scope:

This Standard specifies the requirements for automated eddy current examination of flaws on seamless and welded steel pipes and tubes, with the exception of submerged arc-welded steel tubes (hereafter referred to as tubes). The test employs the concentric coil technique or the probe coil technique. The concentric coil technique is generally applicable to the tubes with an outside diameter of 250 mm or under.

NOTE 1 In addition to the above techniques, ISO 10893-1 and ISO 10893-2 also specify the segment coil technique. This Standard, however, does not include the said technique since it has hardly been applied in Japan.

NOTE 2 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 10893-2 : 2011 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 + Amendment 1 : 2020 (overall evaluation : MOD)

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