25、 clearly indicate: quantities to be supplied; dates of delivery; material standard number; delivery condition and metallurgical code of products; dimensions and tolerances or reference to an appropriate dimensional standard; product designation, when required; forwarding address; nature and type of
26、packing, if required; definition and frequency of any special tests and their retest procedures, if required. 5 Health and safety The product in the delivery condition shall fulfil the current health and safety laws of the area of the country when and where it is to be delivered. A product safety da
27、ta sheet shall be available. 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 specification. A manufacturing schedule shall be established and applied in accordance wit
28、h EN 2078. 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. Not with standing previous acceptance complying with this material standard, any product that is found, at a
29、 later stage, to contain such defects 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 onwar
30、ds 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
31、 of the order and/or material standard shall over-ride the requirements of the technical specification. prEN 4800-001:2009 (E) 6 6.2 Qualification requirements Qualification requirements when invoked by the material standard and/or order are detailed in Tables 1 and 2. Unless otherwise agreed betwee
32、n the manufacturer and purchaser the qualification phase shall be run on the first 3 batches coming from 3 ingots. 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 t
33、ests 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 d
34、etail 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 als
35、o in 6.3.5. 6.3.2 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 faulty testing, or test piece preparation, further test samples shall
36、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 identification of the cause of failure. If all retest results are satisfactory, the batch shall be accepted
37、. If one or more tests are unsatisfactory, the batch shall be: rejected, or 100 % retested and the conforming products 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, for whic
38、h redetermination of hydrogen content is required. No product or test sample shall be re-heat treated more than twice 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 suc
39、h 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 purchaser. 6.3.5 Capability clause Where this is invoked and where sufficient evidence exists, the test shall not
40、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 does not comply with the requirements, the batch shall be rejected. prEN 4800-001:2009 (E)
41、 7 If sufficient statistical evidence does not exist, the test shall be carried out at a frequency agreed between the manufacturer and the 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 purch
42、aser 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: manufacturers name and address and, if appropriate, ide
43、ntification of the plant; order number; material standard number; method of melting; delivery condition and metallurgical code of the product; quantity and dimensions; manufacturing and inspection schedule reference; cast and batch number; batch and/or test samples heat treatment condition; results
44、of the tests and retests 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. prEN 4800-001:2009 (E) 8 Table 1 Technical requirements for lines 1 to 29, where appropriate Frequency of te
45、sting Material standard line reference No. Title Requirements Qualification Release 1 Material designation See EN 2032-1. 2 Chemical composition The test samples used for chemical analysis shall be representative of the product and shall be taken from location corresponding to top and bottom of each
46、 ingot produced after the final melting stage. The method of chemical analysis shall be at the discretion of the manufacturer unless otherwise stated in the material standard or order. In cases of dispute, the method of chemical analysis shall be agreed between the manufacturer and purchaser prefera
47、bly using existing chemical analysis. 2 per cast 2 per cast Specific requirements for hydrogen content: The hydrogen content shall be determined on each batch in the delivery condition in accordance with EN 3976. 1 per batch 1 per batch 3 Method of melting Method of melting consists of multiple melt
48、 using combination of non-consumable electrode, consumable electrode and cold hearth (electron beam or plasma arc) melting practices. Some of the following requirements are dependent on the actual melting route non-consumable electrode melting should be used for consolidation purpose only. 1 Raw mat
49、erial: Raw materials shall be purchased only from suppliers approved by the manufacturer and registered in his list of approved suppliers. Approval of suppliers shall be made in accordance with written procedures contained within the quality assurance system of the manufacturer. Titanium sponge and alloying elements: The requirements shall be specified by the manufacturer who shall also esta
