29、esign which will facilitate consistent production of acceptable castings. The dimensional tolerances of the castings shall be as agreed between the purchaser and manufacturer and indicated on the drawing or the inspection schedule. 4 Pre-production castings 4.1 General 4.1.1 The following requiremen
30、ts shall be specified on the order, drawing and/or inspection schedule in addition to those specified inEN2103-1: number of castings to be examined who shall perform the examination heat treatment condition type and frequency of inspection and testing necessary to evaluate and qualify the manufactur
31、ing process (dimensions, mechanical and metallurgical properties, etc.). 4.1.2 The inspection and testing of pre-production castings shall be carried out and recorded to allow the definition of the optimum techniques to be used for production castings. 4.1.3 The inspection and tests carried out on p
32、re-production castings shall include those which will be carried out on production castings. 4.2 Inspection report In addition to the information required by EN2078, the inspection and test report on the pre-production castings shall provide all technical information to allow evaluation of the quali
33、ty of these parts, e.g.,radiographs, results of dimensional measurements, etc. 4.3 Acceptance of pre-production castings When all inspection and test results relative to pre-production castings have been reported and accepted as satisfactory, the purchaser shall give his written agreement for series
34、 production. The inspection schedule and if required, the manufacturing schedule shall be formally agreed between the manufacturer and purchaser. 1) Published as AECMA pre-standard at the date of publication of this standard. 2) In preparation at the date of publication of this standard. 3) Publishe
35、d as AECMA standard at the date of publication of this standard.EN 2103-3:1991 4 BSI 12-1999 5 Manufacture of production castings 5.1 At the start of production (particularly at the start of series production), the manufacturing schedule may be completed to allow the manufacturer to guarantee the re
36、producibility of the product with more certainty. All information, no matter how minor, shall be recorded in the manufacturing schedule. 5.2 When a manufacturing schedule has been agreed, no change in the manufacturing method shall be made without the written approval of the purchaser. When such cha
37、nges are necessary in the case of, for example: a) alterations of pattern, mould material or position of runners and risers, b) alterations of the casting process, c) alterations of the heat treatment process, the purchaser shall decide if new pre-production castings shall be manufactured and tested
38、. The manufacturing schedule and the inspection schedule shall be modified accordingly. 5.3 Any change of the casting requiring a revised drawing may require at the purchasers or manufacturers request: the manufacture of new pre-production castings, or modification of the manufacturing schedule and/
39、or the inspection schedule. 5.4 Manufacturing schedules and inspection schedules, which are modified during production shall be subjected to the same approval process as the original documents. 5.5 Manufacture Castings shall be poured from a melt, consisting of: 1) remelting stock complying with the
40、 requirements ofEN2103-2 plus, if necessary, pure metals and added elements, or 2) remelting stock complying with the requirements ofEN2103-2 plus a defined and constant percentage of approved scrap, pure metals and added elements, or 3) remelting stock, approved scrap, pure metals and added element
41、s. Their proportion per melt is at the option of the manufacturer. Unless otherwise specified on the order or manufacturing schedule, the following manufacturing method shall be used: for castings in steel: method2) for castings in nickel or cobalt base alloys:method1). 5.6 Correction of distortion
42、shall be carried out only by agreement between the manufacturer and the purchaser. The manufacturer shall be responsible for specifying the conditions under which such correction is to be carried out, subject to any provisions made by the purchaser. The method agreed shall be incorporated in the man
43、ufacturing schedule. If after correction of distortion a further heat treatment is required, the castings shall be re-tested in accordance with the requirements of the material standard. Finally, the castings shall be resubmitted to penetrant or magnetic flaw detection (seeclause6.3). 6 Inspection a
44、nd testing of production castings Inspection and testing shall be carried out on production castings under the same conditions as applied to pre-production castings. 6.1 Dimensions and tolerances The dimensions specially indicated by the purchaser shall be checked on every casting. For other dimensi
45、ons the frequency of examination adopted by the manufacturer shall be sufficient to permit him to certify compliance with the requirements. 6.2 Chemical composition In addition to EN2103-1, the manufacturer shall perform sufficient analyses throughout a prolonged casting cycle to ensure that the com
46、position of all the castings will conform to the requirements of the material standard. For small multiple melts produced in accordance with method1) and2) (see5.5) the frequency of analysis may be reduced by agreement with the purchaser and stated in the inspection schedule. 6.3 External defects 6.
47、3.1 Castings shall be suitably fettled, dressed, cleaned and if appropriate, etched and passivated, to enable inspection to be carried out in a satisfactory manner. 6.3.2 Each casting shall be examined for surface defects by visual inspection and penetrant flaw detection in accordance withEN2002-16
48、or magnetic particle examination in accordance withEN2857 after all specified heat treatment and pressure tests are completed. Castings shall be free from cracks and cracklike indications. If appropriate, the acceptance level for other indications of possible defect shall be detailed on the inspecti
49、on schedule.EN 2103-3:1991 BSI 12-1999 5 6.3.3 Surface defects may be removed by local dressing provided the castings are subsequently within the dimensional tolerances. Dressing shall be followed by flaw detection in accordance with EN2002-16. 6.4 Internal defects Castings shall be radiographically examined in accordance with EN2002-21. Unless otherwise specified on the drawing or inspection schedule, the technique and frequency to be used, shall be as in
