EN 4400-6:2019 (E) 7 6 Technical requirements 6.1 General The product shall be manufactured in accordance with the requirements of the relevant material standard and the applicable requirements of this technical specification. A manufacturing schedule shall be established and applied in accordance with EN 2078. The product shall satisfy the requirements of the material standard and/or order and shall be free from irregularities prejudicial to the subsequent manufacture or use of this product. Notwithstanding previous acceptance complying with the material standard and this technical specification, any product that is found, at a later stage, to contain such discontinuities shall be rejected. Unless otherwise specified, the requirements in Tables 1 and 2 shall apply in conjunction with those of the relevant material standard. Table 1 relates to lines 1 to 29 (inclusive) of the material standard and Table 2 relates to lines 30 onwards in which the sub-line format is also used. Lines 2 to 98 may also be opened in line 100 if the material standard details specific qualification requirements. If a specific line number is not shown in Tables 1 and 2, the requirement is stated in the material standard and/or order. The requirements of the order and/or material standard shall over-ride the requirements of this technical specification. 6.2 Qualification requirements See line 100 in Table 2 of this technical specification. 6.3 Release requirements 6.3.1 Release tests Release testing shall be the responsibility of the manufacturer. The purchaser reserves the right to perform any of the inspections and/or tests required by the material standard and/or order. The test samples shall be representative of the product. When required, the manufacturer shall inform the purchaser of the planned dates for extraction of samples and release testing in order that these operations may be witnessed. Tables 1 and 2 detail the requirements for each line of the material standard. Unless otherwise specifically requested by the purchaser, a particular inspection and/or test for release shall be carried out if corresponding acceptance criteria and/or values are stated in the applicable material standard, but see also 6.3.5 "Capability clause". 6.3.2 Retests If any requirement is not met and if the test procedure or test piece preparation is faulty, testing shall be re-applied at the original frequency after rectification of the original cause of failure on a test sample located near the original. When failure cannot be attributed to faulty testing or test piece preparation, further test samples shall be selected at twice the original frequency from the product, 1 (one) of which shall be that on which the original results were obtained unless already withdrawn by the manufacturer after suitable identification of the cause of failure. If all retest results are satisfactory, the batch shall be accepted. If 1 (one) or more tests are unsatisfactory, the batch shall be rejected. SIST EN 4400-6:2019

EN 4400-6:2019 (E) 8 6.3.3 Rejection Any failure to meet the requirements of the material standard shall be cause for rejection. 6.3.4 Special tests Special tests may be required by the purchaser. In such cases, the nature of the test, method, frequency and technical requirements shall be specified on the order or inspection schedule or forging drawing and shall be mutually agreed by the manufacturer and the purchaser. 6.3.5 Capability clause Where sufficient statistical evidence exists that the required acceptance criteria can be routinely achieved (usually tensile testing of forging stock) and with the agreement of the purchaser, the "capability clause" may be invoked when and where stated in the material standard and/or this technical specification. In such cases, the test need not be carried out for release purposes unless specifically requested by the purchaser. However, this in no way reduces the obligations of the manufacturer to fulfil the requirements. If subsequent testing indicates that the product does not comply with the requirements, the batch shall be rejected. If the "capability clause" is invoked but sufficient statistical evidence does not exist, the test shall be carried out for release purposes at a frequency agreed between the manufacturer and purchaser. 6.3.6 Statistical process control Reduction in the extent of release testing, other than that defined in 6.3.5 above may be negotiated with the purchaser on the basis of appropriate statistical process control and/or statistical data. 6.3.7 Inspection and test report The manufacturer shall furnish, with each delivery, a report conforming to the requirements of EN 2078 stating the following: a) manufacturer's name and address and, if appropriate, identification of the plant; b) order number; c) the following statement: "This product has been tested according to EN 4400-6"; d) material standard number; e) delivery condition and metallurgical code of the product; f) quantity and dimensions; g) manufacturing and inspection schedule reference, if appropriate; h) cast and batch number; i) batch and/or test sample heat treatment, if required by the purchaser; j) results of all tests and chemical analysis and re-tests, if any. 6.4 Traceability Each product shall be traceable to the cast, production batch and/or heat treatment batch at all stages of manufacture, testing and delivery.

The manufacturer shall define the raw materials, processes and inspection requirements in a manufacturing schedule in accordance with EN 2078 and EN 9133. The manufacturer shall make this available to the purchaser upon request. Changes to any manufacturing schedule agreed during qualification of the pre-production forgings and which may adversely affect the quality of the product shall be advised by the manufacturer and shall be subject to written approval from the purchaser. Each product shall be traceable to the cast/production batch at all stages of manufacture, testing and delivery. − 4.3 Limit dimension(s) Minimum and/or maximum size of the product expressed as the nominal thickness, a or diameter D.
