In November 2022, the U.S. Consumer Product Safety Commission (CPSC or Commission) published an update to the consumer product safety standard for gates and enclosures under the Consumer Product Safety Improvement Act of 2008 (CPSIA). The standard incorporated by reference ASTM F1004-22, Standard Consumer Safety Specification for Expansion Gates and Expandable Enclosures, the voluntary standard for gates and enclosures that was in effect at the time. ASTM has now issued a revised standard, ASTM F1004-25. Consistent with the CPSIA, this direct final rule updates the mandatory standard to incorporate by reference ASTM's 2025 version of the voluntary standard.
