Medical mask synthetic blood penetration tester main features:
1. The protruding sample fixing device can simulate the actual use state of the mask, leave the test target area, and do not damage the sample, and make the synthetic blood distributed in the sample target area.
2. Special constant pressure injection device can spray a certain volume of synthetic blood within a controlled time.
3, can fully simulate the human body’s average blood pressure of 10.6kPa, 16kPa, 21.3kPa corresponding jet speed to carry out the test.
4, fixed target plate, can block the high pressure along part of the jet liquid flow, only let the steady-state flow part of the jet to the sample, increase the accuracy and repeatability of the jet liquid speed on the sample.
Mask synthetic blood penetration tester meets the standards:
GB 19083-2010 Medical protective masks technical requirements, 5.5 synthetic blood penetration barrier performance
Test method for penetration of synthetic blood by medical masks for protection against Infectious pathogens (Fixed volume, Horizontal Jet)
YY 0469-2011 Surgical masks require blood penetration test equipment
ISO 22609-2004 Medical masks for protection against infectious pathogens – Test method for resistance to synthetic blood penetration (Fixed volume, Horizontal Jet)
ASTM F1862-07 Standard Test Method for Resistance of Medical Face Masks to Penetration by Synthetic Blood (Horizontal Projection of Fixed Volume at a Know Velocity)
