**【Test Procedure】**  

Secure the sample in the sample holder. At a distance of 30.5 cm from the sample center, spray 2 mL / 60 mL of synthetic blood (surface tension 0.042 ± 0.002 N/m) horizontally toward the target area of the sample through a needle with an inner diameter of 0.84 mm, at a pressure of 16 kPa / 2 psi. Remove the sample and visually inspect within 10 s / 60 s.
