17、cument (EN 1559-4:2015) has been prepared by Technical Committee CEN/TC 132 “Aluminium and aluminium alloys”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the lates
18、t by August 2015 and conflicting national standards shall be withdrawn at the latest by August 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such
19、patent rights. This document supersedes EN 1559-4:1999. Within its programme of work, Technical Committee CEN/TC 132 requested CEN/TC 132/WG 22 “Revision of EN 1559-4:1999“ to revise the following standard: EN 1559-4, Founding Technical conditions of delivery Part 4: Additional requirements for alum
20、inium alloy castings. Annex B provides details of significant technical changes between this European Standard and the previous edition. This European Standard is part of a series of standards which specify technical delivery conditions for castings. The other standards in this series are: EN 1559-1
21、, Founding Technical conditions of delivery Part 1: General; EN 1559-2, Founding Technical conditions of delivery Part 2: Additional requirements for steel castings; EN 1559-3, Founding Technical conditions of delivery Part 3: Additional requirements for iron castings; EN 1559-5, Founding Technical

DIN EN 1559-4:2015-05 EN 1559-4:2015 (E) 4 Introduction In order to assist manufacturers and purchasers to prepare proper contractual arrangements and prevent misunderstandings, CEN/TC 190 “Fo
25、undry 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 aluminium alloy casting materials and has the same structure as EN 15
26、59-1 “Founding - Technical conditions of delivery Part 1: General“. This European Standard cannot be used alone for compiling a specification for ordering and supplying aluminium alloy castings, but as a complement to EN 1559-1. The structure of this standard is as follows: clauses and sub clauses p
27、receded by indicate no additional conditions to EN 1559-1; clauses and sub clauses marked with a single dot indicate that conditions shall be agreed at the time of enquiry and order; clauses and sub clauses marked with two dots indicate that conditions can be agreed at the time of enquiry and order
28、(optional); clauses and sub clauses without a symbol are mandatory; clauses and sub clauses preceded by are supplementary to those in EN 1559-1; clauses and sub clauses preceded by completely replace those in EN 1559-1. DIN EN 1559-4:2015-05 EN 1559-4:2015 (E) 5 1 Scope This European Standard specif
29、ies the additional technical delivery conditions for aluminium alloy castings unless other conditions have been agreed at the time of enquiry and order. This European Standard retains the same structure and numbering system as used in EN 1559-1 and repeats the numbering of clauses and sub-clauses ev
30、en if nothing extra or different has been added. It also indicates items specific to aluminium alloy castings under existing or new headings. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. Fo

34、wing, patterns and tools 4.4 Information on the mass 4.5 Preliminary sample 4.6 Initial sample If required, a minimum of two initial samples shall be supplied to the purchaser for approval. If these initial samples are accepted, one shall be retained by the purchaser and one returned to the manufact
35、urer marked as “approved“. Supplementary initial samples (one for metallurgical and the other for dimensional purposes) should be retained either by the manufacturer or by the purchaser. NOTE Testing of initial samples by the manufacturer can be agreed. 5 Designations 6 Manufacture 6.1 Manufacturing
36、 process 6.2 Welding operations 6.2.1 General 6.2.2 Production welding Production welding is permitted, unless otherwise agreed at the enquiry and order stage. For railway applications, production welding has to be agreed separately (see EN 15085-2). Actions to finish castings or eliminate casting i
37、mperfections may include the use of a filler metal deposited by a suitable welding process or the insertion of a machined piece secured by welding. The manufacturers and purchasers attention is drawn to the need for approved procedures and suitably qualified welders (see EN ISO 15614-4, for finishin
38、g welding). After preparing the casting for finishing welding, the excavation can be classified in accordance with the procedure given in Annex A. 6.2.2.1 6.2.2.2 DIN EN 1559-4:2015-05 EN 1559-4:2015(E)7 6.2.2.3 6.2.2.4 6.2.2.5 6.2.2.6 7 Requirements 7.1 General 7.2 Material 7.2.1 Chemical compositi

41、g) Liquid penetrant examination shall be carried out in accordance with EN 1371-1. Radiographic inspection shall be carried out in accordance with EN 12681. Where applicable, unacceptable external and internal discontinuities shall be eliminated by production welding (see 6.2.2) or other agreed meth

The impregnati
43、on medium and method, maximum permitted size of discontinuities and retest procedures shall be agreed between purchaser and manufacturer. 7.3.4.4 In the case of as cast castings, it is recommended that the purchaser agrees with the manufacturer on the choice of any non-destructive testing and criter
44、ia to determine the acceptability of a subsequently machined surface. Unless specifically agreed, discontinuities revealed on the machined surface should not be regarded as a cause for rejection. If the porosity on machined surfaces is to be assessed, manufacturer and purchaser should agree on the m
45、ethod to be used. 7.3.5 Mass of the casting 7.3.6 Additional requirements regarding the conditions of the casting 7.3.6.1 Macrostructure Where appropriate, a macroscopic examination of a suitably prepared and etched section shall be used to assess the grain size and/or structural discontinuities of
46、a casting to agreed criteria. Assessment is usually carried out with or without low magnification. 7.3.6.2 Microstructure Where appropriate, a microscopic examination of a suitably polished and etched section shall be used to determine the metallurgical structure of a casting to agreed criteria. Ass
47、essment is usually carried out at a high magnification and includes the nature, shape and distribution of the structural constituents. NOTE A cooling curve/thermal analysis carried out on a sample of liquid alloy before casting, can predict, to a limited extent, the metallurgical structure to be exp
48、ected in the casting. 7.3.6.3 Density evaluation can be used to estimate the soundness of castings by weighting in air and water to agreed criteria.
