ASTM F2907-21 PDF Download

Using sling carriers safely is outlined in ASTM F2907-21, a standard consumer safety specification. To reduce the danger of injury to occupants during routine use and reasonably foreseeable misuse of sling carriers, the standard defines performance standards, test procedures, and marking requirements.

The scope of the standard describes a sling carrier as a piece of fabric or sewn fabric that is made to support the torso of the caregiver while holding up to two children in an upright or reclined position. Unless the manufacturer specifies a higher weight limit, these carriers are normally worn from birth to a weight of 35 lbs.

The standard outlines numerous tests that must be carried out to guarantee the functionality and safety of sling carriers. These tests cover adhesion, occupant retention, static and dynamic load testing, as well as testing of restraint systems. The standard also offers instructions for identifying and marking sling carriers correctly so that they may be identified as meeting the required specifications.

It is significant to note that while using the sling carrier, mishaps and injuries that could result from collisions with other people or objects are not covered by the standard. The standard further states that in order to demonstrate compliance with the specification, any sling carrier created after the approval date must meet all of its requirements.
