Repeatability and Reproducibility of a Standard Test Method for Measuring Head-Supported Mass Properties

U.S. military service members are provided protective head gear for use in training and operational environments. This headgear is typically in the form of a helmet, at a minimum consisting of a rigid outer shell and an individual fitting and retention system, which is an essential personal protective equipment (PPE) item. Many different helmet configurations are used by the U.S. soldier, depending on their military occupational series, the anticipated threat, and the operational environment.
