Hello dear The impact strenght  standard method can be found in the ASTM, usually is ASTM D-256.

Izod ( notched and un-notched) or falling ball

Hello Cornelius,

You can search the standard methods below. They have been used for detecting the impact resistance of biocomposites in the literature:

ASTM D3763  Standard Test Method for High Speed Puncture Properties of Plastics Using Load and Displacement Sensors

ISO 179 Determination of Charpy impact properties

ASTM D5628 Standard Test Method for Impact Resistance of Flat, Rigid Plastic Specimens by Means of a Falling Dart (Tup or Falling Mass)

ASTM D256 Standard Test Methods for Determining the Izod Pendulum Impact Resistance of Plastics.

Best Regards...

Hello, I have used standard ASTM D 256 for Impact testing for coir fiber composite.
