22、red a series of material standards covering the following cast irons: grey cast irons 1; malleable cast irons 2; spheroidal graphite cast irons 3; ausferritic spheroidal graphite cast irons 4; abrasion resistant cast irons 5; austenitic cast irons 7; compacted (vermicular) graphite cast irons 8; low
23、 alloyed ferritic spheroidal graphite cast irons for elevated temperature applications 9. In order to assist manufacturers and purchasers to prepare proper contractual arrangements and prevent misunderstanding, CEN/TC 190 approved the preparation of a series of standards covering technical delivery
24、conditions. These have been prepared as separate parts. This European Standard covers the additional technical delivery conditions for all the cast iron materials, e.g. optional information, manufacturing process, welding operation, additional requirements regarding the condition of the casting, tes
25、t methods. This European Standard cannot be used alone for compiling a specification for ordering and supplying iron castings, but as a complement to EN 1559-1. The symbol against the clause reference indicates that the requirements of that clause of EN 1559-1 have to be met. BS EN 1559-3:2011EN 155

45、 7.3.3.3 The selection of a non destructive testing method is dependent on the thickness and material of the casting and the position, orientation and size of possible discontinuities in the relevant section. Different acceptance criteria can be specified for different areas of the same casting (e.g
46、. marked zone and unmarked area). Moreover, for the same area of the casting different acceptance criteria can be specified according to the non destructive methods selected. For all non destructive testing methods, the acceptance criteria (discontinuity levels) can be graded with increasing number
47、and/or extent of indications. Unless specifically agreed, discontinuities revealed on cast surfaces which are to be machined, are not to be regarded as discontinuities, when these discontinuities are totally removed by machining. Guidelines for the specification of acceptance criteria for discontinu
48、ities are given in the informative Annex A. 7.3.3.4 If applicable, the roughness of the cast or grinded surface shall be specified. EN 1370 shall be used to specify the acceptance levels and shall be subject of an agreement between the manufacturer and the purchaser by the time of acceptance of the order.
