On March 22, 2000, NHTSA published a final rule adding a new, more advanced 3-year-old child dummy to the regulation for Anthropomorphic Test Devices. Four organizations filed petitions for reconsideration of this rule. In response to these petitions, this document makes several minor changes to the final rule, including: Slightly raising the limit on the peak forces that occur in the transition compression zone referenced in calibration tests for the dummy's thorax response; revising the impact probe definition to include provisions for mounting suspension hardware if a cable system is used to suspend and guide the pendulum for impacts, to adopt a lower minimum mass moment of inertia, and to clarify the specification for free air resonant frequency; revising specifications in several drawings for the fabrication of load cells; and correcting several
minor specification errors in these drawings.
This document also denies a request to add a provision for post-test calibration of the dummy.
The amendment is effective on January 14, 2002.
Petitions for reconsideration of the final rule must be received by January 28, 2002.
