The standard becomes effective 18 months after publication of the final rule in the Federal Register.
Stroller and Infant Carriage – ASTM Definition
ASTM F833-13b defines a stroller as a wheeled vehicle used to transport children, usually from infancy to 36 months of age. Children are transported generally sitting-up or in a semi-reclined position by a person pushing on a handle attached to the stroller. A carriage is generally used to transport an infant in a lying-down position; thus, the principal difference between strollers and carriages is the position of the occupant. Both carriages and strollers may be capable of being folded for storage.
Background of the Infant Carriage / Stroller Final Rule
On 20 May 2013, the CPSC issued a notice of proposed rulemaking (NPR) for carriages and strollers 78 FR 29279 issuing a safety standard for carriages and strollers. In the NPR, the Commission proposed to incorporate ASTM F833-13, which addresses many of the hazards patterns identified for strollers. Hazard patterns identified in the NPR included issues with wheels, parking brakes, locking mechanisms, restraints, hinges, structural integrity, stability / tip-over, clearance, car seat attachment, canopies, handlebars, seats, sharp points or edges, trays and other miscellaneous problems.
The Final Rule (2) incorporates, by reference, ASTM F833-13b with a modification to the passive containment / foot opening test method to address head entrapment hazards associated with multi-positional / adjustable grab bars.
Specifically, the test method for passive containment / foot opening is revised as follows:
- 7.12.1 Secure the front wheels of the unit in their normal standing position so that the unit cannot move forward. Attach the tray(s) or grab bar(s) in the position that creates the bounded opening(s). Position any adjustable features (that is, grab bar, calf supports, foot rests, etc.) that may affect the bounded opening(s) to create an opening(s) size that is most likely to cause failure; and
- 7.12.3 if necessary, reattach/reposition tray(s) grab bar(s), then perform the torso probe test per 7.12.4. Position any adjustable features (that is, grab bar, calf supports, foot rests, etc.) that may affect the bounded opening(s), to create the opening(s) size that is most likely to cause failure.
