This part of GYS 120 specifies an ultrasonic testing method for
determining bond defects between the bearing metal and the backing. The test can be performed on metallic
multilayer plain bearings consisting of backings lined with bearing metal based
on lead and tin, with layer thickness greater than or equal to 0, 5 mm. The test is not possible within half the diameter
of the crystal from the edges of the bearing, oil holes, grooves, etc. because
of undefined reflections. In bearings with dovetail keying grooves at the bond,
the test may not be possible along the edges of the dovetails.
