ASTM E3363-23 - Standard Test Method for Quantitative Performance Evaluation of Antimicrobial Towelettes
Standard Test Method for Quantitative Performance Evaluation of Antimicrobial Towelettes
|Keywords:||antimicrobial towelettes; cell scraper; efficacy methods; membrane filtration; Pseudomonas aeruginosa; Quantitative Towelette Method (QTM); Staphylococcus aureus; test culture; wiping contaminated surfaces;|
1.1 This test method quantitatively determines the effectiveness of various sizes of antimicrobial towelettes in treating hard, non-porous surfaces against Pseudomonas aeruginosa and Staphylococcus aureus.
1.2 This test method may be used to evaluate towelettes for antimicrobial efficacy against additional microorganisms (with necessary modifications).
1.2.1 This test method does not differentiate between chemical inactivation of the test microbe and mechanical removal of inoculum from a surface; rather, product efficacy is considered a combination of both attributes of a towelette-based formulation.
1.3 This test method involves the use of hazardous materials, chemicals, and infectious microorganisms and therefore should be performed only by those trained in microbiological techniques in facilities designed and equipped for work with infectious agents at the appropriate biosafety level, a BSL-2 or higher laboratory; specifications provided in the “Biosafety for Biomedical and Microbiological Laboratories” (BMBL), 6th edition (BMBL).
1.4 It is the responsibility of the investigator to determine whether Good Laboratory Practices (GLP Standards—For example, 40 CFR, Part 160 of FIFRA) are required and to follow them when appropriate.
1.5 Strict adherence to the protocol is necessary for the validity of the test results.
1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.7 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.
1.8 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.
