This part of ISO 5815 specifies the determination of the biochemical oxygen demand of waters by dilution and seeding with suppression of nitrification after 5 d incubation time.
This part of ISO 5815 is applicable to all waters having biochemical oxygen demands usually between 3 mg/l and 6 000 mg/l. It applies particularly to waste waters. For biochemical oxygen demands greater than 6 000 mg/l of oxygen, the method is still applicable, but the errors caused by the necessary dilutions can influen...

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...

This International Standard defines a method for the determination of lipophilic substances of low volatility in water using gravimetry.
The method is applicable to all kinds of water and allows the determination of low-volatility lipophilic substances which are suspended, emulsified, or dissolved, in concentrations of about 10 mg/l to 500 mg/l.
Above this value, the test portion is diluted appropriately.
The method is not applicable to water with a separate oil layer.
