Overview

SIST EN 2044:2004 is a European standard developed by CEN and AECMA, specifically targeting the aerospace industry. It sets precise specifications for the dimensions and tolerances of drawn round bars made of aluminium and aluminium alloys. This standard applies to bars with diameters ranging from over 4 mm up to 63 mm and follows tolerance class h11. SIST EN 2044:2004 ensures consistency and quality in metallic semi-finished products critical for aerospace manufacturing and engineering.

Key Topics

  • Material Type

    • Aluminium and aluminium alloys suitable for aerospace applications
    • Products: Drawn round bars

  • Dimensional Specifications

    • Diameter range: >4 mm to <63 mm
    • Tolerance Class: h11, defining permissible variations in dimensions to ensure fit and function

  • Mass and Length

    • Linear mass values are provided for different nominal diameters (density assumed as 2.8 kg/dm³)
    • Options for supplying bars in fixed or random lengths, with tolerances for length when applicable

  • Tolerances

    • Dimensional tolerances for diameter and length
    • Geometric tolerances including:
      • Straightness, measured as deviation per metre length
      • Roundness to control cross-sectional precision

  • Measurement Methods

    • References to EN 3848 for assessing form deviations like straightness and roundness

  • Standard Implementation

    • Harmonized across member states of CEN, enabling unified quality standards in European aerospace supply chains
    • Mandatory compliance deadlines for national standards organizations

Applications

  • Aerospace Manufacturing
    SIST EN 2044:2004 supports the production of critical aerospace components, where the mechanical integrity and precise dimensions of aluminium round bars affect structural performance and safety.

  • Engineering Design and Fabrication
    Designers rely on the tolerances and dimensions specified to ensure proper fit, function, and interchangeability of parts manufactured from aluminium bars.

  • Supply Chain Quality Control
    Aluminium bar suppliers use this standard to guarantee product quality, supporting aerospace manufacturers' stringent demands.

  • Component Machining and Processing
    Strict roundness and straightness tolerances enable effective machining and subsequent processing in aerospace part fabrication.
