ISO 10893-2 pdf download 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
This part of ISO 1 0893 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 1 0893 can also be applicable to the testing of hollow sections.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 1 1 484 and the following apply.
standard for the calibration of non-destructive testing equipment (e.g. drill holes, notches and recesses)
tube or length of tube containing the reference standard(s)
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”.
hollow long product open at both ends, of any cross-sectional shape
tube made by piercing a solid product to obtain a tube hollow, which is further processed, either hot or cold, into its final dimensions
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
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)
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.
