DIN EN ISO 10893-7-2011 钢管无损检测.第7部分:缺陷检测用焊接钢管焊缝的数字放射性探伤法(ISO 10893-7-2011).德文版本EN ISO 10893-7-2011
Non-destructive testing of steel tubes - Part 7: Digital radiographic testing of the weld seam of welded steel tubes for the detection of imperfections (ISO 10893-7:2011); German version EN ISO 10893-7:2011
This part of ISO 10893 specifies the requirements for digital radiographic X-ray testing by either computed radiography (CR) or radiography with digital detector arrays (DDA), of the longitudinal or helically (spiral) weld seams of automatic fusion arc-welded steel tubes for the detection of imperfections. The standard specifies acceptance levels and calibration procedures.
