ASTM Standardized Izod Impact Test for Polymers

Polymer products have a natural tendency of cut-growth phenomenon. According to which if plastic product or components have a cut on its surface which may be a part of design or may be an impact result, it will eventually grow with constant impacts. The resistance to such impacts is test using Izod impact tester which follows ASTM test standards. The machine helps evaluate the result of free falling impact on plastic material in real life.


Izod impact test for polymers is the most vital test process when we are talking about the quality of plastic and its strength. Based on the test results the polymer are categorized and placed under distinct applications.

Izod Impact is a solitary point test that estimates a materials resistance against a swinging pendulum. Izod impact is characterized as the dynamic energy expected to start a break and proceed with the crack until the point that the sample is broken. Izod samples are indented to counteract degradation of the specimen upon impact. This test can be utilized as a brisk and simple quality control check to decide whether a material meets particular impact properties or to analyze materials for general sturdiness.

The machine is produced under different Test Standards ASTM D256 – 10, ASTM D618 – 13, ASTM D883 – 12, ASTM D1204 – 14, ASTM D1248 – 12, ASTM E691 – 14. Microchip based display for precise test outcomes. Display for impact vitality and point of test sample. Isolate installations for Izod and Charpy test. Profoundly exact test results under Impact powers. Solid grasping apparatuses for Izod/Charpy tests. Electromagnetic Pendulum discharge component. Inbuilt alignment facility to conduct precise Izod impact test for polymers.

The test is huge in testing and assessing the impact opposition of different plastic items. It is utilized to decide the vitality that is required to break a standard test sample utilizing the pendulum technique. This exceptionally dependable instrument is an unquestionable requirement for all plastic testing research facilities and quality control divisions.
