Mask Synthetic Blood Penetration Tester test method and applicable standards

 

The Mask Synthetic Blood Penetration Tester is used to measure the penetration performance of synthetic blood and other liquid-derived liquid jets to evaluate its safety protection performance. It is mainly used to test the permeability of the mask to blood, body fluids, blood pathogens (tested with Phi-X 174 antibiotic), synthetic blood and other liquids. It is suitable for the anti-liquid penetration performance of protective equipment such as gloves, protective clothing, outer covers, coveralls, boots, etc. It can also output test reports and save test data.

 

Mask Synthetic Blood Penetration Tester test method:

 

The medical mask sample is supported on the test device, and 2mL of synthetic blood with a surface tension of 0.042±0002n/m is sprayed from a sleeve with an inner diameter of 0.84mm to the mask under test in a horizontal direction at a pressure of 16kpa at a distance of 300mm. Simulate the scene where the mask is splashed by blood from the perforated blood vessel, and visually check the penetration of the synthetic blood on the other side of the mask within 10 seconds. The medical mask samples were tested with the liquid ejection pressure corresponding to the liquid ejection velocity: 450 cm/s, 550 cm/s, and 635 cm/s. Record the test results of each jet velocity, and give the maximum blood pressure corresponding to the acceptable quality level limit of 4 for medical masks.
