Bibliography

Describes specific procedures for industrial X-ray and gamma radiography for discontinuity detection purposes, using NDT (Non-destructive testing) film techniques.

This European Standard gives specific procedures for industrial X-ray and gamma radiography for discontinuity detection purposes, using NDT (Non-destructive testing) film techniques. This part of EN 12681 specifies the requirements for film radiographic testing of castings. Films after exposure and processing become radiographs with different area of optical density. Radiographs are viewed and evaluated using industrial radiographic illuminators. This part of EN 12681 specifies the recommended procedure for the choice of operating conditions and radiographic practice. These procedures are applicable to castings produced by any casting process, especially for steel, cast iron, aluminium, cobalt, copper, magnesium, nickel, titanium, zinc and any alloys of them. NOTE This European Standard considers EN ISO 5579. This part of this European Standard does not apply to: - radiographic testing of castings for aerospace applications (see prEN 2002-21); - radiographic testing of welded joints (see EN ISO 17636-1); - radiography with digital detectors (see EN 12681-2); - radioscopic testing (see EN 13068, all parts).
