Macrostructure and pollution Macrostructure of steel bars on the other 14-1-2693-79 should not have shrinkage and looseness, bubbles, cracks, inclusions and delaminations are visible without using the magnifying devices. Rejection feature is the presence of a signal from the defect, the amplitude of which is greater than or equal to the amplitude of the signal reflected from the reference reflector with a diameter of 3.0 mm reference sample sensitivity set on the same with a tolerance of minus 10% or a greater depth.
