AMI standards require that isolation gowns meet stringent requirements of AATCC 42 and AATCC 127 in the critical zones in order to be labeled AAMI Level 2 or Level 3. â??There are four critical areas that must pass the AATCC testing requirements, including two areas on the front and two locations on the sleeve. If the gown passes the AATCC 42 and AATCC 127 in all locations, then the gown is qualified for use and can be labeled AAMI level 2 or level 3. FalconTEX products have been tested using an independent accredited ISO 17025:2017 facility. Test results are published below. Under FDA EUA FalconTEX products are level 1, 2 and Level 3.
