NSF International

NSF International, founded as the National Sanitation Foundation, works to standardize sanitation and food related requirements. Later expanding into other industries and changing their name to NSF International, NSF has a strong focus on food and water safety, as well as certification and testing for those fields. Serving companies in other 150 countries, NSF-developed standards play a key role in health codes in America and abroad. Standards from NSF are available both individually, directly through the ANSI webstore, and as part of a Standards Subscription. If you or your organization are interested in easy, managed, online access to standards that can be shared, a Standards Subscription may be what you need - please contact us at: StandardsSubscriptions@ansi.org or 1-212-642-4980 or Request Proposal Price.

Below are NSF's best-selling standards. To find additional standards, please use the search bar above.

NSF P231-2003

Microbiological Water Purifiers

Microbiological water purifiers use chemical, mechanical, and/or physical technologies to filter and treat waters of unknown microbiological quality, but are presumed to be potable. This protocol addresses systems having a flow rate of 5 gpm or less and contains minimum requirements for materials, design and construction, and performance of these systems. The systems are not intended to convert wastewater or raw sewage into drinking water. System components covered under other NSF or NSF/ANSI standards or criteria shall also comply with the requirements contained in those other standards. This protocol shall in no way restrict new system designs, provided such designs meet the minimum specifications described herein.


NSF/ANSI 60-2017

Drinking water treatment chemicals -Health effects

This Standard establishes minimum health effects requirements for the chemicals, the chemical contaminants, and the impurities that are directly added to drinking water from drinking water treatment chemicals.
