Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 10893-8 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 19, Technical
delivery conditions for steel tubes for pressure purposes.
This first edition cancels and replaces ISO 10124:1994, ISO 11496:1993 and ISO 13663:1995, which have
been technically revised.
ISO 10893 consists of the following parts, under the general title Non-destructive testing of steel tubes:
⎯ Part 1: Automated electromagnetic testing of seamless and welded (except submerged arc-welded) steel
tubes for the verification of leaktightness
⎯ Part 2: Automated eddy current testing of seamless and welded (except submerged arc-welded) steel
tubes for the detection of imperfections
⎯ Part 3: Automated full peripheral flux leakage testing of seamless and welded (except submerged
arc-welded) ferromagnetic steel tubes for the detection of longitudinal and/or transverse imperfections
⎯ Part 4: Liquid penetrant inspection of seamless and welded steel tubes for the detection of surface
imperfections
⎯ Part 5: Magnetic particle inspection of seamless and welded ferromagnetic steel tubes for the detection of
surface imperfections
⎯ Part 6: Radiographic testing of the weld seam of welded steel tubes for the detection of imperfections
⎯ Part 7: Digital radiographic testing of the weld seam of welded steel tubes for the detection of
imperfections
⎯ Part 8: Automated ultrasonic testing of seamless and welded steel tubes for the detection of laminar
imperfections
⎯ Part 9: Automated ultrasonic testing for the detection of laminar imperfections in strip/plate used for the
manufacture of welded steel tubes
⎯ Part 10: Automated full peripheral ultrasonic testing of seamless and welded (except submerged
arc-welded) steel tubes for the detection of longitudinal and/or transverse imperfections

Non-destructive testing of steel tubes —
Part 8:
Automated ultrasonic testing of seamless and welded steel
tubes for the detection of laminar imperfections
1 Scope
This part of ISO 10893 specifies requirements for automated ultrasonic testing for the detection of laminar
imperfections
a) in the pipe body (full peripheral testing) of seamless and welded, except submerged arc-welded (SAW),
steel tubes, or
b) in the area adjacent to the weld seam of welded steel tubes, and optionally
c) at the ends (full peripheral testing) of seamless and welded tubes.
This part of ISO 10893 can also be applicable to the testing of circular hollow sections.
NOTE For welded tubes, see ISO 10893-9 for an alternative test method for the detection of laminar imperfections in
steel strip/plate prior to tube forming.
2 Normative references

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 5577 and ISO 11484 and the
following apply.
3.1
reference standard
standard for the calibration of non-destructive testing equipment (e.g. drill holes, notches, recesses)
3.2
reference tube
tube or length of tube containing the reference standard(s)
3.3
reference sample
sample (e.g. segment of tube, plate or strip) containing the reference standard(s)
NOTE Only the term “reference tube” is used in this part of ISO 10893, also covering the term “reference sample”.
3.4
laminar imperfection
imperfection located in the wall thickness and generally parallel to the pipe surfaces
NOTE Its extension can be calculated by measuring its outlined area on the external surface.
3.5
tube
hollow long product open at both ends, of any cross-sectional shape
3.6
seamless tube
tube made by piercing a solid product to obtain a tube hollow, which is further processed, either hot or cold,
into its final dimensions
3.7
welded tube
tube made by forming a hollow profile from a flat product and welding adjacent edges together, and which
after welding can be further processed, either hot or cold, into its final dimensions
3.8
manufacturer
organization that manufactures products in accordance with the relevant standard(s) and declares the
compliance of the delivered products with all applicable provisions of the relevant standard(s)
3.9
agreement

4 General requirements
4.1 Unless otherwise specified by the product standard or agreed on by the purchaser and manufacturer,
an ultrasonic testing shall be carried out on tubes after completion of all the primary production process
operations (rolling, heat treating, cold and hot working, sizing and primary straightening, etc.).
4.2 The tubes under test shall be sufficiently straight to ensure the validity of the test. The surfaces shall be
sufficiently free of foreign matter which can interfere with the validity of the test.
