This European Standard is considered tobe a supporting standard to those application and product standards which in themselves supportan essential safety requirement of a New Approach Directive and which make reference to thisEuropean Standard.According to the CEN/CENELEC

17、d and the United Kingdom.Page4EN 10254: 19991 ScopeThis 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
18、 the material to the form of the die.Similar products such as warm extrusions and upset forgings, are also regarded as part of theprocess.This European Standard applies also to closed die forgings when their surface is partially treatedsubsequently by cold forming or coining, in order to improve the
19、 surface quality or to obtain moreprecise dimensional accuracy.This standard does not apply to open die forgings, process in which the tooling does not fullysursound the components produced.2 Normative referencesThis European Standard incorporates by reference provisions from specific editions of ce
