18、 Spain, Sweden, Switzerland and the United Kingdom. Page 4 EN 1559-6:1998 Introduction CEWC 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,
19、CEN/TC 190 Foundry technology approved the preparation of a series of 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, manufactu
20、ring process, welding operation, additional requirements regarding condition 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 thi
21、s standard: - clauses and subclauses preceded by = indicates no additional requirements to EN 15541; - 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 part of EN 1559
22、 applies to castings made from zinc alloys produced by sand casting, permanent 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 appl
23、y to ingots, bars, billets (or other shapes) for further reprocessing, 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 place
24、s in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.
