YY/T 0691 Mask synthetic blood penetration tester, Synthetic blood penetration testing machine for mask
Product description
Used to determine the resistance of protective masks to synthetic blood penetration under different test pressures. It can also be used to determine the resistance of other coating materials to blood penetration.
YY/T 0691 Mask synthetic blood penetration tester, Synthetic blood penetration testing machine for mask
Applicable standard:
GB 19083, YY/T 0691, YY 0469
YY/T 0691 Mask synthetic blood penetration tester, Synthetic blood penetration testing machine for mask
Instrument characteristics
1. The convex sample fixing device can simulate the actual use state of the mask, leaving a test target area without damaging the sample, and making the synthetic blood distributed in the target area of the sample.
2. The special constant pressure injection device can spray a certain volume of synthetic blood within a controlled time.
3. The injection velocity corresponding to 10.6kPa, 16kPa and 21.3kPa of human average blood pressure can be fully simulated for the test.
4. A fixed target plate is set, which can block the high-pressure part of the injection liquid flow and only let the steady-state part of the injection flow to the sample, increasing the accuracy and repeatability of the injection liquid velocity to the sample.
