Dynatup Instrumented Impact

Test ID



A Dynatup 8250 impact tower is used to impact specimens.  Samples are 4 inch square plaques or disks with thickness 1/8 inch or larger.  Sample is clamped between grips at base of apparatus.  Tup is released to impact specimen at a set velocity and energy.  Test is complete when tup penetrates specimen and stops.  Five replicates are performed.


Test can be performed with lubricated or non-lubricated tups. Non-lubricated is the default.


  • ASTM D3763
  • ISO 6603-2


Deflection at Maximum Load, Energy at Maximum Load, Failure Type, Maximum Load, Total Energy. This data appears in Matereality as Instrumented Dart Impact.


Number of times this test is repeated: 5


10 impact plaques [details]


This test is exceptionally valuable 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 fail 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.
