Water quality — Determination of the inhibitory effect of water samples on the light emission of Vibrio fischeri (Luminescent bacteria test) — Part 1: Method using freshly prepared bacteria

Scope

ISO 11348 describes three methods for determining the inhibition of the luminescence emitted by the marine bacterium Vibrio fischeri (NRRL B‑11177). ISO 11348-1:2007 specifies a method using freshly prepared 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 (fresh water, brackish and sea water);
pore water;
single substances, diluted in water.
