REACH PFOA Restriction Enforcement
Development of EU standardised analytical methods
Background and Purpose
o REACH PFOA Restriction sets forth two different concentration limits: 25 ppb for PFOA and its salts and 1 000 ppb for one or a combination of PFOA-related substances, in other substances, mixtures or articles
o Recital 12 states that "The deferral period for the restriction should allow the further development of suitable analytical methods that can be applied to all matrices. "
o The FluoroCouncil would like to highlight the complexity of developing reproducible, cost-efficient analytical methods for all matrices in scope and against the given thresholds
o The FluoroCouncil would like to underline the importance of timely adoption of analytical methods to enable effective enforcement
o The FluoroCouncil is willing to take part in the process to share its knowledge and experience

FluoroTechnology
Fluorotelomer-based products - Fluoropolymers
Fluorotelomer-based products: polymers and
surfactants
"Short" fluorinated chains that may be attached to organic polymer backbones
Modify material properties: surface modification & protection, water & oil repellency; soil resistance, wetting and spreading
Applications: Textiles, Carpets, Paper, Stone & Tile, AFFF, Surfactants
Fluoropolymers (Fluoroplastics & fluoroelastomers)
High molecular weight polymers
PTFE, Melt Copolymers, Thermoset Elastomers
Fluorinated "backbone"
Material properties: chemical resistance, thermal stability, resilience (elastomers)
Applications: Breathable membranes, Aerospace Materials, Hydraulic tubing, Chemical Processing , Semiconductor Manufacture, Transportation

FluoroCouncil's views on analytical methods to enforce the REACH PFOA Restriction
6
What is needed?
o European Standard in order to demonstrate if the limit values set in the REACH PFOA Restriction are met or not, for :
1. Fluorotelomers (fluorinated polymers and surfactants) 2. Fluoropolymers and fluoroelastomers (not covered as such by the Restriction)
o Initial screening methods, easier to implement and less costly for enforcers
Target analytes Sampling preparation
FLUOROTELOMERS: FLUORINATED POLYMERS AND
SURFACTANTS
FLUOROPOLYMERS AND FLUOROELASTOMERS
PFOA, 8:2 FTOH, monomer (fluorinated polymers), 8:2 FTS
(AFFF)
PFOA
Matrix dependent: textile, firefighting foams etc.
May differ between different forms of fluoropolymers and fluoroelastomers and matrix
7
FluoroCouncil's recommendations
Analytical standards methods should take most account of the following two aspects:
Practicability
While sample preparation is matrix dependent, the analytical methods should be broadly available and applicable to the largest possible scope of products
Economic feasibility
The analyticals methods should not result in too high costs for industry and enforcers

Standard development process
o PFOS precedent with CEN/TS 15968:
o To our knowledge, technical specifications not yet converted to a European standard mainly related to reproducibility issues
o Highlights complexity of the issue and extension to PFOA and PFOArelated substances.
o Next steps in development of analytical methods and possibilities for the FluoroCouncil to take part in the process?
o How could the Commission / ECHA Enforcement Forum support enforcement of the Restriction by competent national authorities?
