Since its founding more than 70 years ago, NSF International has become one of the most trusted names in public health, writing national standards and testing and certifying products.
Widely recognized for its scientific and technical expertise, NSF has developed more than 90 public health and safety standards, including standards for drinking water, pools and spas, and many more.
As a third-party expert, NSF International was asked in the 1960’s to develop technical evaluation standards for testing and certifying pool- and spa-related materials, chemicals and products. Today, NSF/ANSI 50: Equipment for Swimming Pools, Spas, Hot Tubs and Other Recreational Water Facilities is the primary certification standard in North America for pool and spa products and components, from pumps and chemicals to suction fittings and water test devices. NSF 50 is a unique standard, there is no similar criteria encompassing so many product elsewhere in the world. That’s why product manufacturers throughout the world use the NSFs Standard 50 Certification to help them meet the needs of owners, facility operators, inspectors, and public health officials.
NSF/ANSI 50 specifies requirements for the material health effects, corrosion resistance, performance, disinfection efficacy, durability testing, design and construction, marking and user instructions for equipment used at a waterpark, pool or spa, public and private.
To facilitate industry adoption of new technologies, NSF/ANSI 50 is regularly updated to incorporate the latest product and material test methods and regulation into its evaluation criteria for pool and spa type products that do not currently have detailed testing criteria within NSF/ANSI 50. Through this process, NSF is able to offer third-party testing and certification services to meet the needs of manufacturers, users and public health officials.
The NSF International mark is respected by public health officials, retailers and consumers worldwide as a symbol of product quality and integrity.
