YY/T 0691-2008 Clothing for protection against infectious agents.Medical face masks.Test method for resistance against penetration by synthetic blood(fixed volume,horizontally projected) (English Version)
This standard provides laboratory test methods for testing the penetration performance of medical masks against synthetic blood splash. This standard is mainly used to evaluate the performance of materials or certain structures used to make medical masks. This standard does not evaluate the design, structure, interface or other factors that can affect the overall protective capabilities of medical masks (such as filtration efficiency and pressure drop). This test does not evaluate the breathability of the medical mask or other properties that affect the breathing comfort of the medical mask. This test evaluates the protective performance of medical masks. This test does not evaluate the protective capabilities of medical masks against airborne transmission or penetration of aerosols formed by body fluids deposited on the surface of the medical mask.
