NSF/ANSI 50: Pools, Spas and Hot Tubs
NSF/ANSI 50: Equipment for Pools, Spas, Hot Tubs and Other Recreational Water Facilities was developed by a committee of experts comprised of manufacturers, public health officials and users. No other standard in the world has such complete evaluation and testing criteria.
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 many types of equipment used at a water-park, pool or spa equipment and components. The standard covers every form of pool and spa, public and private, and every component, from pumps and chemicals to suction fittings and water test devices. Equally important, NSF/ANSI Standard 50 is in a constant state of evolution, incorporating the latest product and material test methods and regulations.
