PFAS FREE VERIFICATION FOR FOOD SERVICE, PLUMBING AND WATER TREATMENT
IAPMO 409 Conformity Assessment Document – Products or Materials
The IAPMO 409 Conformity Assessment Document establishes a framework for verifying that food service, plumbing, water treatment products, and associated materials are free of intentionally added PFAS substances. The program provides manufacturers with a structured method for evaluating product composition, documenting material ingredients, and demonstrating compliance through independent review and ongoing verification activities.
PFAS, commonly referred to as “forever chemicals,” are a large class of fluorinated compounds that can persist in the environment and accumulate in water, soil, wildlife and humans. Growing regulatory requirements and increased public awareness have driven demand for product verification programs that address PFAS content through an entire product or materials.
