適用范圍：This European Standard specifies the general delivery conditions for steel closed die forgings. These forgings are produced by blow or pressure of the heated product at a suitable temperature (hot or warm) in a die, which in the forming process shapes the material to the form of the die. Similar products, such as warm extrusions and upset forgings, are also regarded as part of the process. This European Standard applies also to closed die forgings when their surface is partially treated subsequently by cold forming or coining, in order to improve the surface quality or to obtain more precise dimensional accuracy. This standard does not apply to open die forgings, processes in which the tooling does not fully surround the components produced.
