DIN EN 1371-2:2015-04

This European Standard complements the general principles of liquid penetrant testing given in EN ISO 3452-1 for the additional requirements for investment castings. It has been written to take account of the difference of dimension of the reference area and the difference of nature of discontinuities with regard to other casting processes for which EN 1371-1 is applicable. The structure of this standard is similar to that of EN 1371-1. This European Standard applies to all cast metals, except copper-tin and/or copper-tin-lead alloy castings where copper is the major constituent. It specifies a liquid penetrant testing method for castings produced by investment casting for general purposes. Liquid penetrant testing as well as any other non-destructive examination method is part of a general or specific assessment of the quality of a casting to be agreed between the manufacturer and the purchaser at the time of acceptance of the order. This European Standard has been prepared by Technical Committee CEN/TC 190 "Foundry technology", the secretariat of which is held by DIN (Germany). Regarding the German collaboration, the responsible Working Committee is NA 036-00-03 AA "Prüfverfahren für Gusswerkstoffe" ("Test methods for cast materials") at the Foundry Practice Standards Committee (GINA).
