What is involved in the NSF/ANSI Standard 61 Certification process?
• Application – NSF/ANSI Standard 61 requires a disclosure by the manufacturer of all water contact materials in the product and a disclosure by the manufacturer’s material suppliers of all chemical ingredients in the materials. • Formulation, toxicology and product use information – Client and suppliers complete and submit NSF’s Product Information Form. This provides formulation, toxicology and product use information. • NSF formulation review – NSF toxicologists perform a formulation review for each water contact material to determine any possible ingredients, contaminants, or reaction by-products that may potentially leach from the material into drinking water. This formulation review then determines the battery of chemical analyses that will be performed on a particular material. • Plant audit and sample collection – NSF then conducts an inspection of the production facility to verify the product formulation and production process and to ensure adequate quality control procedures
The NSF Certification process has five basic steps: NSF/ANSI Standard 61 requires a disclosure by the manufacturer of all water contact materials in the product, and a disclosure by the manufacturer’s material suppliers of all chemical ingredients in the materials. NSF toxicologists perform a formulation review for each water contact material to determine any possible ingredients, contaminants or reaction by-products that may potentially leach from the material into drinking water. This formulation review then determines the battery of chemical analyses that will be performed on a particular material. NSF then conducts an inspection of the production facility to verify the product formulation and production process and to ensure adequate quality control procedures are in place to prevent the use of unauthorized materials. Product samples are collected during the inspection and sent to NSF laboratories to be tested to the appropriate exposure protocol of NSF/ANSI Standard 61. Devices or
