Information regarding hardness is given in Annex C. 7.3.4 Graphite structure The graphite structure shall be mainly of form V and VI in accordance with EN ISO 945-1.

NOTE 2 Annex D gives more information regarding nodularity. 7.3.5 Matrix structure Information on matrix structure is given in Table E.1 and A.2.2. 8 Sampling 8.1 General Samples shall be made from the same material as that used to produce the casting(s) which they represent. Several types of samples (separately cast samples, cast-on samples, side-by-side cast samples, samples cut from a casting) can be used, depending on the mass and wall thickness of the casting. When relevant the type of sample should be agreed between the manufacturer and the purchaser. Unless otherwise agreed the choice of the option is left to the discretion of the manufacturer. When the mass of the casting exceeds 2 000 kg and its relevant wall thickness 60 mm, cast-on samples or side-by-side samples should preferably be used; the dimensions and the location of the sample shall be agreed between the manufacturer and the purchaser by the time of acceptance of the order. If the spheroidizing treatment is carried out in the mould (in-mould process), the separately cast sample should be avoided. All samples shall be adequately marked to guarantee full traceability to the castings which they represent. The samples shall be subject to the same heat treatment, as that of the castings they represent, if any. Tensile and impact test pieces shall be finally machined from the samples after the heat treatment. SIST EN 1563:2012

8.2.2 Frequency and number of tests Samples representative of the material shall be produced at a frequency in accordance with the process quality assurance procedures adopted by the manufacturer or as agreed with the purchaser. In the absence of a process quality assurance procedure or any other agreement between the manufacturer and the purchaser, a minimum of one cast sample for the tensile test shall be produced to confirm the material grade, at a frequency to be agreed between the manufacturer and the purchaser. When impact tests are required, samples shall be produced at a frequency to be agreed between the manufacturer and the purchaser. 8.2.3 Separately cast samples The samples shall be cast separately in sand moulds and under representative manufacturing conditions. The moulds used to cast the separately cast samples shall have comparable thermal behaviour to the moulding material used to cast the castings. The samples shall meet the requirements of either Figures 1, 2 or 3. The samples shall be removed from the mould at a temperature similar to that of the castings. 8.2.4 Side-by-side cast samples Side-by-side cast samples are representative of the castings concurrently cast and also of all other castings of a similar relevant wall thickness from the same test unit.

Alternative hardness tests may also be agreed upon. The test shall be carried out on the test pieces or at one or several points on the castings after preparation of the testing area in accordance with the agreement between the manufacturer and the purchaser. If the measuring locations are not the subject of an agreement, they shall be chosen by the manufacturer. If it is not possible to carry out the hardness test on the casting, then by agreement between the manufacturer and the purchaser, the hardness test may be carried out on a knob cast-on to the casting. 9.4 Graphite structure examination The graphite structure shall be confirmed by metallographic examination. Non-destructive methods can also give information. In case of dispute, the results of the microscopic examination shall prevail. 10 Retests 10.1 Need for retests Retests shall be carried out if a test is not valid. Retests are permitted to be carried out if a test result does not meet the mechanical property requirements for the specified grade. SIST EN 1563:2012

If the manufacturer conducts retests, two retests shall be carried out for each failed test. If both retests give results that meet the specified requirements, the material shall be deemed to conform to this European Standard. If one or both retests give results that fail to meet the specified requirements, the material shall be deemed not to conform to this European Standard. 10.4 Heat treatment of samples and castings Unless otherwise specified, in the case of castings in the as-cast condition with mechanical properties not in conformance with this European Standard, a heat treatment may be carried out. In the case of castings which have undergone a heat treatment and for which the test results are not valid or not satisfactory, the manufacturer shall be permitted to re-heat treat the castings and the representative samples. In this event, the samples shall receive the same number of heat treatments as the castings. If the results of the tests carried out on the test pieces machined from the re-heat treated samples are satisfactory, then the re-heat treated castings shall be regarded as conforming to the specified requirements of this European Standard. The number of re-heat treatment cycles shall not exceed two. 11 Inspection documentation When requested by the purchaser and agreed with the manufacturer, the manufacturer shall issue for the products the appropriate inspection documentation according to EN 10204:2004. When ordering material for pressure equipment applications, the equipment manufacturer has the obligation to request appropriate inspection documentation according to the applicable product or application standard(s), EN 764-5:2002 and EN 10204:2004. The material manufacturer is responsible for affirming conformity with the specification for the material ordered. SIST EN 1563:2012

Additional information on solid solution strengthened ferritic spheroidal graphite cast irons A.1 General This informative annex applies to solid solution strengthened ferritic spheroidal graphite cast iron grades as specified in Table 3. A.2 Material constitution A.2.1 Chemical composition In order to fulfil the requirements for the mechanical properties, a ferritic structure solid solution strengthened by silicon is recommended. Table A.1 — Guidance values for chemical composition
Designation Si % approx. a P % max. Mn % max. b Symbol Number EN-GJS-450-18 5.3108 3,20 0,05 0,50 EN-GJS-500-14 5.3109 3,80 0,05 0,50 EN-GJS-600-10 5.3110 4,30 0,05 0,50 a Si content may be lower due to other alloying elements. b With lower Mn content (e.g. 0,30 %), machinability and elongation will be improved. With increasing silicon content, the carbon content should be decreased correspondingly. A.2.2 Matrix structure The matrix should be predominantly ferrite with a maximum pearlite content of 5 %. The amount of free cementite should not exceed 1 %. A.2.3 Graphite structure The graphite structure should be mainly of form V and VI in accordance with EN ISO 945-1. Due to the increased silicon content, these solid solution strengthened ferritic spheroidal graphite cast irons may show some compacted graphite (form III) in heavy sections. However ferritic matrices are, also for higher levels of solution strengthening by silicon, much less sensitive to reduced nodularity than cast irons strengthened by substantial amounts of pearlite. A level of approximately 20 % of form lll can be accepted, provided the remainder is mainly of form V and VI, to fulfil the minimum tensile properties specified in this European Standard.
