21、the manufacture, inspection and testing of steel, nickel base or cobalt base alloy remelting stock and castings. Particular requirements applicable to remelting stock and castings are defined in EN2103-2 and EN2103-3 respectively. Unless otherwise specified on the drawing, order or inspection schedu
22、le, the reference to EN2103 only defines one quality level which is quality level2in Table4or5of EN2103-3. 2 Field of application Unless otherwise specified on the drawing, order or inspection schedule this standard shall be applied when referenced in the relevant EN material standard. By agreement
23、between the purchaser and manufacturer it may also be applied to other materials or delivery conditions not covered by EN standards. The agreements shall be formalized by reference to this standard on the drawing, order or inspection schedule. 3 References EN 2000, Aerospace series Quality assurance

26、mixed in the same furnace or ladle before pouring 4.2 cast solid metal resulting from the pouring of a single melt 4.3 parent cast a cast of remelting stock to be used for the production of castings 4.4 approved scrap scrap used for the production of remelting stock. It arises from the manufacturers
27、 own production or from that of the purchaser. Scrap used for the production of castings shall be restricted to runners and risers, rejected castings and heavy fettling scrap but shall exclude machining chips, turnings or small particles scrap shall be the subject of preparation and evaluation by ap
28、proved procedures and facilities which shall include verification of chemical composition, freedom from contamination and the absence of foreign material 4.5 product in this standard the term product covers remelting stock as well as castings 4.6 remelting stock metal supplied in cast or wrought for

If otherwise agreed or if there is more than one heat treatment condition in the material standard, the condition of supply shall be specified on the order, drawing or manufacturing schedule. 6.5 If a specific heat treatment temperature (value and t
36、olerance) is stated, that temperature shall be mandatory. If a heat treatment temperature range is stated, a temperature within that range, reduced by the furnace tolerances, shall be selected to give the required properties. Unless otherwise specified, the furnace charge shall be maintained at that
37、 temperature subject to the following tolerances inTable 1, for the periods stated. Table 1 7 Traceability Remelting stock and each casting shall be identifiable as to their melt and parent-cast and if appropriate, to its heat treatment batch at all stages of manufacture and delivery. 8 Freedom from
38、 defects The products shall be free from harmful defects and notwithstanding previous acceptance of products complying with this standard, any product that is found, at a later stage, to contain such defects may be rejected. 9 Testing The tests required by the material standard, the order or inspect
39、ion schedule shall be made in accordance with the requirements of the appropriate test standard. If a test standard does not exist, the method to be used shall be agreed between manufacturer and purchaser. Unless otherwise specified on the order, drawing or inspection schedule, the frequency of samp
40、ling shall be as given in EN2103-2 or EN2103-3. The location of test samples shall be as indicated on the drawing or inspection schedule. The test samples and associated test pieces shall be marked in such a manner as to ensure that their identity and location with respect to the product and the bat
41、ch is maintained. 9.1 Chemical composition 9.1.1 The chemical composition of the delivered product shall comply with the requirements of the relevant material standard and the order. Selected temperature C Tolerances C1250 15EN2103-1:1991 BSI 12-1999 5 9.1.2 The chemical composition of each melt or
42、parent-cast shall be determined, except as qualified by EN2103-3, clause6.2. The samples taken for analysis shall be representative of the melt or the parent-cast. The method of analysis shall be selected by the manufacturer but in case of dispute, the method set out in the relevant ISO standard sha
43、ll be used. If no ISO standard exists, a fundamental method of chemical analysis shall be used. 9.1.3 Elements not quoted in the material standard shall not be intentionally added to the alloy without the agreement of the purchaser, except those needed for the purpose of deoxidation, degassing or gr
44、ain refinement of the melt. Precautions shall be taken to prevent inclusions as a result of added elements during manufacture and to avoid contamination of the products. For special applications the purchaser, by agreement with the manufacturer, may set a limit to the amount of one or more such elem
