Gießereiwesen - Temperguss This European Standard was approved by CEN on 14 January 2012.
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management Centre has the same status as the official versions.
CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and United Kingdom.

(ISO 6892-1:2009) 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 malleable cast iron cast material, mainly iron and carbon based, which solidifies in the as-cast condition with a graphite-free (white) structure and achieves its final properties after a heat treatment 3.2 whiteheart malleable cast iron cast material, mainly iron and carbon based, which is cast white and then given a heat treatment in a decarburizing atmosphere to produce a material which is partially or entirely decarburized. Any remaining graphite is in the form of temper carbon 3.3 blackheart malleable cast iron cast material, mainly iron and carbon based, which is cast white and then given a non-decarburizing heat treatment, to produce a material in which all graphite is in the form of temper carbon SIST EN 1562:2012

5 Order information The following information shall be supplied by the purchaser: a) the number of this European Standard; b) the designation of the material; c) the relevant wall thickness of the casting; d) any special requirements. All requirements shall be agreed between the manufacturer and the purchaser by the time of acceptance of the order e.g. technical delivery conditions according to EN 1559-1 and EN 1559-3. 6 Manufacture The method of manufacture of malleable cast iron as well as its chemical composition and heat treatment shall be left to the discretion of the manufacturer, who shall ensure compliance with the property requirements given in this European Standard for the material ordered. NOTE To produce structures such as ferrite, pearlite or other transformation products of austenite, both material types (groups) depend upon either the malleablising heat treatment or the subsequent additional heat treatment and/or additions of alloying elements. For castings intended to be given additional treatment (such as galvanizing) and/or in the case of castings for use at low temperatures to optimize the impact energy of the material, the phosphorous content should not exceed 0,10 %. SIST EN 1562:2012

7.5 Impact energy The minimum impact energy values measured on V-notched test pieces machined from cast samples given in Table 3 at room temperature, if applicable, shall only be determined if specified by the purchaser by the time of acceptance of the order. Impact energy testing is normally requested for EN-GJMB-350-10 only. The method of testing shall be in accordance with 9.4. NOTE If the purchaser requires impact testing to be performed on whiteheart malleable cast iron or other grades of blackheart malleable cast irons, then the Charpy un-notched test should be used (see informative Annex B).
