This part of ISO 9308 describes a procedure for counting Escherichia coli (E. coli) and coliform bacteria. The method is based on membrane filtration, subsequent cultivation on the chromogenic coliform agar (CCA) and calculation of the number of target organisms in the sample.

Our laboratory equipment for this method: Autoclaves 1, Autoclaves 2, Incubator

This part of ISO 7899 establishes a method for the detection and counting of intestinal enterococci in water by membrane filtration. This part of ISO 7899 is specifically intended for the examination of drinking water, water from swimming pools and other disinfected or clean waters. Nevertheless, the procedure can be applied to all types of water.

This International Standard establishes a procedure for the detection and counting of Pseudomonas aeruginosa in samples of bottled water using a membrane filtration method. This method is also suitable for other types of water with low flora, such as swimming and bathing pool water and water for human consumption.

This part of ISO 11731 describes a control procedure for the isolation and counting of Legionella in water intended for human consumption (e.g. hot and cold water, wash water), drinking water and treated pool water (e.g. swimming pool water). The process is particularly suitable for water with an expected low level of Legionella.
