Impact Testing Methods

The most common drop weight impact testing methods include:

Puncture resistance test
CAI test (Compression After Impact)
Tensile impact test
3-point bending test
Wedge peel impact test.

These tests evaluate the toughness of polymers, load-deflection curves,
and total energy absorption during impact events.
