ISO 9308-1:2000/cor 1:2007 PDF

Scope: This part of ISO 9308 describes a reference method (Standard Test) for the detection and enumeration of Escherichia coli and coliform bacteria in water for human consumption. The Standard Test has a low selectivity, allowing the detection of injured bacteria. Due to the low selectivity, background growth can interfere with the reliable enumeration of coliform bacteria and E. coli, for example in some drinking waters, like shallow well waters or surface waters. This method is not suitable for these types of water. The Standard Test is based on membrane filtration, subsequent culture on a differential agar medium and calculation of the number of target organisms in the sample.
