ISO 11133-4 Detection of Waterborne Pathogens

ISO 11133-4 Detection of Waterborne Pathogens Laboratory Testing Service: A Comprehensive Guide

The ISO 11133-4 standard is a widely recognized international standard that governs the detection of waterborne pathogens in drinking water. This standard is developed and maintained by the International Organization for Standardization (ISO), with input from various technical committees, including those from the American Society for Testing and Materials (ASTM) and the European Committee for Standardization (CEN).

Legal and Regulatory Framework

The legal and regulatory framework surrounding ISO 11133-4 testing is complex and varied across different countries. In the United States, for example, the Environmental Protection Agency (EPA) sets standards for drinking water quality under the Safe Drinking Water Act (SDWA). Similarly, in Europe, the European Unions Drinking Water Directive (98/83/EC) establishes mandatory limits for various contaminants, including waterborne pathogens.

International and National Standards

The following international and national standards apply to ISO 11133-4 testing:
