DIN EN 10217-7:2015-01 EN 10217-7:2014 (E) 41 Scope This Part of EN 10217 specifies the technical delivery conditions in two test categories for welded tubes of circular cross-section made of austenitic and austenitic-ferritic stainless steel which are intended for pressure
31、and corrosion resisting purposes at room temperature, at low temperatures or at elevated temperatures. NOTE Once this standard is published in the Official Journal of the European Union (OJEU) under Directive 97/23/EC, pressure equipment directive, presumption of conformity to the Essential Safety R
32、equirements (ESR) of Directive 97/23/EC is limited to technical data of materials in this standard and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of thi
33、s specific item of equipment to verify that the ESRs of the Pressure Equipment Directive are satisfied, needs to be done by the designer or manufacturer of the pressure equipment, taking also into account the subsequent manufacturing processes which may affect properties of the base materials. 2 Nor
