    Abstract

    Radiographic acceptance tests set standards of metal soundness that are usually higher than those set by other methods of testing. There are uncertainties of testing that arise from lack of familiarity with the tests, lack of information regarding the physical significance of observed unsoundness, and from various other causes. These uncertainties work to the disadvantage of the producer. The tests are applied properly to three broad classes of structural units: (1) highly stressed units; (2) units that by virtue of the service they perform are very important; (3) units that require expensive machining.

    It is difficult to manufacture to standards required by radiographic acceptance tests unless radiography is used in developing the manufacturing technique. There is a present need for better understanding of the tests and their significance on the part of both producers and consumers.
