Question:We would like to get some of our sealants approved for drinking water applications. How can we do this?
Answer: In the U.S., you need to get your products certified to the NSF/ANSI Standard 61 Drinking Water System Components—Health Effects standard, a voluntary consensus standard that is overseen by the American National Standards Institute (ANSI). ANSI does not test products, but six accredited organizations with test laboratories are available to certify products to this standard.
