DIN EN 4050-1:2012-12

This standard defines the ultrasonic inspection procedure for rolled, drawn, extruded and forged billets, bars and plates, rolled rings and forgings with a uniform square, rectangular or round cross section. It does not cover critical rotating parts in steel, titanium, titanium alloys, aluminium alloys and heat resisting alloys that are to be inspected in accordance with the technical supply conditions of the relevant EN standards or internal specifications. For products with geometries other than those described above, the test conditions and acceptance criteria shall be agreed between the manufacturer and purchaser. The European Committee for Standardization (CEN) declared the Aerospace and Defence Industries Association of Europe (ASD-STAN) responsible for the preparation of European standards (EN) for the field of aerospace. ASD became the associated body (ASB) of CEN by the agreement dated 1986-10-03. The document EN 4050-1:2011 has been prepared by ASD-STAN, Technical Section Metallic Materials, with the participation of German experts of the Aerospace Standards Committee. The responsible German standardization committee is Working Committee NA 131-01-01 AA "Stähle" ("Steels") of the Aerospace Standards Committee at DIN. According to Resolution 57/9 of Technical Committee of the advisory board of the Aerospace Standards Committee (NL) at DIN, the German Institute for Standardization, the European space industry standardization results shall be adopted into the German body of standards in both languages, German and English. Therefore, the English version is added to this German version of the EN standard.
