SH07B 450cm/s 300mm Synthetic Blood Penetration Tester For Surgical Mask

SH07B Mask Tester Synthetic Blood Penetration Tester For Surgical Mask

AApplicable standard
Medical respirator technical requirements, 5.5 synthetic blood penetration barrier performance
YY/T 0691-2008 infectious pathogen protection equipment medical mask resistance to synthetic blood penetrability test method (fixed volume, horizontal injection)
YY 0469-2011 medical surgical mask technology requires a blood penetration test device
ISO 22609:2004 infectious pathogen protection equipment medical mask test method for resistance to synthetic blood penetration (fixed volume, horizontal injection)
ASTM f1862-07 Standard Test Method for Resistance of Medical Face Masks to blot by Synthetic Blood (Horizontal Projection of Fixed Volume at a Know Velocity)

Technical indicators
1. The protruding sample fixing device can simulate the actual use state of the mask, set aside the test target area without destroying the sample, and distribute the synthetic blood in the target area of the sample.
2. The special fixed-pressure injection device can eject a certain volume of synthetic blood in a controlled time.
3. It can fully simulate the injection speed corresponding to the average blood pressure of human body of 10.6kpa, 16kPa and 21.3kpa.
4. A fixed target plate is set to block the high-pressure edge part of the injected liquid flow and only allow the steady flow part to be sprayed on the sample, which increases the accuracy and repeatability of the liquid velocity sprayed on the sample.

Principle

The mask material was tested with synthetic blood under continuous pressure, and the penetration of synthetic blood on the material was visually inspected.
