32、 lot consignment, or part thereof, submitted for inspection, comprising products of the same grade or alloy, form, temper, size, shape, thickness or cross-section and processed in the same manner 3.3 structural property property having a direct effect on the static and dynamic load carrying capabili

33、ty of a component or assembly 4 Ordering information The order shall define the product required for structural applications and shall contain the following information: a) designation of the aluminium alloy and temper according to EN 1706; b) drawing of casting including the following indications:

34、area for X-ray-testing and the relevant acceptance criteria according to ASTM-E 155; acceptance criteria for surface imperfections according to EN 1371-1; c) reference to this European Standard (EN 13981-3); d) quantity: total mass or number of pieces; tolerances on quantity if required; e) any requ

35、irements for certificates of conformity, test and/or analysis reports or inspection certificates; f) any additional requirements agreed between supplier and purchaser. If special requirements are stated in the order agreed between supplier and purchaser which differ from requirements specified or re

36、ferenced in this document, then these special requirements shall apply. EN 13981-3:2006 (E) 7 5 Requirements 5.1 Production and manufacturing processes Unless otherwise specified on the order, the production and manufacturing processes shall be left to the manufacturers discretion. Any modification

37、of the production process qualified by the first-off procedure (see 6.1), which can affect the quality of the product shall be reported to and approved by the purchaser. In specific cases, a new first-off approval can be necessary. Unless it is explicitly stated on the order, no obligation shall be

38、placed on the manufacturer to use the same processes for subsequent and similar orders. 5.2 Quality assurance The manufacturer shall establish and maintain a quality management system which should be at least equivalent to EN ISO 9001. Furthermore, the ordering railway company may require a formal a

39、pproval of the manufacturer according to a specified procedure. The manufacturer shall establish and maintain inspection plans defining all inspections and tests to be performed on the product, the frequency of the inspections and tests and the type of record to be established. The inspection plan s

40、hall specify for each inspection or test whether it is to be performed per cast, per heat treatment batch, per inspection lot or per any other lot of importance. The inspection plan shall conform as a minimum to the test procedures and test requirements stipulated in this standard. The inspection pl

41、an shall include additional schemes for appropriate process control. If required the inspection plan shall be submitted to the purchaser for approval before the start of production. The manufacturer shall be responsible for carrying out all inspections and tests required by this standard prior to th

42、e shipment of the product. If the purchaser wishes to inspect the product at the manufacturers works, he or she shall stipulate this at the time of order. The extent of inspections shall be in accordance with Table 1. Unless explicitly stated, quality controls and inspections shall be performed on c

43、ast and/or heat treatment lots. 5.3 Chemical composition and tempers Alloys shall be selected from the following : EN AC-21000 (EN AC-AlCu4TiMg), EN AC-21100 (EN AC-Al Cu4Ti), EN AC-42100 (EN AC-Al Si7Mg0,3), EN AC-42200 (EN AC-Al Si7Mg0,6), EN AC-43000 (EN AC-Al Si10Mg), EN AC-43300 (EN AC-Al Si9Mg

44、), EN AC-44200 (EN AC-Al Si12), EN AC-51300 (EN AC-Al Mg5), (EN AC-Al Zn105i8Mg). NOTE Alloys EN AC-21000 and EN AC-21100 are very prone to high stress corrosion in the under-aged condition T64 or even T6. If alloys EN AC-21000 or EN AC-21100 are subject to stress corrosion in use, it is recommended

45、 to have them in the T4 condition (suitable for EN AC-21000 only) or in the T7 condition (suitable for both alloys). T4 condition shows good stress corrosion resistance only if the part is used at temperatures below 100 C, otherwise, the part will naturally evolve towards under-aged condition which

46、is particularly prone to stress corrosion. Any other alloy shall be qualified according to a mutually agreed procedure, which shall consider the intended joining technique and the intended use. EN 13981-3:2006 (E) 8 The chemical compositions of these alloys are specified in EN 1706. The chemical com

47、position of EN AC-AlZn10Si8Mg is specified in Annex A. In addition, the lead (Pb) content of all alloys shall be limited to a maximum of 0,05 %. The casting processes and the tempers shall be selected from those specified in EN 1706 unless otherwise agreed upon between supplier and purchaser. 5.4 Me

48、chanical properties of castings 5.4.1 Mechanical properties of castings under static loading Tensile strength, yield strength and elongation of castings shall conform to the requirements of EN 1706 unless otherwise agreed upon between supplier and purchaser and stated on the order. Tensile strength,

49、 yield strength and elongation of EN AC-AlZn10Si8Mg is specified in Annex A. The reduction according to EN 1706:1998 clause 6.3.3.2 of yield strength and tensile strength to 70 % and elongation to 50 % of the specified values is not allowed. Any area of the casting with required mechanical properties different from those specified in EN 1706 shall be designated and stated on the drawing. 5.4.2 Mechanical properties of castings under cyclic loading Gu
