【Scope of application】 Numerous examples have shown that bacteria can penetrate shielding materials with dried organic or inorganic particles, such as bacteria-carrying dander penetrating surgical gowns or gowns, and bacteria-carrying particles penetrating packaging materials during storage. The DryPenetration Resistance Dry-State Microbial Penetration Tester is used to determine the resistance of materials to bacterial penetration on dry particles within the size range of human dander. 【Relevant Standards】

1. ISO 22612 Protective clothing for infectious agents – Test method for penetration of drying microorganisms 2. YY/T 0506.5-2009 Surgical strips, surgical gowns and clean suits for patients, medical staff and instruments Part 5: Test method for penetrating microorganisms that prevent drying
