For definitions specific to aluminium alloys, see EN 12258 and with the following additions for aluminium alloy plate: 3
31、.1 Batch As defined in EN 4259 with the following additions: - For solution heat treatment using a continuous furnace, a continuous run oft I 8 h may be considered as the same heat treatment charge. - For tensile testing only, the special provision in table 1, line 8.1, “Batch size for testing“ appl
32、ies. 3.2 Controlled stretching Stretching performed after solution heat treatment and quenching for the purpose of reducing internal stresses and/or deviation from flatness. The stretching is defined by a minimum and maximum permanent elongation stated in the material standard. NOTE: In certain case
33、s controlled stretching is critical to the achievement of the specified mechanical properties. 3.3 Machined plate Product manufactured from plate with one or more of its major surfaces machined 3.4 Parent plate Plate undergoing the same operations over its whole length (including solution heat treat
34、ment, controlled stretching, ageing) before being cut. 4 Wording of order The order shall clearly indicate: - quantities to be supplied; - dates of delivery; - material standard number; - delivery condition; - dimensions and tolerances or reference to an appropriate dimensional standard; - forwardin
35、g address; - nature and type of packing, if required; - definition and frequency of any special tests and their retest procedures, if required. 5 Health and safety Plate in the delivery condition shall fulfil the health and safety laws of the area of the country when and where it is to be delivered.
36、 A product safety data sheet shall be available.

37、Page 6 prEN 4400-1 : 1999 Starting 6 Technical requirements Intermediate Plate shall satisfy the requirements of the material standard andlor 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
38、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
39、 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. Sample(s) from the first 3 batches 6.1 Qualification requirements Qualification requirements when invoked by the material standard and/or order are
40、detailed in tables I and 2. Unless otherwise agreed between the manufacturer and purchaser the qualification phase shall be as shown below: Samples from the 4th and 5th batches 6.2 Release requirements Release testing shall be the responsibility of the manufacturer. The purchaser reserves the right
41、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 ope
42、rations 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
43、 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. When failure cannot be attributed to fau
44、lty testing, or test piece preparation, further test samples shall be selected at twice the original frequency from the plate, 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
45、 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 plates accepted, or - partially or fully re-heat treated if heat treatment can rectify the cause of the failure and teste
46、d as a completely new batch except for chemical composition. No plate or test sample shall be re-heat treated more than twice.

In such cases, the natu
48、re of the test, method, frequency and technical requirements shall be specified on Ehe 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 will not normally be ca
49、rried out for release purposes. However, this in no way reduces the obligations of the manufacturer to fulfil the requirements. If subsequent testing indicates that the plate does not comply with the requirements, the batch shall be rejected. 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
