The Splash Resistance test to EN 14683, in accordance with ISO 22609:2004, enables a fixed volume of synthetic blood to be directed at high velocity at the center of the mask (32 masks are required for each test of which 29 are required to pass)
The inside of the medical face mask is then observed for blood penetration.
The evaluation of a pass/fail is dependant on the velocities of the synthetic blood and the penetration that is observed following the test. The velocities correspond to a blood pressure at 80, 120 and 160 mm Hg
