The document discusses impact testing which measures a material's toughness by applying a sudden sharp load to a standardized sample. Impact testing uses equipment to apply a force over a distance to break the sample, allowing measurement of the energy absorbed before failure. Equipment options are available for metals, plastics, and high capacity testing, ranging from desktop to 20000 ft-lb machines, and use samples typically 10mm x 10mm with a notch.

1. IV.) Impact Test - you measure the energy required to break a standard sized sample with a sudden, sharp load.

2. - the impact test is used to find a material's toughness , it's ability to absorb energy without breaking.

3. Impact Test Apparatus

4. A.) Energy Measurement Energy = Force x Distance Example: Lifting a 100 lb box 5'

5. B.) Standard Sample Size 10mm x 10mm with notch

6. C.) Equipment for Metals 10mm x 10mm sample with notch 25 ft-lb to 300 ft-lb test range

7. D.) Equipment for Plastics 1ft-lb to 16ft-lb

8. E.) High Capacity Equipment Up to 20000 ft-lb

9. F.) Desktop Equipment 0.5 to 13.4 ft-lb
