The U.S. Consumer Product Safety Commission (CPSC) previously published consumer product safety standards for non-full-size baby cribs (NFS cribs) and play yards under section 104 of the Consumer Product Safety Improvement Act of 2008 (CPSIA). The standards incorporated by reference the ASTM voluntary standard for NFS cribs and play yards, with modifications. ASTM recently revised the voluntary standard for NFS cribs and play yards. The CPSIA provides a process for when a voluntary standards organization updates a standard that the Commission incorporated by reference in a section 104 rule. Consistent with that process, this direct final rule revises the mandatory standards for NFS cribs and play yards to incorporate by reference the updated version of the ASTM standard.
