Abstract
A test device for dental instruments, which have a movably seated ram that moves toward the test subject in free flight with constant speed and after impact against the subject will return to initial position, characterized by a test member which is situated externally of the instrument and has a seating surface for engagement by the ram and an arrangement for positioning the test member on a carrier member so that it would have the elasto-mechanical properties which correspond to those of a test subject. The device includes the carrier member being a cap having the test element held by a resilient material in the cap so that the cap can be inserted onto the end of the instrument. The test element can also be a resilient tongue on the carrier member, which can have a plurality of resilient tongues forming a plurality of test members. In another embodiment, the carrier member has a slot so that the test element or member is a component part separated by the slot from the remainder of the solid body of the carrier member.
