ASTM E3151 – Standard Test Method for Determining Antimicrobial Activity and Biofilm Resistance Properties of Tube, Yarn, or Fiber Specimens

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.
