ASTM-E3162:2018 Edition

1.1 To determine the durability of standard antibacterial treatments on textile products such as apparel, piece goods, household articles, hereinafter referred to as “textile” or “textile products” to multiple home launderings.

1.2 This practice subjects textile products treated with antimicrobial agents to multiple simulated and accelerated home launderings under defined parameters such that reproducible and reliable antimicrobial analysis can be performed using standard industry accepted protocols.

1.3 For some antimicrobial agents, the durability of antibacterial properties resulting from exposure to detergent solution and abrasive action of multiple home launderings has been shown to be approximated by one 45-minute laundering cycle. The exact correlation between expressed laundry care instructions and exposure conditions identified in the practice should be determined separately for every antimicrobial agent.

1.4 The subsequent microbiological methods shall be performed by individuals experienced and adept in microbiological procedures and in facilities suitable for the handling of the microorganisms under test.

1.5 This standard may involve hazardous materials, operation, 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.

1.6 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.
