This document has 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 201
25、4/68/EU, see informative Annex ZA, which is an integral part of this document. Within its programme of work, Technical Committee CEN/TC 190 requested CEN/TC 190/WG 7 “Spheroidal graphite, silicon molybdenum and austempered ductile iron” to revise EN 1563:2011. Annex I provides details of significant

BS EN 1563:2018EN 1563:2018 (E) 5 Introduction The properties of spheroidal graphite cast irons depend on their structure. Spheroidal graphite cast irons covered by this European Stan
29、dard are divided in two groups: 1) ferritic to pearlitic spheroidal graphite cast irons; 2) solid-solution strengthened ferritic spheroidal graphite cast irons. The two groups present specific properties, for example: the ferritic grades of the first group present the highest impact energy; the pear
30、lite 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 higher elongation after fracture than that of the ferritic to pearlitic grades; a significant property o
31、f 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 prepared from: separately cast samples; side-by-side cast samples; cast-on samples; samples
32、 cut from a casting. The material grade is defined by mechanical properties measured on machined test pieces prepared from cast samples. If hardness is a requirement of the purchaser as being important for the application, then Annex C provides means for its determination. It is well known that tens
33、ile properties and hardness of spheroidal graphite cast irons are interrelated. When considered by the purchaser as being important for the application, both tensile and hardness properties may be specified. Further technical data on spheroidal graphite cast irons is given in Annexes A, E and H. In
34、this European Standard, a designation system by number, as established in EN 1560 1, is given. NOTE This designation system by number is based on the structure and rules of EN 100272 2 and so corresponds with the European numbering system for steels and other materials. Some spheroidal graphite cast
35、 iron grades can be used for pressure equipment. The permitted material grades of spheroidal graphite cast irons for pressure applications and the conditions for their use are given in specific product or application standards. For the design of pressure equipment, specific design rules apply. Annex
36、 ZA gives information relating to the conformance of the spheroidal graphite cast iron grades to the Pressure Equipment Directive 2014/68/EU. BS EN 1563:2018EN 1563:2018 (E) 6 1 Scope This European Standard defines the grades and the corresponding requirements for spheroidal graphite cast irons. Thi
37、s European Standard specifies 2 groups of spheroidal graphite cast iron grades by a classification based on mechanical properties measured on machined test pieces prepared from cast samples. The first group deals mainly with ferritic to pearlitic grades. The second group deals with solid-solution st
38、rengthened 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 Standard does not cover: ausferritic spheroidal graphite cast irons which are specified in EN 1564 5; low alloyed ferritic spheroidal gra
39、phite cast irons which are specified in EN 16124 6; continuous cast iron bars which are specified in EN 16482 7; austenitic cast irons which are specified in EN 13835 8; spheroidal graphite cast irons used for pipes, fittings and their joints which are the subject of EN 545 9, EN 598 10 and EN 969 1
40、1; the grades of spheroidal graphite cast irons 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 the subject of the applicable European product standards. 2 Normative references The
