Test Process

Fix the sample on the instrument's sample clamp. 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 towards the target area of the sample through a tube with an inner diameter of 0.84 mm at a pressure of 16 kPa / 2 psi. Remove and visually inspect within 10s / 60s.

Basic Principle

Achieves high-pressure penetration testing of test products through high-pressure output.
