Topic: Total Fluorine Testing vs. Specific PFAS Testing
Many U.S. regulations, including California AB 1817 and industry standards like the AFIRM RSL, require compliance with total fluorine limits, rather than focusing only on specific PFAS compounds. Total fluorine testing (using methods like EN 14582:2016) quantifies all fluorine present. This is used as an indirect measure for PFAS presence but captures any fluorinated compounds, such as the fluorine from your tetrafluoroboric acid catalyst.
Total fluorine itself does not inherently indicate health risks since it encompasses both harmful PFAS compounds and benign fluorinated substances. However, regulators use total fluorine as a proxy to flag potential PFAS presence due to its cost-effectiveness. Direct PFAS testing (like EN ISO 23702-1 and EN 17681) focuses specifically on PFAS compounds, providing more targeted results - but at this time - not fulfilling total fluorine compliance requirements in the U.S.
Since your total fluorine levels exceed the 50 ppm threshold, your product could be non-compliant under current standards like CA AB 1817 and the upcoming AFIRM RSL requirements for 2027, even though no specific harmful PFAS were detected. Unfortunately, using EN ISO 23702-1 and EN 17681 to test for specific PFAS compounds does not substitute for total fluorine testing under these regulations.
We recommend contacting state regulatory officials to explain your unique situation, particularly the role of your fluorine-containing catalyst.
