EN 12341 Organic Contaminant Sampling in Water: Eurolabs Laboratory Testing Service

EN 12341 is a European standard for the sampling of water intended for human consumption, including drinking water and raw water. The standard outlines the requirements for sampling, sample handling, and testing to ensure that the water meets the necessary quality standards.

Background and History

The development of EN 12341 began in the early 1990s as part of a broader effort to harmonize European standards for water quality. The standard was first published in 1996 and has since undergone several revisions to reflect changing regulatory requirements and advances in analytical techniques.

International and National Standards

EN 12341 is based on international standards, including ISO 5667 (Water Quality - Sampling) and ASTM D7348-13 (Standard Guide for Selection of Water Samples for Trace Organic Chemical Analysis). The standard also references national standards, such as the German DIN EN 12341:2003.

Standard Development Organizations

The development and maintenance of EN 12341 is overseen by CEN (European Committee for Standardization), which is responsible for developing and publishing European standards. CEN works closely with other standard development organizations, including ISO and ASTM, to ensure harmonization and consistency across different regions and industries.

Evolution of Standards

Standards evolve over time in response to changing regulatory requirements, advances in analytical techniques, and emerging contaminants of concern. EN 12341 has undergone several revisions since its initial publication, with the most recent revision (EN 12341:2018) reflecting changes to the European Drinking Water Directive.

Specific Standard Numbers and Scope

The scope of EN 12341 includes:

  • Sampling of water intended for human consumption

  • Sampling of raw water sources, including rivers, lakes, and groundwater aquifers

  • Sample handling and storage requirements

  • Testing for a range of organic contaminants, including pesticides, industrial chemicals, and pharmaceuticals

    • Standard Compliance Requirements

    EN 12341 is applicable to all organizations involved in the sampling and testing of water intended for human consumption. Compliance with the standard is mandatory for laboratories conducting water quality testing.
