Overview

EN ISO 10893-11:2011/A1:2020 is an amendment to ISO 10893-11:2011 published/endorsed by CEN in 2020. It covers automated ultrasonic non-destructive testing (NDT) of the weld seam of welded steel tubes for the detection of longitudinal and/or transverse imperfections. The amendment updates ultrasonic test frequency ranges and modifies acceptance/retest criteria to align inspection practice with current ultrasonic probe capabilities and quality assurance needs.

Key topics and requirements

• Scope: Automated ultrasonic testing (AUT) focused on the weld seam of welded steel tubes for detecting longitudinal and/or transverse imperfections.
• Amendment references:
  • Section 5.5 (test frequencies):
    • Shear waves: 1 MHz to 15 MHz (unchanged in range start, clarified for shear waves).
    • Lamb waves: extended from 0.3 MHz–1 MHz to 0.3 MHz–5 MHz, allowing a broader selection of Lamb-wave probe frequencies depending on tube condition, thickness and surface finish.
  • Section 8.2 (retest/acceptance procedure):
    • Revised retest rule: one retest is now permitted - “If after one retest all signals are lower than the trigger/alarm level, the tube is deemed to have passed; otherwise it is designated as suspect.” (Previously two retests were specified.)
• Practical implication: inspectors and test engineers must select probe frequencies appropriate to material condition and geometry and apply the updated single-retest acceptance criterion in automated weld inspections.
• Administrative: Approved by CEN (EN ISO 10893-11:2011/A1:2020) and to be implemented as a national standard by CEN members.

Applications

• Quality control and production inspection of welded steel tubes used in:
  • Pipes and pipelines
  • Pressure vessel and boiler tubing
  • Structural and mechanical tubing
  • Automotive and mechanical components using welded tube assemblies
• Typical uses:
  • Automated inline inspection during manufacturing
  • Final acceptance testing prior to shipment
  • Condition assessment of welded seams where longitudinal/transverse defects are a concern

Who should use this standard

• NDT engineers and technicians (ultrasonic testing specialists)
• Tube and pipe manufacturers and fabricators
• Quality assurance/quality control (QA/QC) managers
• Third‑party inspection bodies and certification agencies
• Procurement/specification authors and design engineers specifying weld seam inspection requirements

Related standards

• ISO 10893 series (other parts covering different NDT methods and tube types)
• Relevant ultrasonic testing and NDT practice standards (ISO/ASTM/EN UT guidance) - consult your national standards body for endorsed cross‑references.
