SIST EN 2599:2002

Overview

SIST EN 2599:2002 is a European standard developed by CEN specifying the precise dimensions and tolerances for strips made of aluminium and aluminium alloys designed specifically for aerospace applications. This standard applies to aluminium strips with thickness ranging from 0.25 mm to 3.2 mm, ensuring uniformity and quality critical in aerospace manufacturing. As part of the aerospace series of EN metallic material standards, SIST EN 2599:2002 provides essential guidelines to manufacturers and suppliers within the aerospace sector for standardized strip dimensions.

Key Topics

• Material Scope: Strips made of aluminium and aluminium alloys aimed at aerospace use
• Thickness Range: Strips with thicknesses between 0.25 mm and 3.2 mm
• Dimensions: Detailed nominal widths and corresponding masses per unit area
• Dimensional Tolerances: Strict tolerances specified for both thickness and width to guarantee product consistency
• Measurement Requirements: Thickness measurements must be taken at least 20 mm from the edge of the strip
• Standardization Context: Part of a series linking to other aerospace metallic material standards (see EN 4258 for general organization)

Applications

SIST EN 2599:2002 serves as a critical reference for:

• Aerospace manufacturers requiring high-precision aluminium strips for aircraft structural components, skin, and other assemblies
• Suppliers and distributors ensuring aluminium strips meet aerospace industry demands and quality standards
• Quality control and inspection teams applying defined dimensional tolerances for accurate acceptance or rejection decisions
• Design engineers selecting appropriate aluminium strips with reliable dimensional characteristics and mass properties
• Fabricators and assemblers who depend on uniform material dimensions to achieve exact fitting and optimal structural integrity in aerospace parts

The strict compliance with SIST EN 2599:2002 also supports interoperability and material traceability across the European aerospace supply chain, helping reduce manufacturing errors and improve safety standards.

Related Standards

• EN 4258: Provides the general organizational framework for aerospace metallic material standardization, linking the types of EN standards and their specific uses.
• Other EN aerospace series standards targeting aluminium and metallic materials for various aerospace structural and functional components.
• National implementations: SIST EN 2599:2002 is implemented as a national standard in EU member states like Germany, France, UK, Italy, Spain, among others, ensuring harmonized aerospace strip specifications across Europe.

Summary

SIST EN 2599:2002 is a fundamental standard for aerospace aluminium strips, covering thickness from 0.25 mm to 3.2 mm. It ensures that materials supplied to aerospace manufacturers meet stringent dimensional and tolerance requirements essential for high-performance and safety-critical aerospace components. Adoption of this standard enhances product quality, manufacturing consistency, and regulatory compliance across the aerospace sector.
