Abstract

Along with an ultrasound test apparatus for elongated test specimens (20) having cross sections that are constant throughout their length, in particular pipes and rods, which pass longitudinally along a test line (24) and thereby pass through a test machine (28) which is arranged on the test line (24), a second test machine (34) is provided. Both test machines (28, 34) are arranged on a pivot mount (30) at some distance from each other, parallel to each other and rotated 180.degree. with respect to each other, rotatable by at least 180.degree. around an axis of rotation (38), the axis of rotation running at a right angle to the test line (24) and at some distance from it, so that in an initial rotation position of the pivot mount (30) the one test machine (28) is positioned on the test line (24) and the other test machine (34) can be changed over, and in the second rotation position the other test machine (34) is positioned on the test line ( 24) and the first test machine (28) can be changed over.
