Standards

  This standard specifies requirements for the ultrasonic testing of the weld seam of electric resistance and induction welded steel tubes for the detection of predominantly radial longitudinal imperfections, according to two different acceptance levels.

This part of ISO 10893 specifies requirements for the automated ultrasonic shear wave (generated by conventional or phased array technique) testing of the weld seam of submerged arc-welded (SAW) or electric resistance and induction-welded (EW) steel tubes.

For SAW tubes, the test covers the detection of imperfections oriented predominantly parallel to or, by agreement, perpendicular to the weld seam or both.

For EW tubes, the test covers the detection of imperfections oriented predominantly parallel to the weld seam. In the case of testing on longitudinal imperfections, Lamb wave testing can be applied at the discretion of the manufacturer.

For the detection of imperfections at the weld seam of EW tubes, full peripheral ultrasonic testing is possible. This part of ISO 10893 can also be applicable to the testing of circular hollow sections.

NOTE For full peripheral ultrasonic testing of seamless and welded (except SAW) tubes, see ISO 10893-10. 

This standard specifies requirements for the ultrasonic testing of the weld seam of submerged arc-welded (longitudinally or spirally) tubes for the detection of imperfections oriented predominantly parallel to and/or at right angles to the weld seam, according to three different acceptance levels (see table 1 and table 2).  This standard covers the inspection of tubular products with outside diameter greater than or equal to 150 mm. 

This standard specifies requirements for ultrasonic thickness testing of seamless and welded tubes for pressure purposes, with the exception of submerged arc-welded (SAW) tubes, for verification of hydraulic leak-tightness.

This International Standard specifies requirements for automated ultrasonic shear-wave (generated by single element probes or the phased-array technique) testing of seamless and welded (except submerged arcwelded) steel tubes, for verification of hydraulic leak-tightness. 

The testing technique is applied for the detection of predominantly longitudinal imperfections. Where applicable, Lamb-wave testing may be applied at the discretion of the manufacturer.

This International Standard is applicable to the inspection of tubes with an outside diameter greater than or equal to 10 mm, and with an outside diameter-to-thickness ratio greater than or equal to 5.

This standard specifies requirements for full peripheral ultrasonic thickness testing of seamless and hot-stretch-reduced welded steel tubes.

This part of ISO 10893 specifies requirements for the automated full peripheral ultrasonic testing of seamless and welded steel tubes, with the exception of submerged arc-welded (SAW) tubes, for wall thickness measurement. It specifies the testing method and corresponding calibration procedures.

NOTE 1 Full peripheral testing does not necessarily mean that 100 % of the tube surface is scanned.

NOTE 2 This test can be carried out simultaneously with full peripheral ultrasonic testing for the detection of laminar imperfections (see ISO 10893-8) using the same ultrasonic transducers for both inspection requirements.

Under these circumstances, the minimum lamination size under detection determines the percentage of the tube surface for scanning, according to ISO 10893-8. This part of ISO 10893 can also be applicable to the testing of circular hollow sections.

This part of ISO 10893 is applicable to the thickness measurement of tubes with a specified outside diameter equal to or greater than 25,4 mm and a minimum wall thickness of 2,6 mm, unless otherwise agreed on. 

This standard describes the qualification and certification of personnel engaged in non-destructive testing (NDT) of seamless and welded steel tubes, including flat products used in the manufacture of welded tubes, for pressure purposes. It specifies the training, qualification and certification requirements for three levels of NDT personnel competence to execute specific tasks in the NDT of seamless and welded steel tubes, including the weld seam, and flat products used in the manufacture of welded tubes.

This document specifies an employer’s qualification system for non-destructive testing (NDT) personnel performing the testing of the following steel products under the employer’s responsibility:

a) tubes/pipes (seamless or welded);

b) flat products, long products, rails, bars, sections, rods and wires.

This document specifies qualification requirements for the competence of Level 1 and Level 2 NDT personnel to execute specific tasks in the NDT of steel products. The qualification is issued by the employer for a specific steel product and a specific test method.

This document is applicable to NDT personnel performing predominantly the automated testing of steel products, using any of the following NDT methods:

a) eddy current testing (ET);

b) leak testing (LT);

c) liquid penetrant testing (PT);

d) magnetic testing (MT);

e) radiographic testing (RT);

f) ultrasonic testing (UT

This standard specifies requirements for full peripheral ultrasonic testing of the ends of seamless and welded tubes for the detection of laminar imperfections. It is intended to detect, over a zone at the ends of plain end and bevelled end tubes, laminar imperfections which may interfere with subsequent fabrication operations (e.g.) welding, ultrasonic inspection of welds, etc). This standard is applicable to the inspection of tubes with an outside diameter greater than 30 mm. No lower limit of thickness is specified, but see note 1.
