NSF International® - Potable Water Applications (ANSI/NSF Standard 61)

NSF International is an independent third party certifier that acts as a neutral agency among the interests of business, government and the public. Products certified and carrying the NSF mark signify that they have been proven safe for contacting products intended for human consumption. NSF is particularly known for its food related and potable water standards. Like the UL label, the NSF mark is given to the finished consumer product. Minnesota Rubber and Plastics will assist any customer in their quest to comply with any NSF standard. Minnesota Rubber and Plastics has the largest number of ANSI/NSF Standard 61 certified compounds available today. Approved material can be used in a wide variety of water applications and other NSF standards. By choosing a Standard 61 certified compound, customers realize large savings in product testing and time to certification for their product.
