Annotation

This test method covers a uniform procedure for radioscopic examination of weldments. Requirements expressed in this test method are intended to control the quality of the radioscopic images and are not intended for controlling acceptability or quality of welds. It applies only to the use of equipment for radioscopic examination in which the image is finally presented on a television monitor for operator evaluation. The examination may be recorded for later review. It does not apply to fully automated systems where evaluation is automatically performed by computer. Unless otherwise specified by the applicable job order or contract, radioscopic examination shall be performed in accordance with a written procedure which includes: material and thickness range to be examined; equipment to be used, including specifications of source parameters and imaging equipment parameters; examination geometry, including source-to-object distance, object-to-detector-distance and orientation; image quality indicator designation and placement; test-object scan plan, indicating the range of motions and manipulation speeds through which the test object shall be manipulated in order to ensure satisfactory results; image-processing parameters; image-display parameters; and image storage.
