ISO 22612:2005 specifies a test method for assessing the resistance to penetration through barrier materials of bacteria-carrying particles. ISO 22612 was prepared by the European Committee for Standardization (CEN) in collaboration with Technical Committee ISO/TC 94, Personal safety — Protective clothing and equipment, Subcommittee SC 13, Protective clothing, in accordance with the Agreement on technical cooperation between ISO and CEN 
This standard EN ISO 22612 describes a test method, with the associated equipment, that may be used to determine a material’s resistance to dry penetration of bacteria on particles in the size range most typical for human skin scales

Due to its complexity, this ISO 22612:2005 cannot be considered as a useful method for routine quality control but may suit the needs when a material is assessed for compliance with the requirements of current regulations such as EU Directive 93/42/EEC.
