BS EN 941:2014EN 941:2014 (E) 4 1 Scope This European Standard specifies the particular requirements for wrought aluminium and aluminium alloys in the form of circle or circle stock for general applications. It app
17、lies to: Circles made out of hot or cold rolled circles stock by: Blanking: thickness 0,2 mm up to including 12 mm and with a diameter up to 1 000 mm; Sawing or shearing: thickness 0,2 mm up to and including 200 mm with a diameter up to 3 500 mm; Hot or cold rolled circle stock with a thickness from
18、 0,2 mm up to and including 200 mm and with a width up to 3 500 mm. It does not apply to slugs for impact extrusions or to circle and circle stock for culinary utensils applications which are dealt with in other European Standards. 2 Normative references The following documents, in whole or in part,
