In November 2012, the U.S. Consumer Product Safety Commission (CPSC) published a consumer product safety standard for infant swings under section 104 of the Consumer Product Safety Improvement Act of 2008 (CPSIA). The standard incorporated by reference the ASTM voluntary standard for infant swings that was in effect at that time. The CPSIA sets forth a process for updating mandatory standards for durable infant or toddler products that are based on a voluntary standard when a voluntary standards organization revises the standard. Consistent with the CPSIA update process, in January 2021, the Commission issued a direct final rule to revise the incorporation by reference for the mandatory infant swings standard, to reflect ASTM's 2020 revised voluntary standard for infant swings. This direct final rule updates the mandatory standard for infant swings to incorporate by reference ASTM's 2021 version of the voluntary standard.
