ISO 22609:2004 depicts a research center test technique for estimating the obstruction of Medical Face Masks to entrance by a sprinkle of synthetic blood.

Workers, primarily those within the health care profession, involved in treating and caring for people injured or sick, are often exposed to biological liquids capable of transmitting disease. These diseases, which can be caused by a spread of microorganisms, can pose significant risks to life and health. this is often very true of blood-borne viruses that cause hepatitis [Hepatitis B Virus (HBV) and hepatitis C Virus (HCV)] and purchased immune deficiency syndrome (AIDS) [Human Immunodeficiency Virus (HIV)].

Since building controls can’t take out every single imaginable presentation, consideration is set on diminishing the capability of direct skin contact through the use of defensive apparel that opposes entrance. This test technique was created for positioning the engineered blood entrance obstruction execution of medical mask during a way speaking to genuine use as might happen right when the face mask is reached by a fast stream of blood from a punctured physical issue.

The test method is meant to gauge the protection of the health care provider’s face from exposure to blood and body fluids. it’s wont to evaluate the resistance of medical mask s to penetration by synthetic blood under high-velocity liquid contact with the medical face mask surface of a hard and fast volume over a comparatively short period of your time (0 s to 2,5 s). Medical mask “pass/fail” determinations are supported visual detection of synthetic blood penetration.
