Anotácia textu normy ASTM B210/B210M-26 :

This specification covers aluminum and aluminum-alloy drawn seamless tubes in straight lengths and coils for general purpose. The tube shall be produced by drawing an extruded tube made from hollow extrusion ingot (cast in hollow form or pierced) and extruded by the use of the die and mandrel method. The tubes shall conform to the chemical composition requirements specified. The determination of chemical composition shall be made in accordance with suitable chemical (test methods E 34), or spectrochemical (test methods E 607 and E 1251), methods. The tube shall conform to the tensile property requirements specified. The tension tests shall be made in accordance with test methods B 557M. Flattening test specimens shall be flattened sidewise under a gradually applied load so as to give a uniform radius of bend until the minimum outside diameter under load is not more than F times the wall thickness of the tube as specified. The specimen shall be forced axially with steady pressure over a hardened and polished tapered steel pin having a 74° included angle, to produce a flare having the permanent expanded outside diameter specified. When specified, heat treatment of applicable tempers shall be in accordance with practice B 918. The different methods for leak testing of tubes are presented.
