In order to assist manufacturers and purchasers to prepare proper contractual arrangements and prevent misunderstanding, CEN/TC
21、 190 approved 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, addition
22、al requirements 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
23、of the same clauses of EN 1559-1 have to be met. BS EN 1559-5:2017EN 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 a
24、lloy 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 referenc
25、es The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.

32、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/o
33、r 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.

Moreover, for the same area of the casting different acceptance criteria can be specified according to the non-destructive test methods s
40、elected. 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 discontinuitie
41、s, when these discontinuities are totally removed by machining.

45、iteria. NOTE 1 Assessment is usually carried out with an agreed magnification and can include the nature, shape and distribution of the structural constituents. NOTE 2 A cooling curve/thermal analysis carried out on a sample of liquid alloy before casting can help to predict the metallurgical struct
46、ure 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 st
