1.1 本试验方法旨在定量评估地毯消毒溶液的抗菌和抗真菌活性。 1.2 疗效报告为活菌和真菌对数减少。 1.3 测试中使用的细菌是 金黄色葡萄球菌 , 产气肠杆菌 和 铜绿假单胞菌 . 使用的模具为 巴西曲霉 . 1.4 本试验方法要求具备微生物技术知识。 1.5 单位- 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 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。 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 当地毯暴露在环境或行人中时，在其使用寿命内会积聚土壤和生物污染物。虽然常规抽真空可以有效去除干燥的颗粒土壤，但对清除或杀死累积和嵌入的生物污染物的效果有限。在本试验方法中，描述了评估试验物质对地毯消毒能力的步骤。 5.2 本试验方法比较了惰性对照溶液和消毒试验溶液减少接种在地毯样品上的活菌和真菌的能力。 5.3 本试验方法提供了从接种的地毯中有效回收存活细菌的方法。

1.1 This test method is designed to evaluate quantitatively the antibacterial and antifungal activity of solutions for sanitizing carpets. 1.2 Efficacy is reported as the log reduction in viable bacteria and fungi. 1.3 The bacteria used in the test are Staphylococcus aureus , Enterobacter aerogenes , and Pseudomonas aeruginosa . The mold used is Aspergillus brasiliensis . 1.4 Knowledge of microbiological techniques is required for this test method. 1.5 Units— The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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. 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 Carpet, when exposed to the environment or foot traffic, accumulates soil and biocontaminants during its in-service life. While routine vacuuming may effectively remove dry particulate soils, it has a limited effect on removing or killing accumulated and embedded biocontaminants. In this test method, steps are described to assess test substances for the ability to sanitize carpet. 5.2 This test method compares an inert control solution to a sanitizing test solution for the ability to reduce viable bacteria and fungi inoculated onto carpet samples. 5.3 This test method provides for efficient recovery of surviving bacteria from inoculated carpets.
