3-2 International Inter-laboratory Study (IIS) Initiated (Samples Sent to Labs) in March of 2017 Four Samples Included Varying Amounts of F, Cl, Br & I 20 Laboratories Invited 7 Laboratories Accepted 6 Laboratories Have Returned Results

IIS 3-2 Fluorine Sample B02 Results show good correlation to the expected value Sample D04 No F expected but reported by all labs (less than 0,02%)

IIS 3-2 Chlorine & Bromine Results show good correlation to the expected values

IIS 3-2 Iodine 2 results are good 1 result is acceptable 3 results are too low

IIS 3-2 Conclusions Results for F, Cl, and Br were good Results for F in sample IIS3-D04 need further investigation as no F was expected. Results for I were low / inconsistent More lab data is needed A second IIS incorporating new samples and methodology to account for low / inconsistent iodine.
