ABSTRACT:
A sample of material is tested by rupture with an impact member, relative movement of the sample and member being maintained at a substantially constant velocity along a straight line before and after impact and being derived from angular movement of a cam driven by a flywheel. The apparatus is capable of automatic operation (including automatic result recording) with increased operator safety, gives results of good reproducibility, and is quieter in use than previously proposed apparatus.
