ISO 10893-3:2011/Amd 1:2019

Overview

ISO 10893-3:2011/Amd 1:2019 is an important amendment to the international standard for non-destructive testing (NDT) of steel tubes. This standard focuses specifically on automated full peripheral flux leakage testing of seamless and welded ferromagnetic steel tubes (excluding submerged arc-welded tubes). The amendment modifies the dimensions of the reference notch used in testing.

This standard is published and maintained by the International Organization for Standardization (ISO), under Technical Committee ISO/TC 17, Subcommittee SC 19, which addresses steel tubes and their technical delivery conditions. The updated criteria improve defect detection accuracy in steel tube manufacturing by refining the size parameters for the reference notch.

Key Topics

• Automated full peripheral flux leakage testing: This testing method detects longitudinal and transverse imperfections in ferromagnetic steel tubes by inducing a magnetic flux and identifying leakage caused by flaws.

• Scope of tubes covered: The method applies to both seamless and welded steel tubes except those welded by the submerged arc-welding process.

• Reference notch adjustment: Amendment 1 revises the dimensions of the reference notch, specifying that:

  • The width of the reference notch shall not exceed 1 mm.
  • This change replaces the previous rule that the width could be up to the depth or 1 mm, whichever was greater.

• Non-destructive testing standards compliance: Ensures uniformity and reliability in identifying surface and subsurface imperfections affecting tube integrity without damaging the tubes.

Applications

• Quality control in steel tube manufacturing: The amendment enhances the accuracy and consistency of defect detection during the production process.

• Pipeline and structural tubing inspection: Tubes used in oil and gas, automotive, construction, and energy sectors benefit from enhanced NDT accuracy, reducing failure risks from undetected flaws.

• Safety assurance in pressure applications: As many seamless and welded steel tubes are used for pressure purposes, this NDT standard supports compliance with safety and regulatory requirements.

• Automated inspection systems: Integration with automated flux leakage testing equipment helps manufacturers increase throughput and lower manual inspection errors.

Related Standards

• ISO 10893 Series: Covers different non-destructive testing methods for steel tubes, providing comprehensive guidelines for various NDT techniques beyond flux leakage testing.

• ISO/IEC Directives Parts 1 & 2: Guides the development and maintenance of ISO standards including editorial rules followed in ISO 10893-3 amendments.

• ISO/TC 17 and SC 19 Standards: These subcommittees publish a range of standards concerning steel tube delivery conditions and testing methods, supporting safe and reliable steel tube products.

• Other ferromagnetic steel testing methods: Magnetic particle testing and eddy current testing standards complement flux leakage testing in quality assurance programs.
