Product Description

Low Temperature Brittleness Testing Machine ASTM D746
Product Description

This testing machine is used to determine the brittleness temperature of non-hard plastics by Cantilever hammer impact test method. It can determine the impact embrittlement temperature and impact embrittlement threshold temperature when the damage degree reaches 50%.
