ASTM International has published ASTM F1004 – 18 Standard Consumer Safety Specification for Expansion Gates and Expandable Enclosures on June 29, 2018.

This standard covers minimum safety performance requirements, test methods, and requirements for labeling and instructional material of expansion gates and expandable enclosures.

The standard defines expansion gates and expandable enclosures as:

  • Expandable enclosures are a self-supporting barrier intended to surround an area or play-space within which a young child may be confined
  • Expansion gate is a barrier intended to be erected in an opening, such as a doorway, to prevent the passage of young children, but which can be removed by older persons who are able to operate the locking mechanism.

These products are intended for young children aged six months through 24 months.
