The Izod Impact test indicates the energy required to break notched specimens under standard conditions. It is calculated as ft-lb per inch or Kgf-cm\/cm\u00b2  of notch and is usually calculated on the basis of a one inch specimen although the specimen used may be thinner in the lateral direction.<\/font><\/p>\n

The Izod values is useful in comparing various types or grades of a plastic. In comparing one plastic with another, however, the Izod impact test should not be considered a reliable indicator of overall toughness or impact strength. Some materials are notch-sensitive and derive grater concentrations of stress from the notching operation. The Izod impact test may indicate the need for avoiding sharp corners in parts made of such materials. For example nylon and acetal-type plastics, which in molded parts are among the toughest materials, are notch sensitive and register relatively low values on the notched Izod impact test.<\/font><\/p>\n
