Aluminium and aluminium alloys - Extruded rod/bar, tube and profiles - Part 8: Porthole tubes, tolerances on dimensions and form
Scope: This document 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, see Figure 1) or with a cross section contained within a circumscribing circle (CD) from 10 mm to 350 mm (other than round tube, see Figure 2), supplied in straight lengths.
The temper designations used in this part are according to EN 515.
This document only applies to tube produced by the tube porthole/bridge method.
This document does not apply to:
— extruded tubes produced by the seamless, die/mandrel method (EN 755-7);
— tubes delivered in coils (EN 13957);
— coiled tubes cut to length (EN 13957).

Metallic materials - Sheet and strip - Erichsen cupping test (ISO/DIS 20482:2026)
Scope: ISO 20482:2013 specifies a standard test method for determining the ability of metallic sheets and strips having a thickness from 0,1 mm up to 2 mm and a width of 90 mm or greater to undergo plastic deformation in stretch forming.
For materials that are thicker and when only narrower strips are available, tools of specified dimensions are provided, in which case subscripts are used, as shown in Table 1.
