ISO 22609:2004 Clothing for protection against infectious specialists — Medical Face Masks

 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.

This International Standard doesn’t have any significant bearing for:

  • To all structures or conditions of blood-borne pathogen presentation. Clients of the test strategy should audit modes for face introduction and evaluate the suitability of this test technique for their particular application.
    • This International Standard essentially addresses the presentation of materials or certain material developments used in medical face masks This test strategy doesn’t address the presentation of the medical face mask’s structure, advancement, interfaces or various factors which can impact the general security offered by the medical mask and its movement, (for instance, filtration profitability and weight drop).
    • This test strategy doesn’t address breathability of the medical mask materials or different properties influencing the accommodation of breathing through the medical mask. This test technique assesses medical face masks as a thing of defensive attire. This test strategy doesn’t assess the presentation of medical mask as insurance against pollution through airborne introduction pathways or inside the avoidance of the infiltration of aerosolised body liquids kept on the medical face mask.

PRINCIPLE

A specimen medical mask is supported on an apparatus. A volume of engineered blood is showered on a level plane at the example cover to reenact the situation of a mask being sprinkled by a punctured vessel. the amount of liquid, separation to affect, hole size and liquid speed are characterized during this technique and expected to be as indicated by this medicinal services situation. Any proof of synthetic blood entrance on the medical mask reaching the wearer’s face comprises disappointment. Results are accounted for as “pass/come up short”.

Example medical face masks are assessed at a total of three distinct speeds like human blood weights of 10,6 kPa, 16,0 kPa, and 21,3 kPa.

Test results are reported at each velocity and therefore the medical mask is rated at the very best corresponding vital sign that medical mask specimens demonstrate a suitable quality limit of 4,0.
