## Abstract

This document amends 49 CFR Part 572 by adding a new subpart describing a weighted version of the current Hybrid III six-year-old child size dummy (HIII-6C). The weighted dummy weighs 62 pounds, approximately ten pounds more than the current HIII-6C. The dummy will be used in compliance tests under the Federal child restraint standard to test the structural integrity of child restraints recommended for use by children weighing over 50 pounds. This document also makes a technical amendment to the child restraint standard by adding cross- references to the subpart added by today's document.
