NSF Intl. Marks 50 Years of Recreational Water Testing, Certification

Program addresses safety needs and concerns of consumers, public health officials and product manufacturers

NSF Intl. announced that its Recreational Water Certification Program is celebrating 50 years of service, offering testing and certification solutions that aim to help the public swim more safely.

NSF Intl.’s Recreational Water Certification Program tests, inspects and certifies products for recreational water use, such as water circulation, filtration and treatment of residential and public swimming pools, spas, hot tubs and water parks. The certification program helps address the safety needs and concerns of consumers, public health officials and product manufacturers.

In 1960, four public health associations asked NSF Intl. to develop uniform, nationally acceptable public health and performance standards for swimming pool equipment, supplies and chemicals. These associations include American Public Health Assn., the Conference of Municipal Public Health Engineers, Conference of State Sanitary Engineers and The Association of Pool and Spa Professionals (APSP).

This request led to the formation of the NSF Joint Committee on Recreational Water Facilities. The group of federal and state public health authorities, manufacturers and equipment users developed a comprehensive and consensus-based American National Standard: NSF/ANSI Standard 50-Equipment for Swimming Pools, Spas, Hot Tubs and Other Recreational Water Facilities. The American National Standard contains requirements for an array of products including:

• Alerts and barriers such as pool alarms and pool/spa covers;
• Water circulation products such as pumps, pipes, suction fittings, safety vacuum release systems (SVRS), skimmers and valves;
• Water filtration materials and products such as pre-coat filters, media, bed filters, cartridge type filters and filtration media;
• Water treatment products such as UV and ozone systems, chemical generators, chemical feeders, brominators and chlorinators; and
• Advanced analytical and monitoring systems such as automatic controllers and water quality testing devices.

“NSF/ANSI Standard 50 continues to evolve to address new technologies with comprehensive evaluation criteria to verify product durability, functionality, performance, efficacy, health and safety,” said Bob Ferguson, vice president, NSF Intl.'s water programs. “Swimming pools, spas and recreational water facilities are great places for fun, exercise and family recreation; and NSF is committed to continually improving pool and spa safety through standards development, testing, certification and inspection."
