In February 2017, the U.S. Consumer Product Safety Commission (CPSC) published an update to the consumer product safety standard for toddler beds. The standard incorporated by reference the applicable ASTM voluntary standard. ASTM has since published two revised versions of the voluntary standard for toddler beds. We are publishing this direct final rule revising the CPSC's mandatory standard for toddler beds to incorporate by reference, the most recent version of the applicable ASTM standard.
