Does someone knows if there is a transition period from ASTM F2100-21 to -23?
Do you know when we need to change the packaging label with the new Sub-micron particulate filtration efficiency, %?
Does someone tested the masks as per ASTM F3502 and what was the test result?
Any feedback will be great appreciated.
Thanks,
