A method of and apparatus for testing the performance of a tool (13) for use in the humane slaughtering of animals wherein a bolt accommodated within and coaxially of a barrel of the tool (13) is adapted to be driven lengthwise of the barrel by a force applied thereto. The method and apparatus includes mounting the tool (13) on a test rig (1), firing the tool (13), detecting the time for the captive bolt to travel a pre-determined distance by means of a sensor unit (16), applying a calibration factor to the detected time to compensate for time delays and determining the actual time to travel the predetermined distance, and generating a signal representative of the condition of the tool (13) based on the actual time. |
