Non-destructive testing gives the metalcasting facility the capability of assuring the quality of a casting without destroying it. A metalcasting facility may have internal standards regarding nondestructive testing, but it is up to the customer to specify specific tests or frequency of testing. While various methods of nondestructive testing exist to measure mechanical properties, chemical composition, casting soundness or maximum service loads, a single test that encompasses all these factors does not exist. A combination of nondestructive methods may be required to document the soundness and quality of a casting. The most common methods available are described below.
