1 Scope This standard specifies the system composition, radiation detector, examination environment, examination method, imaging technology, image quality, image display and observation, image assessment, examination report, image storage and procedure qualification and the like for X-ray digital radioscopic examination method of cylinder weld. This standard is applicable to the X-ray digital radioscopic examination of cylinder weld made of steel and nonferrous materials with 1.5 mm ~ 20.0 mm thick base metals. The radiographic examination technique specified in this standard is the technology of Level AB-medium sensitivity. This standard may be regarded as the reference to the X-ray digital radioscopic examination of the butt weld of other apparatus. 2 Normative References The following documents are indispensable for the application of this document.
