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.

Apparatus for multiaxial impact-testing of a material, comprising an impact member arranged for impact with a sample of the material, wherein either the energy or the force required to rupture the sample in its weakest direction on such impact is employed as a measure of the multiaxial impact strength of the material, characterized in that relative movement of the sample and the member is maintained at a substantially constant velocity along a straight line before and after impact and is derived from angular movement of a cam driven by a flywheel.
