In Jun 2020, American Society for Testing and Materials (ASTM) published latest ASTM F2088 - 20 for ‘Standard Consumer Safety Specification for Infant and Cradle Swings’.

This consumer safety specification is intended to minimize the risk of injuries to infants resulting from normal use and reasonably foreseeable misuse or abuse of swings. It is not intended to address all incidents and injuries resulting from the interaction of other persons with the infant in the swing.

The significant changes between ASTM F2088 - 20 and ASTM F2088 - 19 are as follows:

1. Add scope 1.3 this consumer safety specification covers products with a powered mechanism used for the purpose of providing a swinging or gliding seat in any direction relative to the frame (that is, front to back, side to side, arc, etc.) for a child who cannot climb out of the product. The powered mechanism can be through batteries, AC adapter, wind-up mechanism, or other means. This specification does not cover products that are intended to provide sleeping accommodations for the occupant.
2. Add general requirements 5.8 all protective components that are accessible to a child in the product or accessible to a child from any position around the product shall be evaluated.
3. Add general requirements 5.11 cradle swings or combination swings in a cradle swing use, mode, or position while in the rest (non-rocking) position shall comply with the requirements of Consumer Safety Specification F2194.
4. Add performance requirements 6.5 cradle swings and combination swings when in all manufacturer’s use positions as a cradle swing shall not have a restraint system.
