This European Standard gives specific procedures for industrial X-radiation and gamma radiography for flaw detection purposes, using film techniques, applicable to castings, especially of steel and iron, magnesium and zinc, of copper and nickel based alloys, and aluminium and titanium alloys. Acceptance criteria are not part of this standard. This standard does not apply to radioscopical applications (real time inspection.
