标准简介
This Standard sets out a method, using membrane filtration, for enumerating coliforms in water.NOTES:1 Membrane filtration is suitable for enumerating microorganisms only when the turbidity of the water is low.2 The membrane filtration method is not suitable for waters containing only small numbers of coliforms in the presence of many other species that are capable of growth on the medium used.3 Bacterial counts derived from membranes with fewer than 20 or more than 80 coliform colonies are approximate.4 A flow diagram of the procedure is shown in Appendix A.
