Comprehensive Guide to ISO 17994 Comparison Method for Microbial Testing Results in Water Laboratory Testing Service Provided by Eurolab

ISO 17994 is a widely recognized international standard that outlines the comparison method for microbial testing results in water. This standard is published by the International Organization for Standardization (ISO) and is designed to provide a framework for laboratories to follow when conducting microbial testing on water samples.

The legal and regulatory framework surrounding this testing service is governed by various national and international standards, including:

  • ISO 17994:2017(E)

  • ASTM D1065-15

  • EN 12904:2001A1:2008

  • TSE 543:2017

    • These standards outline the requirements for microbial testing on water samples, including the methods and procedures for sampling, testing, and reporting.

    The international standard development organizations that contribute to this standard include:

  • ISO (International Organization for Standardization)

  • ASTM (American Society for Testing and Materials)

  • CEN (European Committee for Standardization)

    • These organizations work together to develop and maintain standards that are globally recognized and adopted.

    Standards evolve over time as new technologies and methodologies emerge. The development process involves a rigorous review and approval process to ensure that the updated standard is accurate, reliable, and relevant to industry needs.
