33、rom the first 3 batches 6 Technical requirements Intermediate Samples from the 4th and 5th batches The product shall satisfy the requirements of the material standard and/or order. Instructions for the use of the material standard are contained in EN 4258. Unless otherwise specified, the requirement
34、s in tables 1 and 2 shall apply in conjunction with those of the relevant material standard. Table I 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 ma
35、terial standard details specific qualification requirements. If a specific line number is not shown in tables I and 2, the requirement is stated in the material standard and/or order. 6.1 Qualification requirements 6.2 Release requirements Release testing shall be the responsibility of the manufactu
36、rer. The purchaser reserves the right to perform any of the inspections andlor 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 r
37、elease 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 andlor test for release shall be carried out if corresponding acceptance cr
38、iteria andlor values are stated in the applicable material standard, but see also section 6.2.4 “Capability clause“. 6.2.1 Retests 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. Wh
39、en 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frequency from the product, one of which shall be that on which the original results were obtained unless already withdrawn by the manufacturer after suitable id
40、entification of the cause of failure. If all retest results are satisfactory, the batch shall be accepted. If one or more tests are unsatisfactory, the batch shall be: - rejected, or - 100 % retested and the conforming lengths accepted, or - partially or fully re-heat treated if heat treatment can r
41、ectify the cause of the failure and tested as a completely new batch except for chemical composition. No product or test sample shall be re-heat treated more than twice.

42、: 2001 6.2.2 Rejection Any failure to meet the requirements of the material standard shall be cause for rejection. 6.2.3 Special tests Special tests additional to those detailed in the material standard may be required by the purchaser. In such cases, the nature of the test, method, frequency and ac
43、ceptance criteria shall be specified on the order or inspection schedule and shall be mutually agreed by the manufacturer and the purchaser. 6.2.4 Capability clause Where this is invoked and where sufficient evidence exists, the test shall not normally be carried out unless specifically requested by
44、 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 sufficient statistical evidence does not exist, the test shall be ca
45、rried out at a frequency agreed between the manufacturer and purchaser. e 6.2.5 Statistical process control Reduction in the extent of release testing, other than that defined in 6.2.4 above may be negotiated with the purchaser on the basis of appropriate statistical process control andlor statistic
46、al data. 6.2.6 Inspection and test report The manufacturer shall furnish, with each delivery, a report conforming to the requirements of EN 2078 stating the following: - manufacturers name and address; - order number; - material standard number; - delivery condition and metallurgical code of the pro
47、duct; - quantity and dimensions; - cast and batch number; - batch and/or test samples heat treatment, if required by the purchaser; - results of the tests and chemical analysis.
