【Test Process】
The specimen is secured on the instrument's specimen fixture. At a distance of 30.5cm from the center of the specimen, 2ml / 60ml of synthetic blood (with a surface tension of 0.042 ± 0.002 N/m) is sprayed horizontally towards the target area of the specimen through a nozzle with an inner diameter of 0.84mm, at a pressure of 16kPa / 2psi. The specimen is then removed and visually inspected within 10s / 60s
