Results and discussion

Density
Type:
relative density
Density:
1.07 other: (corresponds to D4(20))
Temp.:
20 °C
Remarks on result:
other: test performed with an aqueous solution of test item

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).
