• Description:
  Six specimen industrial safety helmets supplied by NIOSH were subjected to impact force by an 8 pound spherical mass, dropped from a vertical height of 5 feet, while worn on the head of a seated dummy. The purpose of these tests was to evaluate helmet-head dynamic performance by means of information obtained from 1000 frame per second x-ray cinematography, and impactor and dummy head acceleration instrumentation. Peak and average forces, force durations, component and average resultant head accelerations are reported for each helmet type. Analysis and discussion include a defined helmet-head stiffness parameter, and consideration of the data on the basis of the Mean Strain Criterion Head Injury Model. All six specimen helmets were found to function properly under the test conditions.
