ASTM F2933-21 PDF Download

The ASTM F2933-21 standard specifies specifications for full-size and non-full-size crib mattresses in terms of design, testing, and labeling. This standard is applicable to play yards, non-full-size cribs, and aftermarket mattresses for cribs.

To guarantee that testing is done accurately and consistently, the standard contains provisions for calibration and standardization. Additionally, it describes specific tests that will be used to judge the effectiveness and safety of crib mattresses. Measurements of firmness, entrapment risks, and flammability, among other things, may be included in these tests.

The standard also specifies labeling standards in addition to design and testing specifications. Mattresses for cribs must be properly tagged and labeled to show that they comply with the requirement. Any crib mattress produced after the specification's approval date that does not fully adhere to the standard's specifications will be deemed non-compliant.
