Used to test the highest temperature called brittleness temperature when the specimen is broken by impact
in prescribed conditions. Applied for non-rigid plastic and other flexible materials at low temperatures and
also test the brittleness temperature and low temperature performance for different rubber material or
different formula vulcanized rubber.
