NSF 61
NSF/ANSI 61 addresses the human health effects of drinking water system components. This performance-based standard evaluates the amount of contaminants that leach from the products into potable drinking water. The origin for this standard was lead reduction/ removal. Any lead that elutes into the water at over 0.25% fails this standard.
