(2) The vale shall be applied to the steel sheet and coil up to and excluding 2000 mm in width. Remarks 1. The thickness shall be measured at any point on the steel sheet and coil not less than 20 mm from a side edge. For the steel sheet and coil under 40 mm in width, measurement shall be Study of a spiral-coil EMAT for rail subsurface inspection Dec 01, 2020 · Due to the feature, the spiral-coil EMAT is normally used to measure the thickness of an object by using known shear wave velocities , , . Since the subsurface crack causes the rail in a certain region to be thin, the rail subsurface crack can be located by thickness [6] .
