NSF International is an international organization that tests and certifies products as safe.  Their standards are applied in many industries. In the rubber industry one of the more common standards is “NSF Standard 61: Drinking Water System Components – Health Effects”. Any supplier of drinking water knows their products must be be certified to NSF/ANSI Standard 61 (“NSF 61”).

The NSF Standard 61 sets limits for the amount of chemicals permitted to leach into drinking water from the materials used in water transmission and distribution.

Rubber compounds submitted to NSF undergo rigorous testing to determine whether any contaminants leach or migrate from the material when in long term contact with drinking water, and if so, if the level of migration is acceptable from a public health viewpoint.
