* = Only include Criteria 1
(X) = Wants a summation limit of 0,9 % for Cl and Br only.
X1 = Raw material suppliers want to keep, article suppliers want to remove
X2 = Raw material suppliers want to remove, EEE product manufacturers want to keep
X3 = Some want a two level definition, DB Criteria 1,2&3 as “LH Basic” and Summation limit with DB Criteria 1,2+3 as “LH Advanced”. Others don´t want a two level definition.

7. 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

8. 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%)

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

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

11. 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.
