BS EN ISO 7899-2:2000

This standard BS EN ISO 7899-2:2000 Water quality. Detection and enumeration of intestinal enterococci in surface and waste water is classified in these ICS categories:

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

This part of ISO 7899 specifies a method for the detection and enumeration of intestinal enterococci in water by membrane filtration. This part of ISO 7899 is especially intended for examination of drinking water, water from swimming pools and other disinfected or clean waters. Nevertheless, the method can be applied to all types of water, except when a large amount of suspended matter or many interfering microorganisms are present. It is particularly suitable for the examination of large volumes of water containing only a few intestinal enterococci.
