标准简介
This Standard sets out a method, using membrane filtration, for enumerating thermotolerant coliforms and Escherichia coli in water.NOTES:1 Thermotolerant coliforms are often also referred to as 'faecal coliforms' although the organisms may not be of faecal origin.2 Membrane filtration is suitable for enumerating microorganisms only when the turbidity of the water is low.3 Bacterial counts derived from membranes with fewer than 20 or more than 80 thermotolerant coliform colonies are approximate.4 A flow diagram of the procedure is shown in Appendix A.
