BS EN 755-8:2008 Aluminium and aluminium alloys. Extruded rod/bar, tube and profiles. Porthole tubes, tolerances on dimensions and form

BS EN 755-8 is the European Standard document and part of the BS EN 755 series, that specifies the tolerances on dimensions and form for aluminium and aluminium alloy extruded porthole tubes with an outside diameter (OD) from 8 mm to 450 mm (round tube) or with a cross section contained within a circumscribing circle (CD) from 10 mm to 350 mm (other than round tube) supplied in straight lengths.

This standard only applies to extruded porthole tube for general engineering applications made in the following alloys:

  • EN AW-1050A, EN AW-1200, EN AW-1350
  • EN AW-3003, EN AW-3103
  • EN AW-5005, EN AW-5005A, EN AW-5049, EN AW-5051A, EN AW-5251, EN AW-5052
  • EN AW-6101A, EN AW-6101B, EN AW-6005, EN AW-6005A, EN AW-6008, EN AW-6110A, EN AW-6012, EN AW-6014, EN AW-6018, EN AW-6351, EN AW-6060, EN AW-6360, EN AW-6061, EN AW-6261, EN AW-6262, EN AW-6262A, EN AW-6063, EN AW-6063A, EN AW-6463, EN AW-6065, EN AW-6081, EN AW-6082; EN AW-6182
  • EN AW-7003, EN AW-7005, EN AW-7108, EN AW-7108A, EN AW-7020.

The temper designations used in this part are according to BS EN 515.

This standard only applies to tube produced by the tube porthole/bridge method.

This standard does not apply to:

  • Extruded tubes produced by the seamless, die/mandrel method (EN 755-7)
  • Tubes delivered in coils (prEN 13957)
  • Coiled tubes cut to length (prEN 13957).

Contents of BS EN 755-8 include:

  • Foreword
  • Scope
  • Tolerances on dimensions
  • Diameter - Round tube
  • Width, depth or width across flats - squares, rectangles, hexagons, octagons
  • Wall thickness variation (eccentricity
  • Length
  • Squareness of cut ends
  • Tolerances on form
  • Straightness
  • Convexity-Concavity
  • Twist
  • Angularity
  • Corner and fillet radii
  • Depth of dents for round tube
  • Wall thickness variation (eccentricity
  • Specifying round tube sizes and tolerances
  • Wall thickness variation for tubes
  • Bibliography
