标准摘要
[中文适用范围]： 本文件规定了通过计算机射线照相（CR）或数字探测器阵列（DDA）射线照相对自动熔焊钢管的纵向或螺旋焊缝进行数字射线照相X射线检测的要求，以检测缺陷。 本文件规定了验收水平和校准程序。 也可适用于圆形空心型材的检测。 注：作为替代方案，请参阅 ISO 10893-6 以了解基于胶片的射线照相 X 射线测试。 [外文原描述]： 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.
