Comprehensive Guide to ISO 17994 Method Comparison for Drinking Water Microbiology Testing Services

Standard-Related Information

ISO 17994 is an international standard that governs the method comparison for drinking water microbiology testing. This standard is published by the International Organization for Standardization (ISO) and is applicable to laboratories performing microbiological analysis of drinking water.

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

  • EU Drinking Water Directive (98/83/EC)

  • US Environmental Protection Agency (EPA) regulations

  • World Health Organization (WHO) guidelines for drinking water quality

    • The standard requires laboratories to compare the results of their microbiological analysis with those obtained using a reference method. This is to ensure that the laboratorys results are reliable and comparable to other laboratories.
