(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 pre-production castings shall include those which will be carried out on production castings 4.2 Inspection report In addition to the information required by EN 2078, the inspection and test report on the pre-production castings shall provide all technical information to allow evaluation of the quality 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 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 preparation at the date of publication of this standard 3) Published as AECMA

production), the manufacturing schedule may be completed to allow the manufacturer to guarantee the reproducibility 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 changes 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 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 purchaser’s or manufacturer’s request: — the manufacture of new pre-production castings, or — modification of the manufacturing schedule and/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 requirements of EN 2103-2 plus, if necessary, pure metals and added elements, or 2)
