This European Standard shall be given the status of a national standard, either by public
16、ation of an identical text or by endorsement, at the latest by May 1999, and conflicting national standards shall be withdrawn at the latest by May 1999. This European Standard is one of several which specify technical delivery conditions for castings. The other standards in this series are: EN 1559

20、ntroduction CENiTC 209 “Zinc and zinc alloys“ has prepared a product standard covering zinc alloy castings. In order to assist manufacturers and purchasers to prepare proper contractual arrangements and prevent misunderstanding, CEN/TC 190 “Foundry technology“ approved the preparation of a series of
21、 standards covering technical delivery conditions. These have been prepared as separate parts. This European Standard covers the additional technical delivery conditions for zinc alloy castings, e.g. optional information, manufacturing process, welding operation, additional requirements regarding co
22、ndition of the casting, test methods. This European Standard cannot be used alone for compiling a specification for ordering and supplying zinc alloy castings, but as a complement to EN 1559-1. The following symbols are used in this standard: - clauses and subclauses preceded by indicates no additio
23、nal requirements to EN 1559-1; - subclauses preceded by * indicates requirements that are optional, which can be agreed at the time of ordering; - clauses and subclauses without a symbol are mandatory. 1 Scope This pari of EN 1559 applies to castings made from zinc alloys produced by sand casting, p
24、ermanent mould casting, pressure die casting, centrifugal casting, continuous casting or investment casting. This standard specifies the additional technical delivery conditions for zinc alloy castings. This standard does not apply to ingots, bars, billets (or other shapes) for further reprocessing,
25、 such as remelting, grinding or extrusion. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated ref
26、erences, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references, the latest edition of the publication referred to applies. EN 1371-1 Founding - Liquid penetrant inspection - Par

32、cordance with prEN 12681. 7.3.3.2 The surface condition of the casting shall be agreed either at the time of ordering or shall correspond to the initial sample. Page 5 EN 1559-6 : 1998 7.3.3.3 For pressure die castings, unacceptable external and internal discontinuities shall lead to a rejection of
33、the part. 7.3.3.4 7.3.4 Condition of the casting 7.3.5 Mass of the casting 7.3.6 - Additional requirements regarding the condition of the casting In order to eliminate leaks in castings it is possible with the approval of the purchaser to use impregnation procedures. The impregnation medium and meth
34、od, maximum permitted size of discontinuities and retest procedures shall be agreed between the manufacturer and the purchaser. If applicable, density evaluation by weight measurements in air and water to agreed criteria shall be used to estimate the soundness of the casting. 8 Testing and documents
