Overview
ISO 11348-2:2007/Amd 1:2018 is an important international standard issued by the International Organization for Standardization (ISO) under the technical committee ISO/TC 147 (Water quality) and its biological methods subcommittee SC 5. This amendment revises the Part 2 method of the series ISO 11348, focused on the determination of the inhibitory effect of water samples on the bioluminescence of Vibrio fischeri, a luminescent marine bacterium. The method utilizes liquid-dried Vibrio fischeri bacteria to assess water toxicity via its impact on bacterial light emission.
This test is widely recognized for its sensitivity and rapid detection of toxic substances in water, contributing to water quality monitoring and environmental safety compliance.
Key Topics
- Luminescent Bacteria Test (LBT): Uses the naturally bioluminescent marine bacterium Vibrio fischeri to detect inhibitors in water samples by measuring changes in light emission.
- Liquid-Dried Bacteria Method: Utilizes freeze-dried or liquid-dried Vibrio fischeri cultures, allowing easier storage and preparation for testing without compromising test sensitivity.
- Inhibitory Effect Measurement: Quantifies the reduction in bioluminescence intensity caused by toxic pollutants present in water, providing an indicator of sample toxicity.
- Method Performance Criteria: Amendment 1 specifies enhanced reproducibility and accuracy requirements such as limiting dilution variance within 3 percentage points of the mean DMSE (Dilution Mean Sublethal Effect).
- Standardization and Compliance: Follows ISO/IEC directives, ensuring global acceptance and harmonization in water toxicity testing methods.
- Intellectual Property Note: The standard may include proprietary details or patented methods essential for full implementation.
Applications
- Water Quality Monitoring: Rapid toxicity screening of surface water, wastewater, and industrial effluents to ensure safety and regulatory compliance.
- Environmental Impact Assessments: Detect effects of pollutants on aquatic ecosystems before approving discharge or remediation actions.
- Industrial Process Control: Monitor presence of harmful substances in manufacturing discharge streams to prevent environmental contamination.
- Research and Development: Evaluate new chemical substances or environmental treatment methods by toxicity bioassays.
- Regulatory Testing: Provide scientifically validated data for environmental agencies to support water quality standards and pollution control programs.
Related Standards
- ISO 11348-1: Testing method using freeze-dried bacteria for comparative toxicity assessments.
- ISO 11348-3: Protocol for testing water samples using bacterial cultures in liquid form.
- ISO 5667 Series: Standards for water sampling techniques complementing toxicity testing processes.
- ISO/IEC Directives, Part 1 and 2: Guidelines for the development and drafting of ISO standards ensuring clarity and universal applicability.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
