The purpose of this study was to determine if: (a) a football helmet equipped with the Guardian Cap meets the National Operating Committee on Standards for Athletic Equipment (NOCSAE) football helmet standards and (b) if the Severity Indexes and peak accelerations produced during NOCSAE impact tests were smaller for a football helmet equipped with the Guardian Cap over-helmet padding system than for the same helmet without the Guardian Cap. A total of 54 drop impact tests were completed, 27 on the football helmet alone and 27 on the football helmet equipped with the Guardian Cap. Tests were complete on seven different locations on the helmet at four different velocities and two different temperatures as per NOCSAE test standards. The Severity Index (SI) and peak accelerations for the Guardian Cap covered football helmet were smaller than the SI and peak accelerations for the helmet alone on the NOCSAE impact tests.
