Pool Pumps, Strainers and Variable Frequency Drives

With over 50 years of experience certifying pool pumps, strainers and variable frequency drives, NSF International is known as the recreational water industry’s leading testing and certification organization. Certification to NSF/ANSI 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.

Pool Drains, Suction Fittings and Grates

As a renowned leader in water safety, NSF has the in-house capacity, knowledge and expertise to serve your certification needs. The Virginia Graeme Baker Pool and Spa Safety Act requires certification to ANSI/APSP-16 Standard Suction Fittings for Use in Swimming Pools, Wading Pools, Spas and Hot Tubs.

To achieve the highest level of product acceptance in the industry, NSF certification of your pool drains, suction fittings and grates to ANSI/APSP 16 and NSF/ANSI 50: Equipment for Pools, Spas, Hot Tubs and Other Recreational Water Facilities helps ensure product compliance. The NSF mark, respected by public health officials, retailers and consumers, is recognized as a symbol of product quality and integrity.

Pool Chemicals

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.

Additional Pool Products

If you manufacture equipment, components or chemicals used in pools, spas, splash pads or other aquatic venues in North America, your products are required to comply with NSF/ANSI 50: Equipment for Swimming Pools, Spas, Hot Tubs and Other Recreational Water Facilities by most state agencies. Developed by a team of scientists, industry experts and key industry stakeholders, NSF/ANSI 50 sets health effects criteria, operational safety and performance verification for many recreational water products including:

  • Automatic controllers
  • Chemicals
  • Chemical generators and feeders
  • Filters (DE, sand, cartridge)
  • Flow meters
  • Pool alarms
  • Pumps and strainers
  • Ozone generators
  • Suction fittings and main drains
  • UV systems
  • Valves
  • Water quality test devices
  • And more
