In March 2014, the U.S. Consumer Product Safety Commission (CPSC) published a consumer product safety standard for carriages and strollers. The standard incorporated by reference the applicable ASTM voluntary standard. ASTM has since published two revisions to the voluntary standard for carriages and strollers. We are publishing this direct final rule revising the CPSC's mandatory standard for carriages and strollers to incorporate, by reference, the most recent version of the applicable ASTM standard.
