Synthetic Blood Penetration- Splash Resistant
The Synthetic Blood Penetration – Splash Resistance test is one of two synthetic blood resistance tests offered by Nelson Laboratories to determine a product’s ability to act as a barrier to blood-borne pathogens. The Splash Resistance test method challenges medical face masks with a fixed volume of synthetic blood directed at high velocity at the center of the mask.
This test is required by ASTM F2100 and is tested in compliance with ASTM Method F1862, ASTM F2100 and EN 14683. Nelson Laboratories’ highly experienced staff provides a one-stop shop for all ASTM F2100 and EN 14683 testing.

Study OutlineIn the Synthetic Blood Penetration – Splash Resistance test procedure, specimens are conditioned for a minimum of 4 hours at 21 ± 5ºC and 85 ± 5% relative humidity. The samples are removed from the conditioning chamber and mounted on the test fixture. The synthetic blood is pumped from a pressurized container equipped with a pneumatic-controlled valve and valve controller. The controller allows the valve to dispense a specified volume of synthetic blood through a small diameter canula in a controlled amount of time.
The time in which the valve remains open is calculated from the desired blood pressure. Medical face masks can be evaluated at three different velocities corresponding to a human blood pressure of 10.6, 16.0 and 21.3 kPa (80, 120 and 160 mm Hg).
As the valve opens, synthetic blood is allowed to spray through a 0.84 mm orifice onto the surface of the medical face mask. One spray is delivered to the center of the sample at a distance of 305 mm. The pressure of the vessel is adjusted so that approximately two ml of synthetic blood are delivered with each spray.
At the conclusion of the test, the back side of the medical face mask is observed for synthetic blood penetration. The results are scored as pass or fail, depending on whether synthetic blood penetration occurred.
Please specify pressure when submitting samples:
