1.1 本试验方法涵盖了检测水和废水中肠球菌的简单程序。它基于IDEXX的专利定义基板技术（DST）。 2. 该产品名为Enterolert，利用了一种在代谢时发出荧光的营养指示剂。它可以在24小时内检测到一个最可能数（MPN）/100毫升的细菌。水中这种微生物的存在表明粪便污染和可能存在肠道病原体。 1.2 该测试方法可成功用于饮用水、水源水、休闲（淡水和海洋）水、废水和瓶装水。用户有责任确保本试验方法对未经试验基质的水的有效性。 1.3 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。 1.4 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。 1.5 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 该试验为在24小时内检测水中的肠球菌提供了一种简单可靠的方法。对于娱乐用水（淡水和海洋），进行试验以确保游泳区域的安全。Enterolert也可用于检测瓶装水、废水、地下水和饮用水。

1.1 This test method covers a simple procedure for the detection of enterococci in water and wastewater. It is based on IDEXX’s patented Defined Substrate Technology (DST). 2 This product, Enterolert, utilizes a nutrient indicator that fluoresces when metabolized. It can detect these bacteria at one most probable number (MPN)/100 mL within 24 h. The presence of this microorganism in water is an indication of fecal contamination and the possible presence of enteric pathogens. 1.2 This test method can be used successfully with drinking water, source water, recreational (fresh and marine) water, wastewater, and bottled water. It is the user’s responsibility to ensure the validity of this test method for waters of untested matrices. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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. ====== Significance And Use ====== 5.1 This test provides an easy and reliable method for the detection of enterococci in water within 24 h. For recreational water (fresh and marine) testing is performed to insure areas are safe for swimming. Enterolert also can be used for testing bottled water, wastewater, ground water, and drinking water.
