Notes:
1.  Dimensional tolerances have been rounded down to the nearest 0.05mm, because dial callipers used to measure metal dimensions are almost universally graduated at intervals at 0.05mm.

2.  *Metal dimensions refer to solid metal dimensions or any measurement unbroken by a gap or void. For tolerances across gaps or voids refer to the A.D.C. standard.

Footnotes
1 The thickness of the cross-section or wall thickness from which the tension specimen is taken determines the applicable mechanical properties.

2 For material of such dimensions that a standard test specimen cannot be taken, or for material thinner than 1.6mm the test for elongation is not required.

To calculate NOMINAL mass (kg/m) of extruded aluminium sections, tube, etc:
(a) Calculate cross-section area (mm2);
(b) Multiply by 0.00271.

To calculate FACTOR (i. e. the "difficulty of extrusion" factor):
(a) Calculate the perimeter of the section (Note: for hollows, add outside perimeter and inside perimeter);
(b) Divide this by the nominal kg/m of the section.
