ISO 22612:2005 specifies a test method for assessing the resistance of protective clothing materials, particularly surgical drapes and gowns, to the penetration of bacteria carried by dry particles. This standard is crucial in environments where maintaining a sterile field is essential, such as hospitals, surgical theaters, and biomedical research facilities. It ensures that the materials used in protective garments can effectively act as a barrier against microbial contamination, thereby safeguarding both patients and medical personnel.

The standard focuses on the ability of the fabric to prevent the passage of dry microbial-contaminated particles, which can be shed from the skin or released into the air through movement. Unlike liquid penetration tests, ISO 22612 simulates conditions where bacteria are transmitted through air and dust in dry form, which can occur frequently in clinical or surgical settings. The test evaluates how resistant a material is to bacterial penetration under mechanical stress, such as rubbing or friction, which can commonly happen during medical procedures.

Achieving ISO 22612:2005 certification demonstrates that a product meets high-level requirements for infection control and patient safety. It enhances the credibility of manufacturers supplying personal protective equipment (PPE) and surgical textiles by confirming their products' compliance with international hygiene and performance standards. At ExpertISO, we assist organizations in understanding the test methodology, preparing the necessary documentation, and meeting all compliance requirements—ensuring that your protective garments offer trusted defense against airborne microbial threats in critical health environments.
