23、 Kingdom. DIN EN 1559-5:2017-05 EN 1559-5:2017 (E) 4 Introduction CEN/TC 190 “Foundry Technology” has prepared material standards covering magnesium alloy castings. In order to assist manufacturers and purchasers to prepare proper contractual arrangements and prevent misunderstanding, CEN/TC 190 app
24、roved the preparation of a series of standards covering technical delivery conditions. These have been prepared as separate parts. This part of EN 1559 covers the additional technical delivery conditions for magnesium alloy castings, e.g. optional information, manufacturing process, additional requi
25、rements regarding the condition of the casting and test methods. This part of EN 1559 cannot be used alone for compiling a specification for ordering and supplying magnesium alloy castings, but as a complement to EN 1559-1. The clauses marked with a single dot indicate that the requirements of the s
26、ame clauses of EN 1559-1 have to be met. DIN EN 1559-5:2017-05 EN 1559-5:2017 (E) 5 1 Scope This part of EN 1559 specifies the additional technical delivery conditions for castings (see EN 1753) and cast anodes (see EN 12438) made from magnesium alloys. This part of EN 1559 applies to magnesium allo
27、y castings produced in sand or permanent moulds or by pressure die casting, centrifugal casting, continuous casting or investment casting. This part of EN 1559 does not apply to ingots, bars, billets (or other shapes) for further reprocessing, such as re-melting or extrusion. 2 Normative references

35、t magnesium alloys by material number or material symbol shall be in accordance with EN 1754. Both designations describe the magnesium alloys according to their chemical composition. The designation shall be used on the drawings and in the order. To identify the temper (heat treatment condition) and
36、/or the casting process, the designation shall be supplemented with symbols preceded and separated from each other by a hyphen (-): for tempers as given in EN 1753; for casting processes as given in EN 1753 and EN 12438.

42、tion, orientation and size of possible discontinuities in the areas to be tested. Different acceptance criteria can be specified for different areas of the same casting. Moreover, for the same area of the casting different acceptance criteria can be specified according to the non-destructive test me
43、thods selected. For all non-destructive testing methods, the acceptance criteria (discontinuity levels) can be graded with increasing number and/or extent of indications. Unless specifically agreed, discontinuities revealed on cast surfaces which are to be machined, are not to be regarded as discont
44、inuities, when these discontinuities are totally removed by machining.

The
46、impregnation medium and method, maximum permitted size of discontinuities and retest procedures shall be agreed between the manufacturer and the purchaser. 7.3.6.2 Where appropriate, a macroscopic examination of a suitably prepared section shall be carried out to assess the grain structure and/or st
47、ructural inadequacy of a casting to agreed criteria. NOTE Assessment is usually carried out with naked eyes or with an agreed magnification. 7.3.6.3 Where appropriate, a microscopic examination of a suitably prepared section shall be carried out to determine the metallurgical structure of a casting

NOTE 2 A cooling curve/thermal analysis carried out on a sample of liquid alloy before casting can help to predict the metallur
49、gical structure of the casting. 7.3.6.4 If applicable, density evaluation by weighting in air and water to agreed criteria shall be used to estimate the soundness of the casting. 8 Inspection 8.1 General 8.2 Type of inspection documents and type of inspection The requirements given in the applicable material standard shall also apply. 8.3 Test unit 8.3.1 Formation of test units 8
