This test method is designed to evaluate the resistance of non-leaching antimicrobial treated specimens to the growth of microbes under dynamic contact conditions.

The dynamic shake flasks in which all the samples are shaken in a wrist action shaker to ensures good contact between the bacteria and the treated fiber, fabric, or other substrate by constant agitation of the test specimen in a bacterial suspension during the test period.

Microbial concentrations in the treated and untreated samples are determined at zero as well as 1 or 24 hrs contact time or time specified by the sponsor.

Organisms: Klebsiella pneumoniae, ATCC No. 4352. Other organisms like Staphylococcus aureus , E.coli may be tested upon request.

Sample Requirements: Between 0.5 and 2.0 grams

Contact time: 1 hr. unless a different contact time is specified

Turn around time: 5 to 8 days
