Final rule.

This document revises the chest jacket and spine box specifications for the Hybrid III 5th Percentile Female Test Dummy (HIII-5F). The jacket revisions resolve discrepancies between the jacket specifications in subpart O and jackets available in the field, and ensure a sufficiently low level of variation between jackets fabricated by different manufacturers. The spine box revisions eliminate a source of signal noise caused by fasteners within the box that may become loose during sled or vehicle crash tests. This rulemaking responds to a petition for rulemaking from the Alliance of Automobile Manufacturers.
