NSF 61 Compounds


NSF International is a not-for-profit organization whose mission is to facilitate public health and safety standards, and to provide testing services to those standards. Although conformance to these standards is voluntary, in many industries NSF International standards have become the de facto benchmark for consumer product acceptability.

In the rubber industry, the most important standard by far is "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, whether the level of migration is acceptable from a public health viewpoint.

RT Dygert is pleased to present a multitude of NSF Standard 61 certified compounds per the following table. In all cases, these compounds also comply with FDA requirements per 21CFR, 177-2600, a-d. For more information about NSF, please visit or call our sales department.
