# PFAS in AFFF reference materials

## Appears In

                        - NIST Researchers Develop Standards to Help Eliminate ‘Forever Chemicals’ in Firefighting Foams
                        - National Institute of Standards and Technology

A series of reference materials contain precise measurements of per- and polyfluoroalkyl substances (PFAS), known as forever chemicals, in firefighting foams. These foams, called aqueous film-forming foams (AFFFs), are used to suppress fuel fires. Analytical labs can use the reference materials for measuring PFAS in the foams so they can be removed.
