Introduction
CEN/TC 133 “Copper and copper alloys” was established in 1988 to prepare and maintain standards in
the field of unwrought, wrought and cast products made from copper and copper alloys. Its
responsibilities included developing, defining, specifying and giving guidance on, as appropriate, material
compositions, designations, terminology, dimensions and tolerances, mechanical and physical
characteristics, conditions of delivery and methods of testing peculiar to copper and copper alloys.
During the development of standards for copper and copper alloy products, the experts realized the
necessity and seized the opportunity:
a) to coordinate and in some cases also to rationalize the composition limits which already existed for
the various product forms;
b) to establish unique, new and identifiably European designations for copper and copper alloys,
including a numerical option to be particularly convenient for computerized handling;
c) to confirm, clarify and redefine where necessary, the terminology which already existed in common
usage, at the international level or in customs nomenclature.
CEN/TC 133 decided, in view of the new form of presentation and new parameters for the description
and provision of information on copper and copper alloy products, to prepare and publish the present
consolidation and summary of essential details.
