Abstract:

FMVSS No. 218 defines the discrete size of a motorcycle helmet and requires it on the label; however, it does not specify how to measure the size. In addition, there is no standard procedure for determining the helmet positioning index (HPI) used to align the helmet on the headform for measurements and testing. This research developed procedures to determine HPI and to measure discrete size of motorcycle helmets. Four methods for measuring discrete size and one method for determining the HPI were developed and evaluated.
