In accordance with section 104(b) of the Consumer Product Safety Improvement Act of 2008 (CPSIA), the U.S. Consumer Product Safety Commission (CPSC), in March 2017, published a consumer product safety standard for infant bath tubs. The standard incorporated by reference the applicable ASTM voluntary standard. The CPSIA sets forth a process for updating standards that the Commission has issued under the authority of section 104(b) of the CPSIA. In accordance with that process, we are publishing this direct final rule, revising the CPSC's standard for infant bath tubs to incorporate by reference a more recent version of the applicable ASTM standard.
