ISO 11731 Legionella Detection in Environmental Water Samples Laboratory Testing Service by Eurolab

ISO 11731 is an international standard for the detection of Legionella bacteria in environmental water samples. The standard provides guidelines and requirements for laboratory testing, including sample collection, preparation, and analysis methods.

The standard is developed and maintained by the International Organization for Standardization (ISO), which is a non-governmental organization that brings together experts from around the world to develop and maintain standards. ISO 11731 is part of the ISO 16140 series, which deals with microbiological methods for the detection of microorganisms in water.

The standard has undergone several revisions since its initial publication in 1998. The current version, ISO 11731:2017, provides updated guidelines and requirements for laboratory testing, including new methodologies and technologies.

International and National Standards

ISO 11731 is recognized as an international standard by many countries around the world. In Europe, the standard is implemented through EN ISO 11731, which is a harmonized European standard. In Turkey, the standard is adopted as TSE-EN ISO 11731.

The standard is also referenced in various national regulations and guidelines related to water safety and quality. For example, in the United States, the standard is recognized by the Environmental Protection Agency (EPA) as a recommended method for detecting Legionella bacteria in drinking water.

Standard Development Organizations

The development of ISO 11731 involves collaboration between several standard development organizations, including:

  • International Organization for Standardization (ISO)

  • European Committee for Standardization (CEN)

  • Turkish Standards Institution (TSE)

    • These organizations bring together experts from around the world to develop and maintain standards. The development process involves a rigorous review and approval process, which ensures that the standard meets the needs of users and stakeholders.

    Standard Evolution and Update

    Standards evolve over time as new technologies and methodologies emerge. ISO 11731 has undergone several revisions since its initial publication in 1998. The current version provides updated guidelines and requirements for laboratory testing, including new methodologies and technologies.

    The standard is reviewed and updated regularly to reflect changes in technology, scientific knowledge, and user needs. This ensures that the standard remains relevant and effective in supporting safe drinking water and public health.
