IZOD impact testing machine unit selection

- May 29, 2019-

Impact toughness describes the toughness or fracture resistance of polymer materials under high-speed collision.Generally speaking, the impact toughness of cantilever beam impact testing machine includes two aspects: deformation capacity and fracture resistance after impact. 2. Currently, there are 4 kinds of impact strength units of pendulum impact testing machine: J/m,KJ/㎡, kg-cm/cm,ft-ib/in


J/M: joule/meter, the ratio of impact energy to thickness, commonly used in American standard

KJ/㎡ : kilojoule/square meter, ratio of impact energy to width and thickness, national standard indicates unit

Kg-cm /cm: kg-cm/cm, the same concept as j/m, is converted into units, and American standard means units

Ft -ib/in: pound - ft /in, international standard (less commonly used)

(all the four units have conversion, and our cantilever beam can meet all the units at present.)
