How do you test a an NFL football helmet for strength?

Testing an NFL football helmet for strength involves several standardized procedures to assess its impact resistance and overall durability. Helmets are subjected to various tests using drop tests, where they are dropped from specific heights onto rigid surfaces to simulate impacts during play. Additionally, they may undergo compression tests to evaluate the integrity of the materials used. These tests ensure that helmets meet safety standards set by organizations like the National Operating Committee on Standards for Athletic Equipment (NOCSAE).
