scope:

This Standard specifies the requirements for automated magnetic flux leakage examination of seamless and welded steel pipes and tubes with the exception of submerged arc-welded steel tubes (hereafter referred to as tubes).

This Standard is applicable to the inspection of tubes with an outside diameter equal to or greater than 10 mm. Unless otherwise specified by the product standard or agreed between the purchaser and the manufacturer, this Standard is applicable to the detection of predominantly longitudinal imperfections.

NOTE The International Standards corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 10893-1 : 2011 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 + Amendment 1 : 2020

ISO 10893-3 : 2011 Non-destructive testing of steel tubes - 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 + Amendment 1: 2019 + Amendment 2 : 2020 (overall evaluation : MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.
