Applicant's summary and conclusion

Conclusions:
The water solubility of the test item has been determined to be greater than 25.1 % w/w of solution at 20.0 ± 0.5 °C.
Executive summary:

The water solubility of Lithium Bis(fluorosulfonyl)imide has been determined to be greater than 25.1 % w/w of solution at 20.0 ± 0.5 °C, by visual appraisal, based on the flask method, designed to be compatible with Method 105 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
