Water treatment chemical certification

Our expertise encompasses all areas of water distribution, including water treatment chemical testing, certification, research and development.

If you manufacture, sell or distribute water treatment chemicals in North America, your products are required to comply with NSF/ANSI Standard 60: Drinking Water Treatment Chemicals – Health Effects by most governmental agencies that regulate drinking water supplies.

Developed by a team of scientists, industry experts and key industry stakeholders, NSF/ANSI 60 sets health effects criteria for many water treatment chemicals, including:

  • Corrosion and scale inhibitors
  • Coagulants and flocculants
  • Disinfection and oxidation chemicals
  • pH adjustment, softening, precipitation and sequestering chemicals
  • Well drilling aids
  • All other specialty chemicals used in drinking water treatment

Municipal water product certification

NSF/ANSI Standard 61: Drinking Water System Components – Health Effects Certification is required by most governmental agencies that regulate drinking water supplies in North America. NSF/ANSI 61 sets health effects criteria for many water system components including:

  • Protective barrier materials (cements, paints, coatings)
  • Joining and sealing materials (gaskets, adhesives, lubricants)
  • Mechanical devices (water meters, valves, filters)
  • Pipes and related products (pipe, hose, fittings)
  • Plumbing devices (faucets, drinking fountains)
  • Process media (filter media, ion exchange resins)
  • Non-metallic potable water materials

Concrete site mix evaluation: drinking water contaminants can come from many sources, including the equipment used for water storage and transportation. Concrete used in large storage tanks, reservoirs and pipelines is usually a combination of cement, admixtures, curing compound, sand and gravel. It can also contain fly ash and other additives to strengthen the concrete and increase its durability. However, any of these additives can have contaminants that can cause compliance problems for the utility and present potential health risks to the consumer.

Low lead compliance: on January 4, 2014, the new US Safe Drinking Water Act (SDWA) requirements will go into effect requiring all pipes, pipe fittings, plumbing fittings and fixtures used for potable water to meet new lead free requirements. The SDWA will require all drinking water products sold or installed for public water systems or plumbing in facilities to meet a weighted average lead content of no more than 0.25%. Solder and flux continue to be held to 0.20%. We offer two options to help ensure your products meet the requirements and also comply with the new accepted criteria for lead extraction: NSF/ANSI 61 Annex G and NSF/ANSI 372.

Public drinking water equipment performance: this NSF guideline establishes performance requirements in the treatment and production of drinking water, and includes requirements such as the US EPA’s Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR). Certification to the Drinking Water Equipment Performance Program demonstrates compliance with federal testing requirements but also adds a unique audit component to prove that products are manufactured using recommended methods and processes.

POU/POE testing and certification

NSF writes standards and provides testing and certification services for point-of-use (POU) and point-of-entry (POE) drinking water treatment systems and components. Testing can include material safety, structural integrity and contaminant reduction testing. NSF is proud to run the world’s largest POU/POE test facility with 30 state-of-the-art water filter test rigs. Our capabilities are unmatched and include full chemical, microbiological and physical testing, as well as complete in-house toxicology expertise.

Faucets, plumbing fixtures and fittings

Our comprehensive testing and certification services help ensure your products comply with required performance standards and plumbing codes, including NSF, ASME, ASSE, CSA, ASTM, IAPMO, CISPI, AWWA and PDI written standards and the Uniform Plumbing Code®.

Whether you manufacture valves, faucets, copper tubing, sinks, thermostatic mixing valves, backflow preventers, toilets, septic tanks, showers or practically any other type of plumbing product, NSF can provide the testing and certifications you need to gain product acceptance and code compliance.

Plastic piping systems

NSF/ANSI Standard 14: Plastics Piping System Components and Related Materials Certification is required by all major plumbing codes, including the Uniform Plumbing Code®, the National Standard Plumbing Code® and the International Plumbing and Residential Code®.

NSF International is the plastic industry’s leading testing and certification organization, with proven experience in certifying various types of plastic pipes and fittings used in today’s global applications. Including drinking water, radiant floor heating systems, gas piping, electrical conduit and fire safety components, our experts can help ensure your product is tested and certified against the appropriate standards for your distribution strategy. Our expertise includes pressure testing, chlorine resistance testing, hydrostatic design stress (HDS), DWV, sewer, chemical resistance and more.

Recreational water, pools and spas

NSF International is known as the recreational water industry’s leading testing and certification organization. Certification to NSF/ANSI Standard 50: Equipment for Pools, Spas, Hot Tubs and Other Recreational Water Facilities helps ensure that your pool pumps, strainers and variable frequency drives meet the technical evaluation, claims validation and testing criteria necessary to meet the standards set by your public health department.
