適用范圍：1.1 This European Standard specifies the technical delivery requirements for seamless and welded butt-weldingfittings (elbows, concentric and eccentric reducers, equal and reducing tees, caps) made of austenitic andaustenitic-ferritic (duplex) stainless steel which are intended for pressure and corrosion resisting purposes at roomtemperature, at low temperature or at elevated temperatures.It specifies:? the type of fittings;? type A (see 7.2)? type B (see 7.3)? the steel grades;? the mechanical properties;? the dimensions and tolerances;? the requirements for inspection and testing;? the inspection documents;? the marking;? the handling and packaging.NOTE In the case of a harmonised supporting standard for materials, presumption of conformity to the EssentialRequirement(s) (ESRs) is limited to technical data of materials in the standard and does not presume adequacy of the materialto a specific item of equipment. Consequently the technical data stated in the material standard should be assessed against thedesign requirements of this specific item of equipment to verify that the ESRs of the Pressure Equipment Directive (PED) aresatisfied.1.2 Unless otherwise specified in this European Standard the general technical delivery requirements inEN 10021 apply.
