1.1 本试验方法旨在确定在洗手过程中使用抗菌洗手剂减少暂时性皮肤微生物菌群的有效性。 2. 1.2 这些程序需要掌握微生物学技术。 1.3 本试验方法可用于评估局部抗菌洗手液配方。 1.4 执行此程序需要了解与人体保护相关的法规。 3. 1.5 以国际单位制表示的数值应视为标准值；除距离外，在这种情况下，使用英寸，括号中紧跟公制单位。 1.6 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 有关更具体的预防说明，请参阅 8.2 . 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 该程序用于测试洗手配方的抗菌效果。试验配方通常设计为经常使用，以减少手上的瞬时菌群。应使用试验方法对不借助水使用的含酒精的擦手剂和其他残留制剂进行试验 E2755 .

1.1 This test method is designed to determine the effectiveness of antimicrobial handwashing agents for the reduction of transient microbial skin flora when used in a handwashing procedure. 2 1.2 A knowledge of microbiological techniques is required for these procedures. 1.3 This test method may be used to evaluate topical antimicrobial handwash formulations. 1.4 Performance of this procedure requires the knowledge of regulations pertaining to the protection of human subjects. 3 1.5 The values stated in SI units are to be regarded as standard; except for distance, in which case inches are used and metric units follow in parentheses. 1.6 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. For more specific precautionary statements see 8.2 . 1.7 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. ====== Significance And Use ====== 5.1 The procedure is used to test the antimicrobial effectiveness of handwashing formulations. The test formulations generally are designed for frequent use to reduce the transient bacterial flora on hands. Alcohol-based hand rubs and other leave-on formulations used without the aid of water should be tested using Test Method E2755 .
