ÖNORM EN 754-8

This part of EN 754 specifies the tolerances on dimensions and form for aluminium and aluminium alloy cold drawn porthole tubes with an outside diameter (00)fro m 3 mm to 350 mm (round tube, see figure 1) or with a Cross section contained within a circumscribing circle (CD) from 8 mm to 300 mm (other than round tube, See figure 2), supplied in straight lengths. This standard only applies to tube produced by the portholelbridge method of extrusion only (and then cold drawn to the final dimensions required). This standard only applies to cold drawn tube for general engineering applications made in the following alloys : EN AW-I OSOA, EN AW-1200, EN AW-1350 ; EN AW-3003, EN AW-3103 ; EN AW-5005, EN AW-5005A, EN AW-505lA, EN AW-5251, EN AW-5052 ; EN AW-GIOIA, EN AW-6101 B, EN AW-6005, EN AW-6005A, EN AW-6012, EN AW-6018 ; EN AW-6351, EN AW-6060, EN AW-6061, EN AW-6261, EN AW-6262 ; EN AW-6063, EN AW-6063A, EN AW-6463, EN AW-6081, EN AW-6082 ; EN AW-7003, EN AW-7005, EN AW-7020. This standard does not apply to extruded cold drawn tube produced by the dielmandrel method or coiled tubes.
