Effective Date Delayed to March 20, 2025
The agency delayed the effective date of the January 3, 2025 final rule until March 20, 2025. This means the amendments to 49 CFR part 572, subpart O that were published at 90 FR 250 on January 3, 2025 will not take effect until March 20, 2025, and incorporation by reference is approved as of that date.
Specifications Revised for HIII‑5F Dummy Parts
The January 3, 2025 final rule revised the chest jacket and spine box specifications for the Hybrid III 5th percentile adult female anthropomorphic test device (HIII‑5F) to address issues with fit and availability of the chest jacket and a noise artifact from the spine box. Those revised specifications apply to the HIII‑5F used in frontal compliance crash tests and air bag static deployment tests.
