Scope

ISO 11348 describes three methods for determining the inhibition of the luminescence emitted by the marine bacterium Vibrio fischeri (NRRL B‑11177). ISO 11348-3:2007 specifies a method using freeze‑dried bacteria.
This method is applicable to:

waste water;
aqueous extracts and leachates;
fresh water (surface and ground water);
sea and brackish water;
eluates of sediment (freshwater, brackish and sea water);
pore water;
single substances, diluted in water.
