Scope

1.1 To determine the bactericidal or bacteriostatic properties of porous articles treated with an active biocidal agent, samples of porous treated materials, such as textiles or paper, are inoculated with a defined suspension of microorganisms and then incubated. The changes in numbers of the bacterial populations on the treated article are compared with untreated articles either over designated time or they are compared to the initial bacterial population at “zero time” for the treated article to measure antibacterial properties. 1.2 This test method is used for measuring the quantitative antibacterial activity of porous materials that have been treated with a biocide to inhibit the growth of bacteria on the treated materials. This method may also be used to measure the ability of the treated material to inhibit the growth of a microorganism. It can measure both bactericidal and bacteriostatic activity. 1.3 This test method shall be performed by individuals experienced and adept in microbiological procedures and in facilities suitable for the handling of the microorganisms under test. 1.4 This test method 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
