16、 Committee CEN/TC 190 “Foundry technology”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2012, and conflicting national standards shall be withdraw

17、n at the latest by June 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1563:1997. This document has

18、 been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive 97/23/EC, see informative Annex ZA, which is an integral part of this document. Within its progra

19、mme of work, Technical Committee CEN/TC 190 requested CEN/TC 190/WG 7 “Spheroidal graphite, silicon molybdenum and austempered ductile iron” to revise EN 1563:1997. Annex J provides details of significant technical changes between this European Standard and the previous edition. According to the CEN

20、/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lit

BS EN 1563:2011EN 1563:2011 (E) 4 Introduction The properties of spheroidal graphite cast irons depend on their structure. Spheroidal graphite cast irons

22、covered by this European Standard are divided in two groups: 1) ferritic to pearlitic spheroidal graphite cast irons which were in the previous standard; 2) solid-solution strengthened ferritic spheroidal graphite cast irons which were not in the previous standard. The two groups present specific pr

23、operties, for example: the ferritic grades of the first group present the highest impact energy; the pearlite containing grades are more suitable for wear resistance applications; the solid-solution strengthened ferritic grades present for an equivalent tensile strength a higher proof strength and a

24、 higher elongation than that of the ferritic to pearlitic grades; a significant property of these solid-solution strengthened ferritic grades is the reduced hardness variation resulting in an improved machinability. The mechanical properties of the material can be evaluated on machined test pieces p

25、repared from: separately cast samples; side-by-side cast samples; cast-on samples; samples cut from a casting. The material grade is defined by mechanical properties measured on machined test pieces prepared from cast samples. If hardness or un-notched impact energy are a requirement of the purchase

26、r as being important for the application, then Annex C or Annex I provide means for its determination. It is well known that tensile properties and hardness of spheroidal graphite cast irons are interrelated. When considered by the purchaser as being important for the application, both tensile and h

27、ardness properties may be specified. Further technical data on spheroidal graphite cast irons is given in Annexes A, E and F. In this European Standard a new designation system by number, as established in EN 1560:2011 1, is given. NOTE This designation system by number is based on the structure and

28、 rules of EN 10027-2 2 and so corresponds with the European numbering system for steel and other materials. Some spheroidal graphite cast iron grades can be used for pressure equipment. The permitted material grades of spheroidal graphite cast iron for pressure applications and the conditions for th

29、eir use are given in specific product or application standards. For the design of pressure equipment, specific design rules apply. Annex ZA gives information relating to the conformance of permitted spheroidal graphite cast iron grades to the Pressure Equipment Directive 97/23/EC. BS EN 1563:2011EN

30、1563:2011 (E) 5 1 Scope This European Standard defines the grades and the corresponding requirements for spheroidal graphite cast irons. This European Standard specifies 2 groups of spheroidal graphite cast iron grades by a classification based on mechanical properties measured on machined test piec

31、es prepared from cast samples. The first group deals with ferritic to pearlitic grades. The second group deals with solid-solution strengthened ferritic grades. This European Standard does not cover technical delivery conditions for iron castings (see EN 1559-1 3 and EN 1559-3 4). This European Stan

32、dard does not cover all aspects of: ausferritic spheroidal graphite cast irons which are specified in EN 1564 5; low alloyed ferritic spheroidal graphite cast irons which are specified in EN 16124 6; austenitic cast irons which are specified in EN 13835 7; spheroidal graphite cast irons used for pip

33、es, fittings and their joints which are the subject of EN 545 8, EN 598 9 and EN 969 10; the grades of spheroidal graphite cast iron as specified in EN 545 which are used for products such as industrial valves, non industrial manually operated shut-off valves and flanges and their joints, which are

34、the subject of the applicable European product standards. 2 Normative references The following referenced documents are indispensable for the application of this document.
