ISO 10705-3:2003规定了评估水中噬菌体浓度方法性能的一般原则。对于预计含有<；每毫升3个pfp（斑块形成颗粒）。浓缩方法可适用于所有类型的水，前提是悬浮固体和/或溶解物质的数量和性质不会干扰浓缩程序。 ISO 10705-3:2003没有给出浓缩方法的具体细节，但概述了评估特定方法对给定类型和体积水的适用性的基本原则。附录A给出了令人满意的方法示例及其应用领域。

ISO 10705-3:2003 specifies the general principles for assessing the performance of methods for the concentration of bacteriophages from water. Concentration is recommended for those water samples expected to contain < 3 pfp (plaque-forming particles) per millilitre. Concentration methods can be applied to all kinds of water provided that the amount and nature of suspended solids and/or dissolved matter do not interfere with the concentration procedure. ISO 10705-3:2003 does not give specific details of concentration methods, but outlines the fundamental principles for evaluating the suitability of a particular method for a given type and volume of water. Annex A gives examples of methods that have been found satisfactory and their fields of application.
