BS ISO 20890-5:2020 pdf free download.Guidelines for in-service inspections for primary coolant circuit components of light water reactors — Part 5: Eddy current testing of steam generator heating tubes.
BS ISO 20890-5:2020 gives guidelines for pre-service inspection (PSI) and in-service inspections (ISI) by eddy current tests on non-ferromagnetic steam generator heating tubes of light water reactors, whereby the test is carried out using mechanised test equipment outwards from the tube inner side.

4 Inspection technique
4.1 Preliminary remark
The suitability of the inspection technique and the test device system shall be validated corresponding
to the requirements of the applicable regulations of the nuclear safety standard.
NOTE: The procedure for the qualification is described in ENIQ report nr.31.
A general test procedure shall be prepared. Annex A contains the items of the general test procedure;
A calibration procedure can be agreed between the contract partner and shall be documented;
The total tube circumference is recorded integrally when testing with an internal coaxial probe. The extension of indication can therefore only be determined in the axial direction. In the undisturbed area, evaluation of the signals of a frequency for determining location, depth and axial extension of ai operational change is sufficient.
