ISO 10893-7:2019

This document specifies the requirements for digital radiographic X-ray testing by either computed radiography (CR) or radiography with digital detector arrays (DDAs) of the longitudinal or helical weld seams of automatic fusion arc-welded steel tubes for the detection of imperfections. This document specifies acceptance levels and calibration procedures. It can also be applicable to the testing of circular hollow sections. NOTE As an alternative, see ISO 10893-6 for film-based radiographic X-ray testing.
