    Can any one let me know whether IRIS is a reliable method or not for scanning fin fan coolers?

    The liquid flowing inside the cooler is Diesel and Kerosene. Is there any reference standard for IRIS?

    Please find the attached file which contains the data of the tubes and let me know whether IRIS is really reliable or not.

    IRIS is basically UT. It gives you thickness readings of the tube. The only downside is the tube internals needs good cleaning for IRIS to give good readings. For Diesel and Kerosene, cleaning shouldn’t be a problem.
    For purposes of scanning, MFL (magnetic flux leakage) would be more appropriate. It however does not give thickness readings but only a percentage of wall loss. It is a faster scanning tool, though
