Abstract
Impact testing apparatus in which a weighted dart is dropped from a prescribed height to penetrate a test specimen when traveling at a desired velocity and level of kinetic energy, the acceleration of the dart being assisted by a spring force in the direction of travel so that the prescribed height is maintained at a minimum for a given desired velocity and the dart being guided to the test specimen by a generally tubular guide within which the dart is loosely fitted. A force transducer is located at the tip of the dart for providing impact force information as the tip penetrates the test specimen.
