25、4 Introduction The European Organization for Standardization (CEN) draws attention to the fact that it is claimed that compliance with this document may involve the use of patents applied to seven steel grades. CEN takes no position concerning the evidence, validity and scope of these patent rights.
26、 The holder of these patent rights has ensured CEN that they are willing to negotiate licenses, under reasonable and non-discriminatory terms and conditions, with applicants throughout the world. In this respect, the statements of the holders of these patent rights are registered with CEN. Informati

28、 10088-2:2014 (E) 5 1 Scope This European Standard specifies the technical delivery conditions for hot or cold rolled sheet/plate and strip of standard grades and special grades of corrosion resisting stainless steels for general purposes. NOTE General purposes include the use of stainless steels in
29、 contact with foodstuffs. The general technical delivery conditions specified in EN 10021 apply in addition to the specifications of this European Standard, unless otherwise specified in this European Standard. This European Standard does not apply to components manufactured by further processing of
30、 the product forms listed above with quality characteristics altered as a result of such further processing. 2 Normative references The following referenced documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
