NSF/ANSI 61
NSF/ANSI 61 is a health and safety standard that ensures drinking water system components, such as pipes and fittings, do not leach harmful substances into the water. Developed by the NSF International and the American National Standards Institute (ANSI), it evaluates materials for their safety and impact on drinking water quality. Products that meet this standard are tested and certified for use in drinking water systems to protect public health, ensuring that materials used in plumbing, tanks, and treatment systems are safe, reliable, and supportive of clean and safe drinking water.
