scope:

This standard specifies the material requirements and testingprocedures applicable to wrought and cast aluminium and aluminiumalloys intended for use in the production of pressure equipment.This European Standard covers: ? the products forms, grades andtempers of wrought and cast aluminium and aluminium alloys whichmay be used for such applications together with data for wroughtand cast alloys over their permissible working temperature ranges;? the permissible alloys/ tempers covered by this are those givenin Table A.1 and in B.1 for wrought alloys and in Table A.2 and inB.2 for castings; ? the technical conditions for inspection anddelivery, mechanical property limits and tolerances on form anddimensions by reference to the appropriate European standards forthe relevant wrought and cast aluminium and aluminium alloys, and ?additional requirements which are specific to pressure equipmentapplications. It applies to hot-rolled plate, cold-rolled sheet/strip/ circles, extruded or extruded and cold drawn rod/bar, tube,extruded open / hollow profiles, forgings and castings, by thisstandard are those given in Table A.1 for wrought alloys and inTable A.2 for castings. It is the sole objective of this standardto cover materials only for pressure purposes and it excludes anyelements of fabrication or fabrication methods for pressureequipment; such information can be found in the relevant standardslisted in the ?Bibliography? section.
