Notice of proposed rulemaking - This document proposes to revise the chest jacket and spine box specifications for the Hybrid III 5th Percentile Female Test Dummy
(HIII-5F) set forth in Part 572, Anthropomorphic Test Devices. The proposed jacket revisions would 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 would eliminate a source of signal noise caused by fasteners within the box that may become loose. This rulemaking responds to a petition for rulemaking from the Alliance of Automobile Manufacturers.
