3. Click Shift to change the test speed. This video uses 450cm/s as a demonstration. Click Inflate and wait for the inflation to finish. (DThe button changes from blue to white.). Then press Spurt to fill the entire pipe with synthetic blood. hKfTextile Testing Instruments, Testing Equipment Manufacturer

g until the set time. And see if the synthetic blood goes through the center hole of the target plate. If not, adjust the height of the nozzle with the handle to make it a suitable height and remember the height with a ruler.

7. Then take the sample file and look on the other side of the mask to see if the synthetic blood seeps into it. If there's penetration, it's a failure. So don't pass. hKfTextile Testing Instruments, Testing Equipment Manufacturer
