  • Potable vs. Recreational Water Certification

As a world leader in testing and certification for recreational water products, NSF International was the first to publish an American National Standard to address the health effects of pool and spa treatment chemicals. This addition to longtime industry standard NSF/ANSI 50: Equipment for Pools, Spas, Hot Tubs and Other Recreational Water Facilities addresses the risk and toxicity of pool chemicals. The standard now provides criteria for testing for trace contaminants in chemicals, which are used in the treatment and circulation systems of swimming pools, spas and water parks.

The scope of this addition to NSF/ANSI 50 includes criteria for the evaluation of pool and spa treatment chemicals for the effects of dermal contact, inhalation and ingestion exposures.

Benefits of Certification

NSF/ANSI 50, a well-known industry standard, is your key to market access by showing your compliance with all model pool and spa codes, public health requirements and bid specifications.

NSF has been testing and certifying recreational water applications for over 50 years. With our technical proficiency, in-house testing capacity and industry recognition, NSF certification for pool treatment chemicals means faster market access and expedited regulatory acceptance.

Why Work With NSF?

NSF is the first organization to create an American National Standard for the health effects of pool chemicals, based on our expertise testing and certifying products for the recreational water industry. With experienced lab technicians and a staff of certified chemists, your products will be tested to the most recognized industry standard, by those who helped create it.

Certification Process

We have helped thousands of manufacturers obtain both local and international market access by evaluating products to meet the requirements of multiple markets and product standards. While we distinguish ourselves through product evaluation, we have made the process simple and efficient for you.

Seven Simple Steps to Certification

  1. Your company submits an application.
  2. You provide product formulation, toxicology and product use information.
  3. Our technical team reviews formulations.
  4. We perform a plant audit and sample collection.
  5. Our laboratory conducts testing.
  6. We complete a final toxicology evaluation.
  7. We grant NSF certification for compliant products and you can use the NSF mark on products, packaging and marketing materials.

Potable vs. Recreational Water Certification

Prior to the development of NSF/ANSI 50 Annex R (Toxicology Review and Evaluation Procedures for Swimming Pool Treatment Chemicals), there was no universally recognized protocol for the evaluation of pool chemicals. In many areas, product certification to NSF/ANSI/CAN 60: Drinking Water Treatment Chemicals - Health Effects is currently used as a requirement for regulatory acceptance of chemicals used in pool/spa water treatment. However, although NSF/ANSI/CAN 60 addresses oral exposure (of water treated with an NSF/ANSI/CAN 60 compliant chemical), it does not address dermal or inhalation exposure to treatment chemicals. Instead, these parameters are now included under NSF/ANSI 50 Annex R for pool chemicals.
