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 10893-2 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 9304:1989, which has 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 hydraulic 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 2:
Automated eddy current testing of seamless and welded
(except submerged arc-welded) steel tubes for the detection of
imperfections
1 Scope
This part of ISO 10893 specifies requirements for automated eddy current testing of seamless and welded
tubes with the exception of submerged arc-welded (SAW) tubes, for the detection of imperfections according
to the different acceptance levels as shown in Tables 1 and 2. It is applicable to the inspection of tubes with
an outside diameter greater than or equal to 4 mm.
This part of ISO 10893 can also be applicable to the testing of hollow sections.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

ISO 11484, Steel products — Employer's qualification system for non-destructive testing (NDT) personnel
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 11484 and the following apply.
3.1
reference standard
standard for the calibration of non-destructive testing equipment (e.g. drill holes, notches and 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”.

3.5
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
3.6
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
3.7
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)
3.8
agreement
contractual arrangement between the manufacturer and purchaser at the time of enquiry and order
4 General requirements
4.1 Unless otherwise specified by the product standard or agreed on by the purchaser and manufacturer,
this eddy current inspection shall be carried out on tubes after completion of all the production process
operations, such as rolling, heat treating, cold forming and hot working, sizing and primary straightening.
4.2 The tubes being tested 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.
4.3 This inspection shall be carried out by trained operators qualified in accordance with ISO 9712,
ISO 11484 or equivalent and supervised by competent personnel nominated by the manufacturer. In the case
of third-party inspection, this shall be agreed on between the purchaser and manufacturer.
The operating authorization issued by the employer shall be according to a written procedure. NDT operations
shall be authorized by a level 3 NDT individual approved by the employer.
NOTE The definition of levels 1, 2 and 3 can be found in appropriate International Standards, e.g. ISO 9712 and
ISO 11484.
5 Test method
5.1 Test techniques
5.1.1 The tubes shall be tested by the eddy current method for the detection of imperfections using in
“absolute mode” and/or in “differential mode” one of the following alternative automated or semi-automated
techniques:
a) concentric coil technique — full peripheral (see Figure 1);
b) fixed or rotating probe/pancake coil technique — full peripheral (see Figure 2);
c) segment coil technique — weld seam only (see Figure 3) or full body (see
