**【Test Procedure】**

Fix the specimen onto the instrument's sample clamp. At a distance of 30.5 cm from the center of the specimen, use a needle tube with an inner diameter of 0.84 mm to spray 2 mL / 60 mL of synthetic blood (surface tension 0.042 ± 0.002 N/m) horizontally onto the target area of the specimen under a pressure of 16 kPa / 2 psi. Remove the specimen and visually inspect it within 10 s / 60 s.
