The mask either passes or fails based on visual evidence of synthetic blood penetration. Breathability Test MIL-M-36954 C:P 3M Cupped Particulate Respirator & Surgical Mask 1860S FDA cleared for use as a surgical mask BFE (Bacterial Filtration Efficiency) > 99% and PFE (Particle Filtration Efficiency) > 95% (at 0.3m particle size) according to ASTM F2101 Fluid resistant according to ASTM F1862 at 80 mm Hg Individually wrapped to ensure you receive a clean respirator each time.

1.1 This test method is used to evaluate the resistance of medical face masks to penetration by the impact of a small volume (~2 mL) of a high-velocity stream of synthetic blood. Medical face mask pass/fail determinations are based on visual detection of synthetic blood penetration. ASTM F1862 / F1862M - 17 Standard Test Method for 5.1 This test method offers a procedure for evaluating medical face mask resistance to synthetic blood penetration that is useful in establishing claims for penetration resistance performance of medical face masks and ranking their performance. However, this test method does not define acceptable levels of penetration resistance because this determination must be made by each responsible user ASTM F2100 - 20 Standard Specification for Performance of 1.2 This specification provides for the classification of medical face mask material performance. Medical face mask material performance is based on testing for bacterial filtration efficiency, differential pressure, sub-micron particulate filtration efficiency, resistance to penetration by synthetic blood, and flammability.
