurement and Supply Chain: Helps buyers and suppliers establish clear criteria for aluminium bar procurement, aiding in contract definition and minimizing ambiguities.
• Precision Engineering: Supports secondary processes such as machining and forming, where precise dimensional tolerances are critical to final product performance.

By adhering to this standard, manufacturers guarantee the mechanical integrity and compatibility of aluminium components within sophisticated aerospace assemblies.
