33、uct 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 requirements in tables 1 and 2 shall apply in conjunction with those of the relevant material standard. Table 1 relate
34、s 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 tabl
35、es 1 and 2, the requirement is stated in the material standard and/or order. 6.1 Qualification requirements Qualification requirements when invoked by the material standard and/or order are detailed in tables 1 and 2. Unless otherwise agreed between the manufacturer and purchaser the qualification p
36、hase shall be as shown below: 6.2 Release requirements 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 prod
37、uct. 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
38、 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 section 6.2.4 “Capability clause“. 6.2.1 Retests If the test procedure or test piece preparation is fau
39、lty, testing shall be re-applied at the original frequency after rectification of the original cause of failure. 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, one of which shall
40、 be that on which the original results were obtained unless already withdrawn by the manufacturer after suitable identification of the cause of failure.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 one or more tests are unsatisfactory, the batch shall be: - rejected, or -
41、1 O0 % retested and the conforming product accepted, or - partially or fully re-heat treated if heat treatment can rectify 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. COPYRIGHT Asso

43、s 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 and shall be mutually agreed by the manufacturer and the purchaser. 6.2.4 “Capability clause“ Where capability
44、clause is invoked and where sufficient statistical evidence exists, the test shall not be carried out. (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 do
45、es not comply with the requirements, the batch shall be rejected. If sufficient statistical evidence does not exist, the test shall be carried out at a frequency agreed between the manufacturer and purchaser. 6.2.5 Statistical process control Reduction in the extent of release testing, other than th
46、at defined in 6.2.4 above may be negotiated with the purchaser on the basis of appropriate statistical process control and/or statistical 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 followin
47、g: - manufacturers name and address; - order number; - material standard number; - delivery condition and metallurgical code of the product; - quantity and dimensions; - cast and batch number; - batch and/or test samples heat treatment, if required by the purchaser; - results of tests and chemical a
