Chemical disinfectants and antiseptics. Preservation of test organisms used for the determination of bactericidal, sporicidal and fungicidal activityStandardized tests for the determination of bactericidal, mycobactericidal, sporicidal and fungicidal activity of chemical disinfectants and antiseptics necessitate the use of test organisms whose purity and identity have been verified and whose biological behaviour remains stable. Therefore it is essential to specify the storage requirements. This European Standard aims at describing methods for preservation of test organisms used for such purposes.
