25、e de Normalisation (AFNOR). Within its programme of work, Technical Committee CEN/TC 132 entrusted CEN/TC 132/WG 5, Extruded and drawn products, to work out the following standard: EN 754-5, Aluminium and aluminium alloys Cold drawn rod/bar and tube Part 5: Rectangular bars, tolerances on dimensions
26、 and form. This standard is part of a set of eight standards.

This European Standard shall be given the status of a national standard, either by publication of an identical test or by endorsem
30、ent, at the latest by May 1996, and conflicting national standards shall be withdrawn at the latest by May 1996.
