Testing method of mask synthetic blood penetration tester
Standards:
GB19083-2010: Medical protective mask technology;
YY 0469-2011: surgical masks;
YY / T0691-2008: Test method for resistance to synthetic blood penetration of medical masks for infectious pathogen protective equipment (fixed volume, horizontal spray)
EN 14683-2019 Medical face masks - Requirements and test methods
ASTM F2100-19 Standard Specification for Performance of Materials Used in Medical Face Masks
ASTM F1862 Standard Test Method for Resistance of Medical Face Masks to Penetration by Synthetic Blood (Horizontal Projection of Fixed Volume at a Known Velocity)
Summary of Test Method (ASTM F1862)1.A volume of synthetic blood is disbursed at a specimen mask by a pneumatically controlled valve from a set distance to simulate the impact (splatter) of blood or other body fuid onto the specimen. The velocity and volume of fluid are set to simulate a given healthcare scenario.
2.Any evidence of synthetic blood penetration on the inner facing of the medical face mask (side contacting the wearer's face) constitutes a failure. Results are reported as pass/fail.
3.Specimen medical face masks are evaluated at velocities of 450, 500, and 635 cm/s. These correspond to the velocity exiting a small arterial puncture at human blood pressures of 10.7, 16.0, and 21.3 kPa (80, 120, and 160 mmHg). Test results are reported at each velocity or corresponding pressure, and the medical face mask is rated at the highest corresponding blood pressure for which medical face mask specimens demonstrate an acceptable quality limit of 4.0.
