SIST EN 2590:2017

Overview

SIST EN 2590:2017 is a European standard that specifies the dimensions and tolerances for hot rolled steel sheets and plates, specifically intended for use in aerospace constructions. This standard, adopted by the Slovenian Institute for Standardization (SIST), supports aerospace industry stakeholders by establishing consistent requirements for key product characteristics. By adhering to this standard, manufacturers and suppliers can ensure compatibility, performance, and safety across aerospace applications involving steel materials.

Key Topics

• Material Scope: The standard covers a range of aerospace-quality steels referenced in associated EN standards, addressing both sheets and plates produced via hot rolling.
• Dimensions: It specifies permissible thicknesses for sheets (e.g., 1.2 mm up to 6 mm) and plates (e.g., 8 mm up to 15 mm). Mass per unit area is calculated based on standard steel density.
• Dimensional Tolerances: SIST EN 2590:2017 defines tight tolerances for thickness, width, and length to ensure precision. For example, thickness tolerances vary depending on steel strength and width, as measured a minimum distance from the edge.
• Geometric Accuracy: Squareness (diagonal difference), local straightness, and flatness are addressed through clear measurement methods and allowed deviations.
• Designation: The standard refers to EN 2600 for the systematic designation of metallic semi-finished products.

Applications

SIST EN 2590:2017 is crucial in the following aerospace industry activities:

• Aircraft Structural Components: Ensures that hot rolled steel sheets and plates meet exacting dimensional standards for fuselages, frames, brackets, and panels.
• Supplier Quality Assurance: Provides clear acceptance criteria for incoming steel materials, supporting reliable procurement and manufacturing workflows.
• Design and Engineering: Offers engineers consistent reference data for specifying sheet and plate dimensions in technical documentation and CAD models.
• Cross-Border Trade and Collaboration: Facilitates compatibility and interoperability among aerospace manufacturers and suppliers across Europe by harmonizing material specifications and tolerances.
