Scope

1.1 This test method is designed as an in vitro, quantitative assay to evaluate the antimicrobial activity of specimens with tubular geometries or small segments of yarn or fibers that have been treated with an antimicrobial agent. Further, the method was designed to provide a quantitative assessment of a specimen’s ability to resist microbial colonization and subsequent biofilm formation relative to an untreated control specimen. 1.1.1 The difference in number between the planktonic microbial population recovered from the treated test specimen and the population recovered from the control test specimen is the measure of the antimicrobial activity. 1.1.2 The measure of the ability of the treated test specimen to resist biofilm development is the difference between the adhered microbial population recovered and the adhered microbial population recovered from the control test specimen. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 Testing is to be performed by individuals trained in microbiological techniques under appropriately controlled conditions to ensure the integrity of results and personnel safety. 1.4 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
