Applicant's summary and conclusion

Conclusions:

The relative density of the aqueous solution was determined to be 1.0708 at 20°C. The relative density of the solidified material could not be measured due to its high viscosity.

Executive summary:

The test was performed in 2000 under GLP according to the Czechian testing method 1.4.2 (similar to method A.3 of Directive 67/548/EEC).
