NSF Standard 61 compounds

The National Sanitation Foundation (NSF) is a not-for-profit organizations whose mission is to facilitate of public health and safety standards, and to provide testing services to those standards. Although conformance to these standards is voluntary, in many industries NSF standards have become the de facto benchmark for consumer product acceptability. In the rubber industry, the most important standard by far, is the “NSF Standard 61: Drinking Water System Components – Health Effects”. 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. These compounds also comply with FDA requirements per CFR21, 177-2600, a-d.
