Fluid-resistance test (ASTM F 1862)

Developed to simulate a challenge to the fluid splash resistance of a face mask under conditions similar to actual use. During this test, face masks are insulted with synthetic blood, and graded as a pass or fail. The masks are evaluated at fluid pressures of 80, 120, and 160mm Hg. The higher the pressure at which a mask passes, the greater the fluid splash resistance.
