Chlorinated Water Testing Under the EU Drinking Water Directive

January 12, 2026

Under the revised EU Drinking Water Directive (EU 2020/2184), chlorinated water testing is now mandatory for evaluating materials and products that come into contact with drinking water.

What is chlorinated water testing under EU-MHR?

In the context of the minimum hygiene requirements (EU-MHR) under the EU DWD, working with a certification body experienced in chlorinated water testing provides manufacturers with a strategic advantage—ensuring accurate, qualified test results and supporting compliance with EU regulations.

NSF expertise in chlorinated water testing for plastic pipes

NSF has been a leader in testing and certifying products that come into contact with chlorinated water—particularly plastic pipes. Because chlorine is widely used in the U.S. as a disinfectant for drinking water, we understand from experience how it can influence extraction testing and impact test results.

Since the development of NSF/ANSI 14 in 1965 and NSF/ANSI/CAN 61 in 1988, NSF has built extensive expertise in this area. Manufacturers can leverage this knowledge to ensure accurate testing, reliable certification, and compliance with both U.S. and EU requirements.
