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.
