Applicable for class 3 surgical face mask-(Astm level 3) class 3 surgical masks include 4 layers of construction which offer clinicians comfort, protection, and breathability that they seek. Designed for fluid protection.
Definition of splash resistance test- ‘Resistance of medical face mask to penetration by synthetic blood’. This test method is used to evaluate the resistance of medical face masks to penetration by the impact of a small volume (~2 ml) of a high velocity stream of synthetic blood.
Splash Resistance Tester-Principle
A volume of synthetic blood is disbursed at a specimen mask by a pneumatically controlled valve from a set distance at specified pressure to simulate the impact of blood or other body fluid onto the specimen. The velocity and volume of fluid are set to simulate a given health care scenario.
