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.

NSF/ANSI 49-2018
Biosafety Cabinetry - Design, Construction, Performance, and Field Certification
This Standard applies to Class II (laminar flow) biosafety cabinetry designed to minimize hazards inherent in work with agents assigned to Biosafety Levels 1, 2, 3, or 4. It also defines the tests that shall be passed by such cabinetry to meet this Standard. This Standard includes basic requirements for the design, construction, and performance of biosafety cabinets (BSCs) that are intended to provide personnel, product, and environmental protection; reliable operation; durability and structural stability; cleanability; limitations on noise level; illumination; vibration; and motor / blower performance.
NSF/IPEC/ANSI 363-2016
Good Manufacturing Practices (GMP) for Pharmaceutical Excipients
The principles outlined in this Standard provide a comprehensive basis for the quality management system used in the manufacture of pharmaceutical excipients.
NSF/ANSI 173-2018
Dietary Supplements
This Standard provides test methods and evaluation criteria for dietary supplement products to allow for the determination that the ingredients in the product are accurately identified, that the product contains the quantity of dietary ingredients and marker constituents declared on the product label, and that the product does not contain unacceptable quantities of contaminants. This Standard provides criteria for determining that good manufacturing practices (GMP) were followed in the production of dietary supplements.
NSF/ANSI 51-2019
Food Equipment Materials
This Standard establishes minimum public health and sanitation requirements for materials used in the construction of commercial food equipment. The requirements of this Standard are intended to ensure that the composition and surface finish of food equipment materials are such that a material will not adulterate food nor render food equipment difficult to clean and sanitize.
NSF/ANSI 372-2016
Drinking Water System Components - Lead Content
This standard establishes procedures for the determination of lead content based on the wetted surface areas of products.
NSF/ANSI/3A 14159-1-2019
Hygiene Requirements for the Design of Meat and Poultry Processing Equipment
Applies to equipment intended for use in the slaughter, processing, and packaging of meat and poultry products, excluding hand held tools and mechanical belt conveyors. The requirements are to be applied by designers and manufacturers who in turn are to provide guidance to the users for the intended use of the equipment.
NSF/ANSI 61-2016
Drinking water system components - Health effects - with Addendum
This Standard establishes minimum health effects requirements for the chemical contaminants and impurities that are indirectly imparted to drinking water from products, components, and materials used in drinking water systems.
NSF/ANSI 7-2016
Commercial Refrigerators and Freezers
This Standard contains requirements for refrigerators and freezers used to store and/or display cold food. The types of refrigerators and freezers covered by this Standard include, but are not limited to: storage refrigerators (e.g., reach-in, under counter, walk-in, roll-in); storage freezers (e.g., reach-in, under counter, walk-in, roll-in); rapid pull-down refrigerators and freezers; refrigerated food transport cabinets; refrigerated buffet units; refrigerated food preparation units; display refrigerators; beverage coolers; and ice cream cabinets. This Standard does not establish equipment installation requirements. While the requirements of this Standard are intended to ensure that equipment may be installed in a sanitary manner, proper installation of equipment shall be governed by the applicable codes. Refrigerator and freezer components and materials covered under other NSF or NSF/ANSI Standards or Criteria shall also conform to the requirements therein. This Standard is not intended to restrict new unit design, provided that such design meets the minimum specifications described herein. 1.3 Alternate materials, design, and construction While specific materials, design, and construction may be stipulated in this Standard, equipment that incorporates alternate materials, design, or construction may be acceptable when such equipment meets the applicable requirements herein.

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. This Standard does not establish performance or taste and odor requirements for drinking water treatment chemicals.
