BS EN ISO 10893-1:2011 pdf download.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.

BS EN ISO 10893-1:2011 specifies requirements for automated electromagnetic testing of seamless and welded steel tubes, with the exception of submerged arc-welded (SAW) tubes, for verification of hydraulic leak-tightness. It is applicable to the inspection of tubes with an outside diameter greater than or equal to 4 mm, when testing with eddy current, and greater than 10 mm when testing with flux leakage method.

BS EN ISO 10893-1:2011can also be applicable to the testing of hollow sections.
5.1.4 When testing seamless or welded tubes using the fixed or rotating probe/pancake coil eddy current technique or the fixed or rotating magnetic transducer flux leakage technique, the tube and the probes/pancake coils/magnetic transducer shall be moved relative to each other or the movement shall be simulated by electronic commutation through the individual probes composing the pancake, such that the whole of the tube surface is scanned with coverage calculated on the dimensions of probe/pancake coils and magnetic transducers. There is no restriction on the maximum outside diameter using these techniques.
5.1.5 When testing seamless and welded tubes using the multiple concentric magnetic transducer technique, the tube and the multiple transducer assembly shall be linearly moved relative to each other such that the whole of the tube surface is scanned with coverage calculated on the dimensions of probe/pancake coils and magnetic transducers. There is no restriction on the maximum outside diameter using this technique.
