NSF/ANSI 50 Equipment for Swimming Pools, Spas, Hot Tubs and Other Recreational Water Facilities

摘要

NSF/ANSI 50 Equipment for Swimming Pools, Spas, Hot Tubs and Other Recreational Water Facilities includes requirements for a wide range of products and technologies. Equipment as diverse as pumps, sand filters and ultraviolet disinfection systems are all covered under various sections. In addition to a broad scope in terms of equipment covered, the end-use applications under this standard are also quite broad-everything from residential hot tubs all the way to commercial water parks is included under the standard. NSF/ANSI 50 includes general requirements for materials in contact with recreational water, including safety against leaching of harmful chemicals and corrosion resistance. Additional general requirements exist for design and construction of various types of equipment. For example, seals are required to be free of leaks and piping assemblies are required to be able to be disassembled for repair.
