<p>A collision test apparatus (20) comprises input (22) and output members (23) formed from incompressible liquids and between which is positioned a sample (24) whose impact characteristics are to be measured. A compression wave is input to the input member (22) and propagated through the sample (24) and into the output member (23). Suitable detectors (33, 34) detect the input compression wave, output compression wave and any part of the input compression wave reflected off the sample (24).</p> |
