This part of ISO 7027 specifies two quantitative methods using optical turbidimeters or nephelometers
for the determination of turbidity of water:
a) nephelometry, procedure for measurement of diffuse radiation, applicable to water of low turbidity
(for example drinking water);
b) turbidimetry, procedure for measurement of the attenuation of a radiant flux, more applicable to
highly turbid waters (for example waste waters or other cloudy waters).
Turbidities measured according to the first method are presented as nephelometric turbidity units
(NTU). The results typically range between <0,05 NTU and 400 NTU. Depending on the instrument
design, it can also be applicable to waters of higher turbidity. There is numerical equivalence of the
units NTU and formazin nephelometric unit (FNU).
Turbidity measured by the second method is expressed in formazin attenuation units (FAU), results
typically range between 40 FAU and 4 000 FAU.

This part of ISO 9308 specifies a method for the enumeration of Escherichia coli (E. coli) and coliform
bacteria. The method is based on membrane filtration, subsequent culture on a chromogenic coliform
agar medium, and calculation of the number of target organisms in the sample. Due to the low selectivity
of the differential agar medium, background growth can interfere with the reliable enumeration of
E. coli and coliform bacteria, for example, in surface waters or shallow well waters. This method is not
suitable for these types of water.
This part of ISO 9308 is especially suitable for waters with low bacterial numbers that will cause less
than 100 total colonies on chromogenic coliform agar (CCA). These may be drinking water, disinfected
pool water, or finished water from drinking water treatment plants.
Some strains of E. coli which are β-D-glucuronidase negative, such as Escherichia coli O157, will not be
detected as E. coli. As they are β-D-galactosidase positive, they will appear as coliform bacteria on this
chromogenic agar.

EN ISO 9308-2 specifies a method for the enumeration of E. coli and coliform bacteria in water. The method is based on the growth of target organisms in a liquid medium and calculation of the “Most Probable Number” (MPN) of organisms by reference to MPN tables. This method can be applied to all types of water, including those containing an appreciable amount of suspended matter and high background counts of heterotrophic bacteria. However, it must not be used for the enumeration of coliform bacteria in marine water. When using for the enumeration of E. coli in marine waters, a 1  10 dilution in sterile water is typically required, although the method has been shown to work well with some marine waters that have a lower than normal concentration of salts. In the absence of data to support the use of the method without dilution, a 1  10 dilution is used. This method relies upon the detection of E. coli based upon expression of the enzyme β-D-glucuronidase and consequently does not detect many of the enterohaemorhagic strains of E. coli, which do not typically express this enzyme. Additionally, there are a small number of other E. coli strains that do not express β-D-glucuronidase. The choice of tests used in the detection and confirmation of the coliform group of bacteria, including E. coli, can be regarded as part of a continuous sequence. The extent of confirmation with a particular sample depends partly on the nature of the water and partly on the reasons for the examination. The test described in this part of ISO 9308 provides a confirmed result with no requirement for further confirmation of positive wells.
