Since our inception in 1958, innovation and materials expertise has been at our heart as an enterprise. From inventing expanded polytetrafluoroethylene (ePTFE), to the thousands of products we have developed, we have been solving problems, improving industries and changing lives - with higher protection, better durability and more comfort.
Nov 19, 2020 · (ASTM F2299) Evaluates the filtration efficiency of particles 0.1 μm in size. The challenge material used consists of latex aerosol spheres in a controlled airflow chamber: Fluid/synthetic blood penetration resistance (ASTM F1862, ISO22609)
two main global standards covering medical mask testing are ASTM F2100 and EN 14683 and the testing requirements for each is detailed in the table on page 7. ATI does not supply any equipment that can be used to test Medical Masks with the exception of within the UK where we are able to supply particle counters to assist with testing to ASTM F2299.
The procedure employed the basic particle filtration method described in ASTM F2299, with some exceptions; notably the procedure incorporated a non-neutralized challenge. In real use, particles carry a charge, thus this challenge represents a more natural state. The non-neutralized aerosol is also specified
