Overview

SIST EN 2040:2017 is a European Standard developed by CEN and the Aerospace and Defence Industries Association of Europe (ASD-STAN). It specifies the dimensions, tolerances, and physical constants for rolled rectangular steel bars used specifically in aerospace construction. This standard ensures consistency and quality for steel bars applied in critical aerospace components where precision and reliability are paramount.

The document defines tolerance class js16 for dimensional accuracy, covering a range of widths and thicknesses. It also provides guidelines for material properties, designation, and marking of products conforming to the standard.

Key Topics

• Dimensions and Tolerances:
  Defines nominal sizes and dimensional tolerance limits for rectangular steel bars, emphasizing tolerance js16. Tolerances vary according to material thickness and width, with detailed tables specifying permissible deviations in millimeters.

• Material Specifications:
  References related material standards, such as EN 2030 for Steel X105CrMo17, ensuring steel composition and treatment meet aerospace-grade requirements.

• Physical Constants:
  Provides mass per unit length values (kg/m), calculated based on steel density, facilitating engineering calculations and logistics.

• Designation and Marking:
  Describes the standardized format for product identification, including material standard number, dimensions or dimension codes, and the dimensional standard number (EN 2040). Marking requirements comply with technical product specifications.

• Scope and Application:
  Applies exclusively to rolled rectangular steel bars used in aerospace manufacturing, supporting safety and performance standards in aerospace assemblies.

Applications

• Aerospace Manufacturing:
  SIST EN 2040:2017 steel bars are used in aircraft and spacecraft structures, offering precise dimensional control vital for component fitting and structural integrity.

• Defense Industry:
  Suitable for defense aerospace projects requiring compliant steel parts with guaranteed tolerances, aiding in consistent assembly and quality assurance.

• Engineering and Design:
  Enables engineers to select materials with verified dimensions and tolerances, simplifying design validation and reducing components' rejection rates.

• Quality Control and Inspection:
  Provides a standardized benchmark for inspecting rolled steel bars to confirm compliance with aerospace specifications, ensuring traceability and reliability.

Related Standards

• EN 2030: Aerospace series - Steel X105CrMo17 bars - Material and heat treatment specifications. Closely linked to EN 2040 for material compliance.

• EN 4700: Aerospace series - Steel and heat resisting alloy wrought products - Technical specification, which complements EN 2040 marking and manufacturing requirements.

• ISO 286: Geometrical product specifications (GPS) - ISO code system for tolerances on linear sizes. Provides international guidelines on tolerance classes, including js16 used in EN 2040.

• Other Aerospace Series Standards: Related documents defining standards for various aerospace materials and semi-finished products, enabling comprehensive quality and engineering controls.

---

SIST EN 2040:2017 plays a crucial role in establishing uniformity and high quality in aerospace-grade rolled steel bars, supporting advanced manufacturing and stringent regulatory requirements in the aerospace sector. Its focus on detailed dimensions and tolerance js16 ensures components meet the demanding precision standards necessary for safe and efficient aerospace structures.
