This document specifies the requirements for the ultrasonic testing of steel castings (with ferritic structure) for highly stressed components, and the methods for determining internal discontinuities by the pulse-echo technique. Purchasers determine if components are highly stressed based on the need for performance or safety. This document applies to the ultrasonic testing of steel castings which have usually received a grain-refining heat treatment and which have wall thicknesses up to and including 600 mm. For greater wall thicknesses, special agreements apply with respect to the test procedure and the acceptance levels.Cross References:ISO 16810ISO 22232-1ISO 9712ISO 2400ISO 16811ISO 7963ISO 11971ISO 22232-2ISO 5577ISO 22232-3ISO 16827:2012EN 1559-2All current amendments available at time of purchase are included with the purchase of this document.
