DRK227 Medical Mask Synthetic Blood Penetration Tester
Features: 1. The protruding sample fixing device can simulate the actual use state of the mask, leave the test target area, and does not damage the sample, and distribute the synthetic blood in the target area of the sample. 2. A special constant pressure spray device can spray a certain volume of synthetic blood within a controlled time. 3. It can fully simulate the injection speed corresponding to the average human blood pressure of 10.6kPa, 16kPa, and 21.3kPa for testing. 4. It is equipped with a fixed target plate, which can block the high-pressure edge part of the sprayed liquid flow, and only the steady-state flow part is sprayed on the sample, which increases the accuracy and repeatability of the liquid speed sprayed on the sample. Standards compliant: GB 19083-2010 Technical requirements for medical protective masks, 5.5 synthetic blood penetration barrier performance YY/T 0691-2008 Protective equipment for infectious pathogens Test method of resistance to penetration of synthetic blood for medical masks (fixed volume, horizontal spray) YY 0469-2011 Technical requirements for medical surgical masks Blood penetration test device ISO 22609:2004 Protective equipment for infectious pathogens-Test method for resistance to penetration of synthetic blood by medical masks (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) Technical Parameters: Spraying distance: 300mm～305mm adjustable Nozzle diameter: 0.84mm Jet speed: 450cm/s, 550cm/s, 635cm/s Weight: 35kg Power source: AC220V 50Hz
