BS ISO 10705-3:2003

This standard BS ISO 10705-3:2003 Water quality. Detection and enumeration of bacteriophages is classified in these ICS categories:

• 13.060.70 Examination of biological properties of water
• 07.100.20 Microbiology of water

This part of ISO 10705 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.

This part of ISO 10705 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.
