NF EN ISO 11348-1
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
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.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
