What standard covers materials that come into contact with drinking water?

NSF/ANSI Standard 61 specifically addresses the health effects of drinking water system components, ensuring that materials that come into contact with drinking water do not leach harmful substances into the water. This standard is crucial for safeguarding public health by establishing the requirements for the production and testing of various materials—such as pipes, fittings, and fixtures—to ensure they are safe for use in drinking water applications.

ISO 9001 pertains to quality management systems and does not specifically relate to materials contacting drinking water. ANSI Z84.39 mainly deals with safety standards for certain types of protective clearances and hearing protection, while ASTM D1193 focuses on water quality standards rather than materials that come in contact with drinking water. Hence, NSF/ANSI Standard 61 is the key standard for ensuring that materials used in the drinking water system are safe for public health.
