A testing device for use in determining the uncertainty of measurement of a coordinate-measuring instrument comprises a support which can be placed on the measurement table of the coordinate-measuring instrument; the support contains a plurality of locating fastening elements which receive a test standard in different orientations within the measurement range of the coordinate-measuring instrument. The test standard is a ball rod which has a ball fixed to the opposite ends of an elongate body. One end of the ball rod is mounted to the support in a pivot/swivel bearing that is so structured as to permit free measuring-probe access to contact the ball at the thus-mounted end of the ball rod.
