Instrumented Izod Pendulum Impact


Test ID  
M-426

   
Description  
A Dynatup POE 2000 apparatus is used to impact a specimen.  Specimens are bars with dimensions specified in ASTM and notched accordingly.  Sample is clamped vertically, with notch on impact side.  Machine is connected to a computer to give load deflection curve.  At set velocity and energy, pendulum is released to impact specimen.  Test is complete when pendulum completes one swing.  Five replicates are performed.    
Standards  
ASTM D256  
Data  
Izod impact strength and corresponding load-deflection traces are provided. This data appears in Matereality as Izod Impact.  
Replicates (# of times this test is repeated)  
5  
Samples  
10 - notched Izod specimens [details]

   

Application
 
This test is used as a means of quality control or materials specification. It can, in some cases, be used on a finished product to determine if the part will fracture under the set conditions. Data gathered from this test are valuable for comparative purposes, to aid the engineer in choosing an appropriate material for a specific application.
